I spent a whole day cleaning the washing machine recently - bra wires, nails, stones & disgusting "gunk" - even the thought of it makes me retch now! There was sludge around the rubber seal thing inside the drum - horrible. Anyway, I cleaned it & rinsed 3 times with dishwater tablets & that sorted it out. We only visit the house every 6 months or so - on agreement with the tenant - so from now on when we do inspect it I'll be paying special attention to the washing machine. Don't even get me started on the cooker! How can people live with that level of dirt?
