The other day I made potato and onion rosti (very tasty!!) I squeezed out the liquid from the onions and potatoes using tea towels. I then put said tea towels in the washing machine with a normal load of clothes. Washed as normal. The problem is that the smell from the onions has permeated through to all the other clothes!! I have washed the clothes twice since and they still smell!! Should I try tumble drying them?? A couple of peices can't go in the tumble drier though. What can I do??!!
