Many many moons ago it was customary to boil clothes and linens.My job as a kid was to lug buckets of water from the well,and fill a copper wash boiler on the stove.It was brought to a boil and the linens,ie sheets,under wear ,all whites etc were put in the boiling water.Then they were rinsed in hot water then wrung out and if the sun was out,they were hung out on the clothes line,or spread out on the grass to sun bleach.This I realize is not possible today as most fabrics are synthetic and will not suffer hot water.The laundry detergents today are designed primarily for cold/warm water washing,and do not give the sanitizing effect of boiling. I use CS in the washing machine to take care of the pathogens,etc,but, for any thing like dust mites ,I use a powerful vacuum with good filtration,which is not 100%,but reasonably good.
