My teenage daughter gets yellow stains under the arms of her white uniform shirts. I have tried vinegar, ammonia, lemon and baking soda paste. We have tried different deodorants. Nothing seems to help, so I have had to buy a lot of white shirts over the last three years. Do you know how to get rid of these yellow stains? - Stephanie
Nothing is quite so unsightly as dingy yellow perspiration stains in white garments. Not only are these stains ugly, they can weaken the garment's fabric and harbor odors. Perspiration stains are organic, much like blood and grass stains, albeit more stubborn. Your best results will be with an "enzymatic" laundry product. The enzymes actually "eat" the protein in organic stains.
A laundry pretreatment product for all kinds of stains, especially those that are organic is best. Removing the stain may require some repetition.
If the stain doesn't come out, do not put the garment in the dryer because that will set it. Keep repeating until it comes out. If the stain is very old and has been heat set, you may have no choice but to throw that garment away. In the future, make sure your daughter always wear a good antiperspirant. That will help stop those stains before they get started.
You can find a great Enzyme pre-treatment on my website www.quixtar.com (IBO referral# 3345643). You will find it under categories: home, laundry, pretreatments. It is the SA8® PreWash with Enzymes Liquid Spot Treatment and it only costs $9.45 and will last your forever. I use it all the time and it works wonders. Just treat the underarms when you take the shirt off before you wash it and the stains will not even appear at all.
