- Sprinkle baking soda on top and rub it all in with a brush

Stubborn sweat stains — those gross, yellowish patches that can develop around under-arm seams — can ruin otherwise perfect white T-shirts.
Luckily, a popular lifestyle blogger has revealed her surprisingly easy trick for getting them out — and it only requires four things.
Utah-based author, blogger and mother-of-four Jill Nystul shared the simple and effective how-to on her blog, One Good Thing, breaking down how Dawn dish soap, hydrogen peroxide, baking soda, and a scrub brush or toothbrush are all you need to make your white tees as good as new.


Before and after: Utah-based author and blogger Jill Nystul shared the simple and effective trick for removing sweat stains
Jill came up with the trick not long after her two sons joined a church basketball league and started tossing much dirtier shirts in the hamper.

The expert: She shares helpful tips on her blog, One Good Thing
'Their white undershirts took on yellow sweat stains at the armpits that just wouldn’t budge, no matter what I tried!' she said. 'I even tried pouring straight bleach on the stains at one point, and still, those stains stayed put. But I was determined to find a solution to those stubborn stains!'
Eventually, she found this method on the internet and went on to share it with her fans.
First, stir one part Dawn dish soap with two parts hydrogen peroxide. Apply it to the stain, and then sprinkle baking soda on top.
Rub the mixture in with a scrub brush or toothbrush, covering the whole area.
After letting it sit for at least an hour (but up to a whole weekend), launder the shirt as usual — and voila, good as new!

Ta-da! After that, launder the shirt as usual and the stains should come right out
The method is backed up by science, too. Baking soda, hydrogen peroxide, and Dawn dish soap are all popular cleaning agents in their own right, and combining them in different combinations can boost cleaning power.
Jill also offers plenty of other helpful cleaning tips on her blog.
For ink stains, she recommends blotting hand sanitizer onto the stain and leaving it for 60 seconds before washing. The high alcohol content will cut through the grease and help remove it.
For oil stains, she suggests blotting the oil spot with a dry napkin before sprinkle it with baking soda, which will absorb the oil. Finally, brush the powder off and launder as usual.
Other tricks include blotting lipstick stains with white bread, rubbing grass stains with salt and lemon juice, and using a combination of baking soda and hydrogen peroxide on stained baking trays.
