1) Soak in distilled white vinegar and hot water for 30 minutes to over night. This will get rid of any funk issues you may have lingering even after a normal wash, especially stink caused by wiping up dairy messes, ask me how I know, lol! 2) Boil for about 10 minutes. If this step scares you you can bring the water to a boil, turn the heat off, then put the cloths in and let them sit in the hot water for 20-30 minutes. 3) Then they are ready to go into the washing machine! Use a detergent that is free of fillers and dyes. 4) Toss in the dryer. DON’T put any dryer sheets in because they will clog your little microfibers! You also have the option to hang them up to dry.
