With sweat comes armpit stains, a reality from which no wearer of white shirts is safe. But there's hope yet for the sad, yellowing, under regions of your favourite white T-shirts!
Here's a genius way to banish those unwanted pit stains, using baking soda and hydrogen peroxide.
Using a combination of the peroxide and soda - a small amount of soap can also be added - you'll have sparkly whites that will make you want to throw your hands up in the air all day long. The Huffington Post has the exact amounts for you to follow.
For a coloured shirt, make a paste by mixing baking soda and warm water. Coat the stain and work the mixture into the shirt. Let it sit for 30 minutes, rinse, and wash the item as you normally would.
The secret to removing annoying sweat stains - and all obnoxious stains, for that matter - turns out to be pre-treating, or soaking or scrubbing the clothing item before putting it in the washing machine.
For example, scrubbing grass stains with two parts water and one part white vinegar will lift them from fabric. And letting lemon juice soak into a sweat stain works wonders, too.
Pre-treating also works on condiments, dirt, juice and even ice cream stains.
