On the advice of a friend of mine who is an expert housekeeper, I wash all clothes on cold or occasionally 30 degrees. She maintains that cold washing is the best thing to get rid of stains and smells, as hot washing tends to fix stains. No problems there, but....
Don't some clothes need to be washed at 60 degrees to disinfect them from dust mites (I'm thinking of bedding here) or other bugs such as snot, body fluids etc. (sorry to be so graphic!)
What do you think?
