Top tips on how to remove perspiration stains from a white shirt & other white clothing

When it comes to banishing perspiration stains from your favorite white shirt or clothing, acting fast, applying appropriate pre-treatments and adding oxygen bleach is key.

For fresh yellow stains, the American Cleaning Institute recommends the following steps:¹

1. Act quickly

Don't procrastinate on your laundry duties; deal with sweaty clothes pronto to stop them from turning into stains and sticking around.

2. Pre-treat

If the stain is light, pre-treat it with laundry detergent. If it’s heavier, use a prewash stain remover instead. Leave them on for 5 to 10 minutes before washing.

Always check care labels and perform a small test before applying any solution to ensure it won’t harm the fabric.

3. Add some oxygen bleach

Before you put your clothes to wash, add oxygen bleach – according to the manufacturer’s instructions – and launder. Avoid using chlorine bleach on sweat stains as it can react with sweat stains and give them a yellow tint.²

Other things to consider

Make sure you only wash white clothes with other white clothes – you don’t want any bright or dark colors potentially making the stain worse.
Be patient and pretreat your stains before washing.
Always follow care label instructions to avoid shrinking or ruining your clothes.
