What to Put in Washing Machine to Clean It

Why Your Washing Machine Needs A Deep Clean

Your washing machine works hard, dealing with dirt, detergent residue, and moisture. Over time, this can lead to build-up within the drum, seals, and pipes, creating an environment where bacteria and mould can thrive. This not only affects the machine's performance, leaving clothes less than fresh, but can also cause unpleasant odours that transfer to your laundry. Understanding what to put in your washing machine to clean it is crucial for maintaining its efficiency and ensuring your clothes come out truly clean.

• Regular cleaning prevents mould and bacteria build-up.
• Addresses persistent odours and residue.
• Maintains washing machine efficiency.
• Extends the lifespan of your appliance.

The primary culprits behind a smelly or inefficient washing machine are detergent residue, fabric conditioner build-up, limescale, and dampness that encourages mould. These substances can accumulate in the drum, the rubber door seal (gasket), the detergent drawer, and crucially, the filter. If you've noticed a damp, musty smell clinging to your clothes even after a wash cycle, or if your machine is no longer draining or spinning effectively, it's a clear sign that a deep clean is overdue. Addressing these internal issues head-on requires specific cleaning agents designed to tackle these common problems within the appliance's intricate components.

Common Washing Machine Problems & Their Causes

The Persistent Musty Odour

This is perhaps the most common complaint. It often stems from a combination of residual detergent, fabric softener, and trapped moisture in the door seal and drum. Bacteria and mould feed on this organic matter, producing that tell-tale unpleasant smell. If left unchecked, these microbes can spread, impacting the freshness of your laundry.

Detergent and Fabric Softener Residue

Modern washing machines, especially front-loaders, are designed to use less water. While this is great for efficiency, it can also mean that detergent and fabric softener don't always rinse away completely. This residue builds up over time, creating a sticky film that can harbour bacteria and even affect the machine's draining system.

Limescale Accumulation

In hard water areas, limescale (calcium carbonate) can deposit on heating elements and internal parts. This reduces the machine's heating efficiency, leading to longer wash cycles and potentially impacting cleaning performance. It can also cause a gritty feel or even visible white deposits on laundry.

Clogged Washing Machine Filter

The washing machine filter, often located at the bottom front of the machine, traps lint, coins, buttons, and other debris. If this filter becomes clogged, it can prevent water from draining properly, leading to dampness, smells, and error codes. This is a critical component that often requires manual cleaning.

Effectively tackling these issues requires more than just running a hot wash with your regular laundry detergent. Specialised cleaning products and methods are needed to penetrate and break down the specific types of grime that accumulate inside the machine. The right approach will ensure your washing machine operates hygienically and efficiently for years to come.

The Best Agents for Cleaning Your Washing Machine

When it comes to cleaning your washing machine, the most effective approach often involves using products specifically formulated for this purpose. These agents are designed to break down the unique types of build-up that occur inside appliances, from detergent residue and fabric softener gunk to limescale and mould. You'll typically find these in two main forms: specialist washing machine cleaners, often available as tablets or liquids, and common household items that can achieve a similar result.

Choosing the right cleaning agent depends on the specific problem you're trying to solve. Are you dealing with a pervasive smell, heavy limescale, or general gunk build-up? Different products target different issues. For instance, while a hot wash can help, it won't effectively tackle ingrained mould or hardened detergent deposits without an appropriate cleaning agent. Ensuring you select an agent that aligns with the problem will yield the best results and prevent potential damage to your machine.

Specialist Washing Machine Cleaners

These products are engineered to dissolve detergent residue, limescale, and kill bacteria and mould. They are widely available from appliance manufacturers, supermarket brands, and specialist cleaning product companies. Using a dedicated cleaner is often the most straightforward and reliable method for a thorough internal clean.

Powders, Tablets, and Liquids

You'll commonly find washing machine cleaners in these formats:

• Tablets: Convenient and pre-measured, these are typically placed directly into the empty drum. They often contain a potent mix of descalers and cleaning agents.
• Liquids: These are usually poured directly into the detergent drawer or the main drum. They can be useful for targeting specific areas if the instructions allow.
• Powders: Similar to tablets, these are often added to the drum. Some powders are specifically designed for heavy limescale removal.

When selecting a brand, consider well-known names like Calgon, Dettol washing machine cleaner, or Dr. Beckmann washing machine cleaner, which have reputations for effective results. Always follow the product's instructions meticulously, as dosage and usage can vary.

Household Staples for a Clean Machine

If you don't have a specialist cleaner to hand, or prefer to use household items, a few common products can be surprisingly effective. These are cost-efficient and readily available.

White Vinegar

White vinegar is a fantastic natural descaler and disinfectant. Its acidity helps to break down limescale and kill bacteria. It's also excellent at deodorising. For a typical wash, you'll need about 250ml to 500ml of white vinegar. You can pour this directly into the detergent drawer or the main drum.

