How to Clean Antiperspirant From a Cotton T-Shirt

Although antiperspirant prevents sweat from showing on your clothes, it can leave behind noticeable stains on cotton t-shirts. Deodorant leaves behind stains that are most evident on darker colors. Neglecting the stains can result in a permanent discoloration on your favorite shirt. Instead of discarding it, salvage your t-shirt by treating the antiperspirant stain before you launder it. After you remove the deodorant stain, prevent it from returning to keep your t-shirts clean and attractive.

  • 1/2 cup table salt
  • 1/4 cup hot water

Instructions

    • 1

      Mix 1/2 cup of table salt with 1/4 cup of hot water in a bowl. Dampen a cotton ball in the salt water and blot it over the antiperspirant stain until you remove it completely.

    • 2

      Dissolve any remaining deodorant stains by blotting them with white vinegar. Launder the t-shirt in the hottest water possible. Remove the t-shirt from the washer and examine it for the antiperspirant stain. Do not put the shirt in the dryer because it can cause a lingering deodorant stain to become permanent.

    • 3

      Apply ammonia to tough deodorant stains with a washcloth. Blot the stain instead of rubbing on it because you can cause the stain to spread. Rinse the ammonia from the t-shirt.

    • 4

      Treat the deodorant stain with a commercial pre-wash stain-removal solution. Read the directions on the pre-treatment carefully to prevent damage to the shirt.

    • 5

      Wash the shirt with the hottest water setting possible. Hang the t-shirt to dry and carefully examine it after it dries to ensure that the antiperspirant stain is completely gone.
