Acetic Acid Neutralizing Rinse for Restoring Towel Absorbency and Odor Removal
Rex says
Rex Sterling, Ph.D. · Head of R&D, Clean Report · Meet Rex
"Pouring 1/2 cup of distilled white vinegar into the fabric softener compartment instead of commercial fabric softener strips away mineral build-up, neutralizes sour odors, and leaves towels fluffier and more absorbent."
The science
-
Acid may dissolve mineral residue
Dilute acetic acid can reduce some hard-water deposits and alkaline buildup on towels; it does not remove every cause of odor.
-
Softener buildup has several causes
Detergent dose, rinse quality, fabric softener, and incomplete drying can all affect towel feel and absorbency.
-
Appliance guidance governs use
Check the washer manual before adding vinegar, and never combine it with bleach. A normal wash and thorough drying remain necessary.
Do it right
Half a cup of distilled white vinegar in the fabric softener compartment, with no commercial softener, on a normal warm cycle, then dry fully. Check the washer manual first - some makers restrict vinegar in the dispenser. Never run it in the same cycle as chlorine bleach.