Bicarbonate of Soda (Baking Soda)

Bicarbonate of soda is a mild abrasive and a powerful deodoriser. It can help to scrub away residue and neutralise lingering odours. It's often used in conjunction with vinegar for a deeper clean, or on its own.

Bleach (Use with Extreme Caution)

While bleach can kill mould and bacteria effectively, it should be used with extreme caution and never mixed with vinegar or other acidic cleaners, as this can produce toxic fumes. If you choose to use bleach, dilute it according to the product's instructions (typically 1 part bleach to 4 parts water) and run a separate hot cycle. It's best reserved for stubborn mould issues, and often, specialist cleaners or vinegar are safer and equally effective alternatives.

The most critical factor is selecting an agent that will effectively break down the specific build-up causing your washing machine problems.

How to Clean Your Washing Machine: The Method

Once you've chosen your cleaning agent, the next step is the actual cleaning process. This usually involves running a high-temperature cycle with the chosen cleaner to allow it to circulate thoroughly and break down internal grime. It’s essential to follow a structured method to ensure all parts of the machine are addressed, from the drum and seals to the filter and detergent dispenser.

The method will vary slightly depending on whether you're using a specialist cleaner or household items like vinegar. However, the core principle remains the same: a hot wash cycle is key to dissolving and flushing away the accumulated residue. Always ensure the machine is empty of laundry before starting any cleaning cycle to allow the cleaner to work directly on the internal surfaces.

Step-by-Step Cleaning Guide

1. Empty the Machine: Ensure there is no laundry inside the drum.
2. Add the Cleaner:
   • Specialist Cleaner (Tablet/Powder): Place one tablet or the recommended amount of powder directly into the empty drum.
   • Specialist Cleaner (Liquid): Pour the recommended amount into the main drum or the detergent dispenser, following product instructions.
   • White Vinegar: Pour 250ml to 500ml of white vinegar into the main drum or the detergent dispenser.
   • Bicarbonate of Soda: Sprinkle about half a cup (around 100g) of bicarbonate of soda into the drum. If using with vinegar, add the vinegar to the dispenser and the bicarb to the drum.
3. Select the Right Cycle: Choose the hottest wash cycle available on your machine. A 90°C or 'Eco' cycle at a high temperature is ideal. If your machine has a specific 'drum clean' or 'machine clean' cycle, use that.
4. Run the Cycle: Let the washing machine run through the entire cycle. Avoid pausing it, as the extended period at high heat is crucial for the cleaner to work effectively.
5. Clean the Door Seal (Gasket): While the main cycle is running, or immediately afterwards, take a damp cloth (perhaps with a little vinegar or mild detergent solution) and thoroughly wipe down the rubber door seal. Pay close attention to the folds, where mould and grime often hide. For stubborn mould, a soft brush can help.
6. Clean the Detergent Drawer: Remove the detergent drawer (most can be pulled out completely). Soak it in warm, soapy water to loosen any residue, then scrub it clean with a brush and rinse thoroughly before replacing it.
7. Clean the Washing Machine Filter: This is a vital step often overlooked. Locate the filter at the bottom front of the machine (usually behind a small flap). Place a shallow tray or old towels underneath to catch any escaping water. Unscrew the filter slowly, allowing water to drain out. Once drained, pull the filter out, remove any lint, hair, coins, or debris, and rinse it under running water. Screw it back in securely.
8. Wipe Down the Exterior: Once the internal clean is complete, use a damp cloth to wipe down the exterior of the machine.

Post-Clean Check

After running the cleaning cycle and performing the manual cleaning steps, open the door and smell the drum. It should be fresh. Run a short, hot rinse cycle with just water to ensure all cleaning residue is flushed out.

Performing these steps regularly will keep your washing machine running efficiently and smelling fresh.

Tips for Maintaining a Clean Washing Machine

Preventing build-up is far more effective than cleaning it away later. Incorporating a few simple habits into your laundry routine can significantly extend the time between deep cleans and ensure your washing machine consistently performs at its best. These practices focus on reducing moisture, preventing residue accumulation, and ensuring proper airflow.

The key to long-term washing machine hygiene lies in managing moisture and airflow. Unlike older machines, many modern appliances, especially front-loaders, have seals designed to hold water, which is great for preventing leaks but creates an ideal environment for mould and mildew if left damp. Simple post-wash routines can make a world of difference.

