How to prevent sweat stains

When faced with sweat stains, one solution is to use less deodorant or antiperspirant. Some believe that applying a thick layer can help prevent stains by controlling the sweating, but the excess deodorant or antiperspirant will only soak directly into the fabric in the armpit area. It is recommended to allow the deodorant or antiperspirant to fully dry before putting on clothes.

The last resort is to try a new deodorant. You can find one that is aluminum-free or contains less aluminum than other brands. The switch can help prevent perspiration stains. 

Regardless of the preventive methods that you will use, make sure that you will wash or dry clean clothing that has been exposed to sweat immediately. Remember that a fresh stain is easier to remove than a dried one.
