My washing machine has had a bit of a whiff to it on occasion but this morning it definitely has a bad egg smell. I know I've seen on here about doing an empty wash, using ?bicarb of soda (or maybe vinegar?) but am not sure exactly what to do and what not to do...
Can anyone explain in simple words exactly the process to clean it all out please? I know it's going to be revolting, but hopefully worth it!
