I know I brought this on myself for not being careful. I washed a soiled pee mat, I used disinfectant laundry liquid and powder, it smelled clean so I thought it would then be fine to wash a merino wool dress on the wool setting, it’s my most expensive dress and worth £200, and I don’t have many clothes. I have just washed it and it reeks of piss, I hate myself right now. I’d never washed the dress before it doesn’t retain odours but I had to because I spilled tomato on it
