It’s easy to make those telltale sweat spots disappear if you know what to use on them.
Step 1: Pretreat underarm areas Always gently rub a little liquid detergent into the underarm areas of shirts before washing, as a preventive measure.
TIP: To prevent the sweat buildup that leads to stains, wash your tops in the hottest water they can stand every third or fourth time you launder them.
Step 2: Dissolve stains If you see a stain, skip the detergent pretreatment and sponge the area with white vinegar or ammonia instead. Then launder as usual.
TIP: Tackle perspiration stains as soon as you notice them. If left untreated for several days, they may become permanent.
Step 3: Treat fresh deodorant stains For fresh underarm stains caused by a mix of sweat and deodorant or antiperspirant, mix one part commercial spot-treatment with two parts warm water and sponge it onto the dry fabric. Let it sit for 10 minutes, then rinse with cold water. Repeat as needed.
Step 4: Tackle dried-on spots If the deodorant stain is dried on, place the item, stain-side down, on a clean, absorbent cloth and sponge diluted spot-remover onto the reverse side of the fabric. Let it dry, rinse thoroughly, and repeat as needed.
Step 5: Wash in hot water When you’ve removed as much of the stain as you can, gently rub some liquid detergent into the stain and wash in the hottest water safe for the fabric.
FACT: Perspiration itself is odorless. It’s the combination of bacteria on the skin and sweat that produces a bad smell.
