Why Your Washing Machine Needs Regular Cleaning
Over time, washing machines can accumulate detergent residue, fabric softener build-up, limescale, and general grime. This debris creates a breeding ground for mould, mildew, and bacteria, leading to unpleasant odours that can transfer onto your laundry. A dirty drum, seal, and filter can also reduce the efficiency of your appliance, meaning clothes might not come out as clean as they should, and it can even lead to mechanical issues.
Addressing these problems proactively is key to maintaining optimal performance and hygiene. Ignoring these signs can result in persistent smells, reduced washing effectiveness, and potentially costly repairs down the line. Fortunately, a simple and potent solution is readily available: soda crystals.
Soda crystals, chemically known as sodium carbonate, are a powerful yet accessible cleaning agent. They are excellent at breaking down grease, lifting dirt, and tackling limescale, making them ideal for a deep clean of your washing machine. Their alkaline nature helps neutralise acidic odours and dissolve detergent gunk that regular washing cycles might leave behind.
This article will walk you through exactly how to use soda crystals to clean your washing machine, ensuring your appliance stays fresh, hygienic, and performs at its best for years to come. We’ll cover the preparation, the cleaning process, and how to deal with common issues you might encounter.
- Soda crystals are effective for breaking down residue and odours.

- A clean machine improves washing performance.
- Using soda crystals is a simple maintenance task.
Preparing to Clean Your Washing Machine
Before you begin the cleaning process, a few preparations will ensure you can tackle the task efficiently and safely. While soda crystals are generally safe for washing machine use, understanding the prerequisites helps avoid common pitfalls.
First, ensure the washing machine is empty. You will be running a hot cycle, so there should be no clothes or laundry inside. Check the machine’s manual if you are unsure about specific cleaning recommendations or any contraindications for using alkaline cleaners like soda crystals, though they are widely recommended for this purpose.
Gather Your Supplies
You will need:
- Soda crystals (typically 1-2 cups, or follow product instructions)
- A measuring cup
- A cloth or sponge for wiping
- Rubber gloves (optional, to protect skin from prolonged contact)
It is also a good idea to have your washing machine's user manual handy, especially if you are unsure about locating specific components like the filter or detergent drawer.
The most crucial step before starting is to ensure the machine is empty.
Consider the washing machine seal. This rubber gasket around the door can trap moisture and debris. It’s often a prime spot for mould and mildew. You can give this a preliminary wipe-down with a damp cloth, perhaps with a little diluted vinegar or mild soap, before proceeding with the main soda crystal clean. This targeted approach helps remove visible grime before the main cycle.
Step-by-Step Guide: Using Soda Crystals
Now that you have prepared your machine and gathered your supplies, it’s time to get cleaning. This process is designed to be straightforward, targeting the internal workings of your washing machine to remove build-up and eliminate odours.
Step 1: Add Soda Crystals
There are two primary methods for adding soda crystals to your washing machine:
- Directly into the drum: For a thorough deep clean, pour approximately 1 to 2 cups (around 200-400g) of soda crystals directly into the empty washing machine drum. This allows the crystals to dissolve and circulate freely throughout the machine’s interior during the cycle.
- Via the detergent drawer: Alternatively, you can add the soda crystals to the main detergent compartment of your washing machine’s drawer. Use the recommended amount as per the soda crystal packaging, typically around 1 cup. This method can also help clean the drawer itself and the initial wash path.
Refer to the soda crystal product packaging for the most accurate quantity, as formulations can vary slightly. Using too much is generally not harmful but is wasteful; too little might not be effective.
Step 2: Run a Hot Wash Cycle
Once the soda crystals are added, select the hottest possible wash cycle available on your washing machine. A temperature of at least 60°C (140°F) is recommended, as this high heat is most effective at dissolving grease, breaking down detergent residue, and killing bacteria and mould spores. A cotton cycle or a specific drum clean cycle, if available, is ideal. Ensure the cycle runs to completion.
The high temperature is vital for dissolving the soda crystals and maximising their cleaning power.
Step 3: Check and Clean the Filter
After the hot wash cycle has finished, it’s time to address the washing machine filter. This component traps lint, hair, coins, and other debris, which can cause blockages and unpleasant smells if left uncleaned. Locate the filter, usually behind a small flap at the bottom front of the machine.
Place an old towel or shallow tray underneath the filter housing to catch any residual water. Slowly unscrew the filter. Carefully remove any debris, rinse the filter under running water, and then screw it back into place securely.
