My daughter has had an accident at nursery and weed on her CICA trainers. I have tried to get the smell out (antibaterial spray, febreeze spray etc) but they still smell of wee. Can I put them in the washing machine? I would have thought not - the leds will probably stop working? Has anyone got any other ideas - they cost nearly £30 and we have only had them for about 10 days. Thanks very much.
