I want to disinfect and super clean/whiten my white bath towels. How long can they soak, maximum, without hurting the towels?
For your towels, I recommend a bleach soaking solution of ¼ cup Clorox® Regular Bleach2 per 1 gallon of cool water for 5 minutes. Soaking, dripping towels can be messy, so to avoid splashing the bleach solution on yourself and around your laundry area, use your clothes washer to do the soaking (which will work best in a top loading washer). Be sure to mix up the bleach solution first and then add the towels: select a “small” load size and fill the washer with water, stopping the cycle when it finishes filling. Next, add the bleach, and finally the towels. Note that a typical “small” load setting holds about 12 gallons so you’ll need to add 3 cups of bleach to make the bleach soaking solution. After 5 minutes, advance the dial of your clothes washer so that it drains, then reset the dial back at the beginning of the wash cycle and let it run all the way through so the towels essentially get two rinses. If you want to soak a large number of towels, just select a larger load size; a typical medium load holds 14 gallons (use 3 ½ cups bleach) and large holds 16 gallons (use 4 cups bleach).
