Want to wear white this summer but need to keep it white... Here are a few tips.
Polyester is a breathable and stretchy fabric, which makes it great for sports and athletic wear. White polyester can make your sports gear stand out, on a team or even on the road at night, but it can also start to yellow and look dirty after many uses. Keeping white polyester sports clothes clean is easy with a few extra steps when washing them.
We have a few another tips
For an unwanted stain.
You need fairy washing up liquid. ON DRY fabric pour a small amount of fairy directly on to the stain. Let the green liquid soak in for a few minutes (time it!). Then rinse the stain (without rubbing the fabric) with cold water.
This should lift the stain. Then follow the instructions above.
Don't sweat it. Those yellow stains in the armpits and around the collar of your favorite white T-shirts aren't a sign that you're sweating too much or not cleaning properly.
These areas are just harder to get clean and are made up of more than just old perspiration and dirt.
Undissolved deodorants may be a culprit, too. If you have hard water, the deodorant residue (and soap and perspiration) can't wash out properly. Here is a method for removing those sweat stains
Mix 1 quart water with 4 tablespoons salt. Sponge this mixture onto the stained area, then repeat until the stain disappears. Wash as usual.
