Question: is borax good for towels?
Answer: For a bathtub, we recommend ¼ cup borax, ¼ cub washing soda, and ½ cup detergent. Stir to dissolve. Completely submerge your towels in the mixture and soak until the water has cooled, which usually takes four to five hours. Stir occasionally to help coax out all the buildup in the towels.
