How to Remove Stubborn Sweat Stains from White T-shirts: An Effective Method

Removing stubborn yellowish sweat stains from white clothing can be a persistent challenge for many.

These stains typically form due to the natural salts, proteins, and fats expelled by the body, which react with aluminum or zirconium compounds found in antiperspirants and deodorants. This chemical reaction, combined with body heat, causes the yellow discoloration and can leave the fabric feeling stiff.

Lucía Lipperheide, a Spanish content creator specializing in cleaning and lifestyle tips, shared an effective two-formula method on her Instagram account to tackle these difficult stains, particularly on collars and underarms.

The first formula requires 500 milliliters of hot water, one tablespoon of potassium soap, and a small soft-bristled brush. Apply this mixture to the stains and gently scrub with the brush. Let it sit for 30 minutes.

The second formula involves one tablespoon each of baking soda, hydrogen peroxide, and dish soap, along with lemon juice. Apply this mixture to the remaining stain using a metal spoon and let it work for one hour. After this, rinse the garment and wash as usual. It is crucial to dry the clothing away from direct sunlight to prevent further yellowing. Lipperheide also advises against using heat from an iron on these stains, as it can set them deeper into the fabric, and cautions against using chlorine bleach, which can worsen the discoloration. For prevention, she recommends ensuring deodorant is completely dry before dressing and washing clothes promptly after each wear.
