Ok here’s something different. Our carafe for our automatic coffee pot has a stainless steel interior, much like a thermos. After about 5 years of daily use the inside was completely stained a dark brown-black and even putting it through the dishwasher did no good.
On a whim, I put one tablespoon of “Stain and Odor Evaporator”, (our Pet and Household stain remover) in the pot, filled it with warm water and left it as we went out for dinner. When we got back several hours later I poured out the solution, rinsed in fresh water and the interior of the pot was brilliantly clean and as shiny as new!!! Just another use for Wash Safe products!!!
