What Causes Yellow Sweat Stains?
Many people assume that sweat itself is solely responsible for these yellow patches, but the reality is slightly different. The stains form when the salts and minerals present in sweat react with the aluminium compounds commonly found in deodorants and antiperspirants. Over time, this reaction creates yellow discolouration on the fabric, which can gradually become more noticeable and difficult to remove.
Hydrogen Peroxide, Baking Soda Can Help
One of the most effective ways to treat yellow stains on white clothing is by using a mixture of hydrogen peroxide and baking soda.
To prepare the solution, combine one-quarter cup of hydrogen peroxide with one-quarter cup of baking soda and add a small amount of water to create a thick paste. Apply the mixture directly to the stained area and gently scrub it using an old toothbrush or a sponge.
Allow the paste to sit on the fabric for around 30 minutes so it can work deep into the stain. Once the time has passed, rinse the shirt thoroughly with cold or lukewarm water.

Vinegar And Lemon Can Also Help
If hydrogen peroxide is not available, white vinegar can be a useful alternative. Simply apply vinegar to the stained area, leave it for approximately 30 minutes, and then wash the garment as usual.
Similarly, a paste made from lemon juice and baking soda may also help remove yellow marks. Apply the mixture to the stain, leave it for half an hour, and then rinse and wash the shirt normally.
Important Tips When Washing Stained Clothes
After treating the stain, wash the garment with your regular detergent. Avoid placing the shirt in a dryer until the stain has completely disappeared, as heat can cause any remaining marks to set permanently into the fabric.
Whenever possible, allow the shirt to air dry naturally. If a faint stain remains visible after washing, the treatment process can be repeated.