Step 4: Clean the Detergent Drawer and Seal
While the machine is clean from the hot cycle, take this opportunity to thoroughly clean the detergent drawer and the door seal. Remove the detergent drawer if possible and wash it in warm, soapy water, using an old toothbrush to scrub away any stubborn residue. Rinse and dry it completely before reinserting.
Wipe down the rubber door seal with a damp cloth, paying attention to any folds where mould or grime might be hiding. A slightly diluted vinegar solution can be effective here if mould is present, but ensure you rinse thoroughly afterwards with plain water.
Verification and Troubleshooting Common Issues
After completing the cleaning process, it’s important to verify the results and address any lingering issues. A successful clean should leave your washing machine smelling fresh and looking visibly cleaner internally.
Verification: What to Look For
Run a short, empty rinse cycle or a quick wash with no detergent. Listen for any unusual noises, and check the drum for any remaining residue. The primary indicator of success is the absence of musty or sour smells emanating from the machine or transferred onto clothes during the next wash.
The absence of unpleasant odours is the main sign your washing machine is clean.
Inspect the detergent drawer and seal again; they should be free from visible grime and mould. If you notice a significant improvement in how clean your laundry appears, that’s another positive sign.
Troubleshooting: Persistent Smells
If a smell persists after using soda crystals, your washing machine may have a more stubborn build-up or a specific component requires attention. Here’s what to do:
Residue in the Drum or Pipes: If you still detect a faint odour or see minor residue, you can repeat the soda crystal cleaning process. Ensure you are using the hottest wash cycle available. For particularly stubborn limescale or detergent build-up, a dedicated washing machine cleaner, such as those from Calgon, Dettol, or Dr. Beckmann, might be more potent. These products often contain specific agents to tackle tough grime or limescale.
Blocked Washing Machine Filter: If the smell is accompanied by drainage issues or the machine is not spinning effectively, the filter might still be partially blocked, or there could be a blockage further down the drainage system. Thoroughly cleaning the filter as described in Step 3 is crucial. If the issue persists, a professional might need to inspect the drainage hose or pump.
Issues with the Seal or Drawer: If mould or mildew is deeply ingrained in the rubber seal, it might require more intensive cleaning. A soft brush dipped in a bleach solution (use with extreme caution, ensure good ventilation, and never mix bleach with other cleaners) or a specialised mould remover might be necessary. For persistent issues with the seal, replacement might eventually be required. Ensure the drawer is completely dry before reinserting it to prevent new mould growth.
Why Does My Washing Machine Smell? Often, the smell is due to the build-up of bacteria and mould in damp environments. Regularly cleaning the seal, leaving the door ajar between washes to allow ventilation, and running hot washes with a cleaner like soda crystals are key preventative measures. If the problem is frequent, consider using a washing machine cleaner that contains agents to combat limescale and detergent build-up, or even switching to a liquid detergent which tends to dissolve more readily than powders.
Preventative Maintenance for a Fresh Washing Machine
The best way to keep your washing machine smelling fresh and running efficiently is through consistent preventative maintenance. By incorporating a few simple habits into your routine, you can significantly reduce the need for deep cleaning and extend the lifespan of your appliance.
Leave the door and detergent drawer ajar between washes. This simple step allows air to circulate, drying out the interior and preventing the damp, warm conditions that mould and bacteria thrive in. Ensure no small items are lodged in the seal that could prevent the door from closing fully if you choose to leave it slightly open.
Use the correct amount of detergent. Overdosing on detergent, especially with high-efficiency (HE) machines, can lead to excessive suds and residue build-up. Always follow the manufacturer’s recommendations for your specific detergent and washing machine model. Consider using liquid detergents, as they tend to dissolve more completely than powders, especially in cooler wash cycles.
Run hot washes regularly. Aim to run at least one hot wash cycle (60°C or higher) per week, ideally with laundry that requires it. This helps to kill bacteria and dissolve any detergent or fabric softener residue that may have accumulated. If you primarily wash at lower temperatures, a monthly hot wash with soda crystals or a dedicated washing machine cleaner becomes even more critical.
Clean the washing machine filter monthly. This small but vital component collects lint, coins, and other debris. Regular cleaning prevents blockages, odours, and improves drainage. If your machine has a specific drum clean cycle, use it according to the manufacturer’s instructions, usually once a month.
Wipe down the seal and door after each wash if possible. A quick wipe with a dry cloth can remove excess moisture and prevent mould from forming. For a more thorough clean, a damp cloth or a specialised washing machine seal cleaner can be used weekly or bi-weekly.
By integrating these practices, you minimise the build-up of grime and bacteria, ensuring your washing machine remains a hygienic appliance that delivers clean clothes with every cycle.
