Can someone please help me sort my washing machine smell out? I found a rogue toddler sock still dripping wet in the rubber creasing at the front of the washing machine, I hadn't realised it was stuck and it's been there for a few days and the machines stinks now of mould/damp, it's horrid and I just can't shift it! I have done several hot washes, anti bac wipes and left the door open, what am I missing?
