Have you ever asked yourself “Why do I have yellow underarm sweat stains on my white undershirts?” Even if you don't sweat a lot, aluminum from your antiperspirant will build up and cause these nasty yellow stains. With a few household ingredients you can remove most stains and prevent new ones from occurring. The following are a few tips on how to wash those nasty yellow stains out of your undershirt.
- Once you notice perspiration stains, you need to treat them immediately. As soon as you've noticed the stain, run the affected area under the faucet using cold water, after you've removed as much surface stain as possible, rub the fabric together. The cold water washes away the acidity left behind by your antiperspirant. To prevent yellow armpit staining in the laundry hamper run cold water over the armpits of your undershirt before the yellowing even appears. This way, they don't sit and yellow in the laundry hamper.
- Refrain from drying your clothes with the perspiration stain, or you may never be able to remove the stain completely. Running your clothes through a washer and dryer cycle can hard-set the stains, making it much more difficult to remove them
- Use RIt dye white wash to brighten up dull, yellowing undershirts (not yellow pit stains).
- Add a cup of vinegar to whiten up an undershirt. This will not remove yellow pitting but will brighten up the shirt.
- Treat underarm yellowing with hydrogen peroxide and Arm and Hammer baking soda. Mix one part water, one part hydrogen peroxide, and one part baking soda, apply the mixture to the stains and allow it to sit for 30 minutes. The longer it sits, the better it will work. Use a toothbrush to gently work the mixture into the stains. Wash the undershirt in cold water as usual, with detergent.
- Wear an undershirt ONCE; wash it before you wear it again.
- Discoloration may occur because your shirts are probably a mix of cotton and polyester or another fabric. You cannot use bleach on these fabrics. Read the label and follow the recommended washing instructions
- To prevent yellow underarm stains choose an antiperspirant with low aluminum content.
- Apply a thin layer of deodorant or antiperspirant and allow it to dry before getting dressed
- For addition protection against yellow armpit staining wear Advadri sweat shields.
- For more cleaning tips go the website of Arm and Hammer.
Eventually your undershirts will wear out, to extend the life of your undershirt follow some or all of the above tips.
