I add a cap full of bleach, and a drop of dishwashingliquid to hot water in my sink and soak my dishcloths over night. In the morning the cloths are clean and sanitized and the sink is sparkling and disinfected.
instead of buying tumble drier sheets soak a flannel in fabric softner then squeeze out all the excess fabric softener.then put it on top of your cloths in the drier.
