Anyone? I can't quite face having to throw it out and buy a new one (it is sprung and wasn't cheap), but the smell is TERRIBLE. Basically it is supposed to be used 1 side up only (removable top cover, plastic underneath...), but it got flipped at some point and then wee-ed on maybe 5 times. It is truly grim. I have tried washing it in bath with the usual fairy washing liquid, but it still smells.
Is there is a clever trick that anyone knows of? Please do share it, I'd be so grateful! Thank you.....
