Help!!! How to clean this please

[Butterfly44]

Wise mumsnetters..Inside washing machine....any solutions I can try? Doesn't wipe off when I try.

I would spray something like Zoflora concentrate or bleach into it then leave it for 5 minutes then try to wipe it off x

I’d worry that bleach might damage the rubber. It needs something mildly abrasive I think, maybe try a magic eraser or a Brillo pad

Would a washing machine cleaner clean it?

Soak kitchen roll or a cloth in milton and leave it to soak

I used some mould and mildew remover on my mums recently. Leave on for 5 and then wipe clean. Completely cleared it.

My go to is 200ml white vinegar, 50ml isopropyl alcohol, couple of drops of dish soap, then topped up to 500ml with water. It cleans pretty much everything.

HG mould and mildew cleaner. It's great.
