Well-meaning relatives gave DD a load of squirty bath toys a few months since. She absolutely loves them and has given them all names so throwing away is a no-no. After every bath I squirt residual water out and leave them propped on their sides to dry.
They are still full of mould inside
one is a pink pig and another a yellow chicken and you can see dark shadows thru the plastic.
Is there any way to soak or clean them to get rid of the mould that won't discolour the plastic?
