Washing machine - how to remove hardened soap powder? (2025 Update) FAQ

Apr 23, 2006 Last reply: 1 year ago 25 Replies

We have a quantity of hardened soap powder (at least, I assume that's what it is) in the soap powder tray, and in the recess it fits into. This is an old Hotpoint.



It's causing problems moving the tray; it's very hard to scrape off. Any useful tips on removing it?



I'd rather avoid the thermic lance...


rub it off with a wet cloth? Run the drawer under the tap?

Ha! If it was that easy, I wouldn't have asked! This stuff seems near insoluble. We're in a hard water area but this is localised to the soap tray.

As an aside, for the Calgon-haters...this machine is nearly 11 years old and I have just changed the (very little scaled) element for the first time. And even then it was only because the rubber seal had failed.

Many powders use fillers like chalk as bulking agents. Hence you may find a descaler or some other mild acid will help remove it. Especially if you can let it soak for a bit.

it in citric acid washing machine descaler. If you live near a Waitrose shop they do their own Ultima brand washing machine descaler for about 2.60 GPP for a 250g packet.

Aha. Thanks...John and Phil.

I have some citric acid here somewhere...was thinking of trying that...

And in future clean it more often and you won't have that problem again ..:-)

I'm relieved to hear it, was worried :)

As a descaler, citric acid is fairly pathetic. Boiling temp and long long immersion times are nedeed to get anywhere. HCL OTOH is instant, and can be bought dilute as some brands of limescale removing toilet cleaner, or not as dilute as brick cleaner. Obivously HCl eats things, so beware of metal, cotton, eye contact etc.

I think after 10 years even lemon juice would have done the job.

I was going to say....I don't even remember asking that!

Too late ... though I think Google are being a bit cruel '-)

I have been known to liven up boring meetings by tapping it with a pen. Not that it's transparent now...it looks much like a poper one.

Do these users of homeownershub only see posts that are over ten years old?

If you still have the transparent one you could do something fun for halloween involving red leds.

That's just the Alzheimer's, nothing to worry about.
