How to clean a soup maker - and the one thing you should NEVER do, according to experts
Say goodbye to tomato soup stains


Many of us would happily eat soup every day of the year, but there’s no denying that autumn and winter are prime soup-eating seasons. And while soup makers are a great way to ditch canned supermarket soups in favour of the homemade kind, you also need to know how to clean a soup maker to keep the deliciousness coming.
Whether you’re on the smooth or chunky side of the spectrum (I prefer a smooth soup, personally), the best soup makers will help you bring your favourite flavours to life. But a dirty soup maker can contaminate your food and even result in stubborn staining, ultimately affecting the appliance's efficiency in the long run, so you need to know how to get it squeaky clean ready for the next soup.
As Isabella Forgione, small appliances expert at AO.com, explains, ‘Cleaning your soup maker properly can help maintain its performance and extend its lifespan, so it’s best to know how to clean it.’ We’ve put together the ultimate guide on how to clean a soup maker, so you can keep those soups coming all winter long.
What you'll need
Step-by-step
1. Make use of the self-cleaning function, if available
Sometimes, cleaning a soup maker is incredibly easy, thanks to the extra bells and whistles that come with more modern appliances. And while this isn’t the case across the board (especially if you have an old soup maker), you may be able to use a self-cleaning function.
This time-saving function allows you to push a button and have the appliance do the hard work for you. Charles Cadman, Product Developer at Salter, says, ‘The Salter Digital Soup Maker features a ‘Blend/Clean’ function to remove stubborn stains. Simply add hot water to the stainless-steel jug to the max line and select the cleaning function.’
However, if your soup maker doesn’t have a self-clean option - or you think it needs an extra helping hand to be 100% clean - you can follow the steps below.
2. If not, switch it off and let it cool down
If you’re going to clean a soup maker with your own two hands, your first step is to ensure that it’s safe to do so. After all, you don’t want to burn yourself - and we all know that electricity and water don’t mix.

That’s why Charles advises, ‘Before cleaning your soup maker, ensure your appliance is switched off, unplugged and has cooled down after use.’
It may take a little while for your soup maker to cool down, but it’s important to be patient and wait until it’s cool to prevent any accidents.
3. Fill it with warm water and washing-up liquid
When your soup maker is turned off and cooled down, you can then start cleaning it. Thankfully, this is very easy to do.
Isabella says, ‘After each use, fill your soup maker’s jug with warm water and a drop of washing-up liquid. Wash this with a soft sponge and pay special attention to avoid submerging any electrical parts in water.
We cannot stress this strongly enough. Submerging it is the one thing you should never do when cleaning a soup maker, as doing so will damage and potentially break the appliance's electrical components. Then, you’ll have to buy another one.
4. Tackle tougher stains
Although the above steps should be enough to get rid of tomato stains or the last few remnants of blue cheese, there’s always a possibility that you may be greeted with more stubborn stains in your soup maker. If that’s the case, you just need to repeat the process - but be a little more patient.
‘Repeat the same process, but allow your soup maker to soak for half an hour,’ says Isabella. ‘Avoid using any metal scrubbers and harsh chemicals like bleach. Finally, be sure to clean the blades, but do so carefully with a small brush.’
In fact, it may be worth using a soft toothbrush (a clean one, of course) to ensure you don’t damage the blades or your fingers in the process.
If your staining is from the hard water in your area, you may also need to descale your soup maker. To do this, you can clean with vinegar. Simply fill your soup maker with some white vinegar and leave it to work its magic for 30 minutes. Make sure you rinse afterwards - unless you want your next soup to have a vinegary twist!
5. Dry and store for future use
When you’ve completed the above, you can then dry your clean soup maker with a clean tea towel - but don’t put the lid on back yet. Experts advise storing your soup maker with the lid off as this allows any residual moisture to evaporate. This will ultimately prolong the life of your soup maker and prevent the build-up of mould.
Then, you can store it wherever you’d like - no matter whether you want to store it on the worktop in your kitchen, pop it away in a kitchen cupboard, or store it in your utility room with other small appliances.
Just remember to repeat this process after every use to keep it as clean as possible.
FAQs
How to clean a burnt soup maker bottom?
If you’ve burnt your soup in your soup maker, soaking it in a mixture of warm water and washing-up liquid for 30 minutes should lift the burnt residue from the bottom.
If that still doesn’t work, you can try the same thing again but use white vinegar instead of the washing-up liquid. The acidity of the vinegar should dissolve the stubborn residue - but you may need to give it a slight scrub with a brush to get it off completely.
If that still hasn’t done the trick, make a paste of baking soda and warm water before cleaning the bottom of the soup maker. However, this should be a last resort as the baking soda can sometimes be too abrasive for the appliance.
What not to put in a soup maker?
Although a soup maker can whip up everything from a broccoli and stilton soup to a butternut squash soup, there are some foods and items you should never put in a soup maker. This includes:
- Shop-bought soups.
- Raw meat.
- Frozen vegetables.
- Tough herbs.
- Large chunks of food.
