U can use stain remover from ace or pink stuff and scrub it or take it off completely and wash it if you haven't done so since it's second hand.
We had a bit on ours from when our daughter had it and it's been stored in the loft, we just sprayed it with a baking soda and vinegar then washed it up and it was fine.
Okay thanks guys! 💕
I would risk putting it through a very hot wash with some sanitiser, like Milton. I'd be a bit cautious with mould, personally
Is mold really spelled that way in the U.K.?
@Harriet I know. I feel iffy about it. Because it’s only tiny dots I’m going to see how well I can clean it and go from there…
Soak it in Milton steriliser, then a hot wash with bio detergent