Habits for Ongoing Hygiene

Make these practices part of your regular laundry schedule:

• Leave the Door Ajar: After each wash, leave the washing machine door open for a few hours, or ideally, overnight. This allows air to circulate inside the drum and the door seal, drying out any residual moisture and preventing mould growth.
• Wipe the Door Seal: Regularly wipe down the rubber door seal (gasket) with a dry cloth after each wash or at least once a week. This removes water droplets and any stray lint or hair before they can encourage mould.
• Empty the Detergent Drawer: If you notice residue building up in the detergent drawer, remove and clean it weekly or bi-weekly. Leaving it slightly ajar after use can also help it dry out.
• Use the Right Amount of Detergent: Overdosing on detergent, especially with high-efficiency (HE) machines, is a common cause of residue build-up. Always follow the manufacturer's recommendations and consider using less, particularly if you have soft water.
• Consider High-Temperature Washes: Once a month, run a hot wash cycle (60°C or higher) with a load of towels or bedding. This helps to kill bacteria and melt away grease and detergent build-up that cooler washes might leave behind.

Regular Filter Checks

As mentioned, the washing machine filter is a common site for debris. Check and clean it at least every 1-3 months, or more frequently if you have pets or notice longer draining times. A clogged filter not only affects drainage but can also contribute to odours.

When to Use a Specialist Cleaner

While good habits minimise build-up, it's still advisable to use a dedicated washing machine cleaner every 3-6 months, or sooner if you notice persistent smells or reduced performance. This ensures a thorough deep clean that routine maintenance might miss, tackling limescale and ingrained grime effectively.

Maintaining a clean washing machine is a proactive process, not a reactive one.

Always check your washing machine's manual for specific cleaning recommendations or warnings about using certain products, especially for high-efficiency or steam models.

By integrating these simple maintenance tips into your routine, you significantly reduce the likelihood of encountering common washing machine problems like foul odours or poor cleaning performance. This proactive approach saves time, money, and ensures your appliance serves you well for its intended lifespan.

Troubleshooting Specific Washing Machine Issues

Even with regular maintenance, you might encounter specific problems with your washing machine that a simple cleaning cycle might not fully resolve. Identifying the exact issue allows for a more targeted approach to cleaning and troubleshooting, ensuring your appliance is back to its best performance.

When your washing machine isn't performing as expected, it's often a sign that something internal isn't quite right. Whether it's a persistent smell that won't vanish, clothes not coming out as clean as they should, or unusual noises, these symptoms usually point to a specific underlying cause within the machine's components. Understanding these issues helps you know precisely what to put in the washing machine to clean it, or when to check specific parts.

Why Does My Washing Machine Smell?

A musty or sour smell is the most frequent complaint. This odour is typically caused by a combination of:

• Mould and Mildew: In the damp environment of the drum, door seal, and detergent drawer.
• Bacteria: Feeding on detergent residue, fabric softener, and bodily soils left on clothes.
• Clogged Filter: Trapped lint and debris can decompose, creating foul smells.

Remedy: A thorough clean as described above is essential. Focus particularly on cleaning the door seal and filter. Running a hot cycle with white vinegar or a specialist cleaner is usually effective. For persistent odours, you might need to repeat the process or consider a specific washing machine deodoriser.

Clothes Aren't Coming Out Clean

If your laundry isn't getting clean, or if you notice residue on your clothes, it could be due to:

• Detergent Build-up: Too much detergent or fabric softener can leave a film.
• Dirty Drum: Grime within the drum can transfer back onto clothes.
• Blocked Dispenser: If the detergent isn't dispensed correctly.
• Incorrect Cycle or Temperature: Using a low temperature for heavily soiled items won't be effective.

Remedy: Ensure you're using the correct amount of detergent for your water hardness and load size. Run a cleaning cycle with a descaler and detergent remover. Check that the dispenser is clean and that you're using appropriate wash cycles and temperatures for your laundry.

Water Not Draining Properly

This is usually a sign of a blockage. Common causes include:

• Clogged Filter: The most common culprit.
• Kinked or Blocked Drain Hose: The hose behind the machine might be bent or have an internal obstruction.
• Pump Impeller Blockage: Debris caught in the pump itself.

Remedy: First, check and clean the washing machine filter. If that doesn't solve it, inspect the drain hose for kinks or blockages. You may need to disconnect the hose to clear it. If the problem persists, the pump itself might need attention, which could require a service engineer.

Loud Noises During Operation

Unusual noises can indicate several issues:

• Loose Items: Coins, buttons, or other small objects in the drum or filter.
• Worn Drum Bearings: A grinding or rumbling noise, especially during spin cycles, often indicates worn bearings.
• Unbalanced Load: A load that's too heavy or unevenly distributed can cause banging during the spin cycle.

Remedy: Ensure the machine is on a level surface. Check the drum for loose items when empty and clean the filter. For bearing issues or persistent loud noises, professional servicing is usually required.

When investigating noises or blockages, always unplug the washing machine first for safety.

