Just that really, I've just gone upstairs and balked at the rancid stench of piss, wondering where it was coming from, it was the wash basket.
Turns out when Dh took ds2 swimming yesterday he took the best two bath sheets in the house, then put them on the (piss soaked) changing room floor to dry their feet 
Then to make matters worse left them in a carrier bag in the boot of the car overnight and all day, and has just tipped the bag out into the wash basket.
I've thrown them (and everything they've touched) into the machine with bio washing powder on a 90 cycle. Will this be ok or shall I just burn them????
