Making Sure Clothes Are Really CleanHi. I wondered if any other readers have any ideas for making sure that their laundry is not only washed, but also disinfected. I had been using cold water and detergent for colors, and warm water for whites--until I began working at a local hospital. I want to make sure that I'm killing any harmful microorganisms that are on my clothes when I get home. I have started using hot water with bleach for my whites, which should help--but can anyone give me any tips for colors (what water temperature, best kind of detergent, etc.). Any suggestions will be appreciated.