By addressing these common problems with the appropriate cleaning methods and maintenance, you can ensure your washing machine continues to deliver clean laundry efficiently and reliably.

Washing Machine Maintenance Schedules

Establishing a regular maintenance schedule is key to preventing problems and ensuring your washing machine operates at peak performance for as long as possible. It moves beyond reactive cleaning to proactive care, making sure the machine is consistently in good condition.

Think of it like servicing a car; consistent upkeep prevents major breakdowns and keeps everything running smoothly. The frequency of these tasks will depend on your usage, water hardness, and the type of detergents you use, but a general guideline can help you stay on track. This proactive approach not only saves you from inconvenient breakdowns but also helps maintain the quality of your washes.

Daily & Weekly Checks

These are the simplest tasks, designed to be integrated into your routine with minimal effort:

• After Each Wash: Leave the door ajar and wipe the rubber seal.
• Weekly: Wipe down the exterior and check the detergent drawer for obvious residue. Consider running a short, hot rinse cycle if you've washed heavily soiled items.

Monthly Maintenance

These tasks require slightly more time but are crucial for preventing build-up:

• Clean the Detergent Drawer: Remove and thoroughly clean it to remove any accumulated gunk.
• Clean the Washing Machine Filter: Inspect and clean the filter to remove lint, coins, and other debris.
• Run a Hot Cycle: Use a hot wash (60°C+) with an empty drum. You can add a cup of white vinegar or a specialist cleaner for a more thorough clean.

Quarterly & Bi-Annual Deep Cleans

These are more intensive cleaning sessions to tackle deeper issues:

Usage Tips for Longevity

• Use the Correct Detergent: High-efficiency (HE) detergents are formulated for low-water machines. Using the wrong type or amount can lead to excess suds and residue.
• Measure Accurately: Overdosing detergent is a primary cause of build-up. Follow the manufacturer’s guidelines.
• Avoid Fabric Softener Overuse: Fabric softeners leave residues that can build up in the drum and hoses. Consider alternatives or use sparingly.
• Don't Overload: Overloading strains the motor and bearings, and prevents clothes from washing and rinsing properly.
• Use Appropriate Cycles: For heavily soiled items, use hotter washes and appropriate detergents. For lightly soiled items, a cooler wash is sufficient and saves energy.

Adhering to a maintenance schedule ensures your washing machine remains a reliable appliance.

Understanding Washing Machine Cleaner Variations

The market offers a variety of products designed to clean your washing machine, each with slightly different formulations and intended uses. While some are general-purpose cleaners, others are specifically engineered to tackle particular issues like heavy limescale or stubborn mould. Understanding these variations can help you choose the most effective product for your machine's needs.

When you're looking at what to put in a washing machine to clean it, you'll see a range of options. Some are basic, while others incorporate advanced chemistries. Making an informed choice based on the specific problem you’re experiencing will lead to better results and a cleaner, more efficient appliance.

General Purpose Cleaners

These are your everyday, all-rounders. They typically contain a blend of surfactants, mild alkalis, and sometimes enzymes to break down common detergent residue, grease, and general grime. They are excellent for routine cleaning and preventing the build-up of everyday gunk. Most specialist washing machine cleaner tablets and liquids fall into this category, offering a convenient way to maintain the machine.

Limescale Removers

Formulated with strong acids, such as citric acid or specific descaling agents, these products are designed to dissolve mineral deposits left by hard water. If you live in a hard water area, limescale can build up on the heating element, affecting efficiency and potentially causing white residue on clothes. Limescale removers are more aggressive and should be used according to instructions, often less frequently than general cleaners.

Odour and Mould Eliminators

These cleaners often contain disinfectants, such as bleach-based compounds (used with caution) or specialised anti-microbial agents, to kill mould and bacteria that cause persistent foul smells. They target the source of the odour rather than just masking it. When dealing with a genuinely smelly machine, these are often the most effective, though vinegar can also be a potent, natural alternative.

Combination Products

Many modern washing machine cleaners are formulated to tackle multiple issues simultaneously. They aim to descale, deodorise, and clean away detergent residue in a single application. These are often the most convenient option for general maintenance, providing a broad spectrum of cleaning action.

When to Choose a Specific Type

• Persistent Musty Smells: Opt for an odour and mould eliminator, or a strong general cleaner.
• Visible White Residue or Poor Heating: Choose a dedicated limescale remover.
• General Grime and Mild Odours: A good quality general-purpose cleaner or combination product will suffice.
• Eco-Conscious Cleaning: White vinegar and bicarbonate of soda offer effective, natural alternatives for many common cleaning tasks.

Always read the product label carefully, especially warnings about mixing chemicals or using on specific machine types (e.g., high-efficiency or steam models).

Understanding the purpose behind different washing machine cleaning products allows you to select the most appropriate one for optimal results.
