How to Get Rid of and Prevent Yellow Underarm Stains

Do you have yellow perspiration stains on your shirts? This is one of the most common problems that women face! The easiest solution is never let them happen in the first place, but if you have them, we've got some simple at-home remedies to clear them up.

3 Main Causes of Yellow Underarms

You may be asking yourself what causes the yellowing underarm on all your white and light coloured blouses. How is that despite wearing deodorant, you are always having to buy new white shirts.

Perspiration:

Perspiration is mostly water, however it is made up of a small percentage of other things - ammonia, sodium chloride, urea and lactic acid. All of which cause the yellowing and embarrassing sweat stains.

The reaction of antiperspirant and sweat:

Aluminium based compounds, which are commonly found in most drugstore antiperspirants, cause our sweat ducts to swell and blocks the moisture from escaping. With time our sweat bonds with these compounds and chemicals before being released from our body, and as a result as the moisture escapes stains are left in the underarm of clothes.

Fitted Tops and Sleeves:

When moisture and sweat from your body gets trapped between skin and fabric for long periods of time, a build up of bacteria starts to form which creates odours. When this is left on our clothes for too long, damaging stains will appear.
