How to Clean a Washing Machine

Washing machines can end up full of nasty smells, dirt, and bacteria over time.

All the mud, food, and pet hair that your clothes pick up will end up in the washing machine, and this can have an impact on how it performs. Fortunately, this can be rectified with a deep clean.

1. Clean the detergent drawer

The first step when it comes to cleaning a washing machine should always be to tackle the detergent drawer.

The drawer is usually home to a build-up of excess detergent and fabric softener, and this residue attracts mould and bacteria.

Take the draw out (if possible), spray with an antibacterial cleaning spray and scrub it well. Rinse with plenty of water and dry before putting it back in the machine.

If your washing machine drawer seems to be prone to a build-up of old detergent, try to rinse it out regularly to prevent it causing a problem.

2. Clean the filter and seal

After tackling the drawer, you need to clean the seal around the door and all the filters.

The door’s seal and the filters will collect any lint, dirt, coins, hair clips, and anything else that was caught in your clothing when you put it in the washing machine.

If left alone, this will create an ideal environment for bacteria, and foreign objects such as hair clips or coins can clog the filter and stop the washing machine from draining too.

Take the filters out, and remove any odd objects that have gotten caught. Rinse the filters well, and put back in the washing machine. Wipe the seal well, checking inside the folds to make sure there are no foreign objects or other nasties caught inside.

Like with the detergent drawer, you should clean the filters and door seal regularly.

3. Use a washing machine cleaner

Once you’ve cleaned the detergent drawer, filters, and door seal, you can run a maintenance wash to clean the inside of the washing machine.

A washing machine is full of nooks and crannies where dirt and bacteria can hide, and the only way to get to it is to use a washing machine cleaner in an empty wash.

The washing machine cleaner will tackle bacteria, mould, dirt, and limescale on the inside of the machine.

To get the best results, you should run an empty maintenance wash once a month, and use a washing machine cleaner at least every 2 months.

If you live in a hard water area or wash a lot of very messy clothing, you might need to do this more frequently.

4. Check the wastewater pipe

If you have cleaned the washing machine well and it still smells bad, the washing machine’s wastewater pipe might be blocked. If it looks like this is the case, use a drain unblocker to tackle the issue.


Keeping the Washing Machine Fresh in Between Cleans

Without care, a well-used washing machine can quickly end up smelling and being dirty again in between washes. By following these tips, you can keep your washing machine as clean and fresh as possible in between maintenance washes.

1. Leave the door open

At the end of a cycle, once you have taken the laundry out, leave the main door and detergent drawer propped open.

This will allow air to circulate, which will encourage the surfaces of the washing machine to dry. This stops the water going stagnant, and gets rid of the damp, cool environment that helps bacteria thrive.

2. Empty the washing machine quickly

For the same reason as above, you should always take damp laundry out of the washing machine as quickly as possible after the end of the cycle.

If you let it sit in the drum, not only will the laundry start to smell, but the inside of the washing machine will too.

3. Use less detergent

Once of the biggest problems on the inside of a washing machine is caused by detergent residue. By using the recommended amount of detergent for your machine and water hardness, you will reduce the amount of residue left behind.

If you use too much detergent or fabric softener, it may not dissolve properly in the water during the cycle. If this happens, the detergent will build up inside the washing machine, causing blockages, foul smells, and giving mould the chance to grow.

4. Wash on hot every now and again

Modern households will usually wash their laundry on cool or cold cycles. This is good for the environment; however, it does not kill the bacteria inside a washing machine.

Every now and again, try to run a cycle on a higher temperature. This will tackle the bacteria build up in the washing machine before it starts to cause a problem.
