@cleanthatup: Stinky towels are usually NOT caused by dirt. It is usually detergent buildup and trapped moisture. Most people use way too much detergent, which leaves residue in the fibers. That residue traps bacteria and moisture… and that is what causes that sour towel smell. Here is how to fix it: Step 1: Reset wash Run a hot water cycle with 2 cups of white vinegar and no detergent. This helps break down buildup. Step 2: Wash again Wash a second time with a small amount of detergent (about 2 tablespoons max). More soap does not mean more clean and can leave residue. Step 3: Dry fast Fully dry towels right away. Never let them sit damp in the washer or folded before completely dry. If they still smell: Use a laundry sanitizer to kill odor causing bacteria. Pro tip: Clean your washer and dryer too. Dirty machines can make clean towels smell bad. Clean towels do not need to smell strong. They just need to be clean, free of buildup, and completely dry. Save this for your next laundry day.
