How To Get Sweat Stains Out Of Clothes In 4 Quick Steps

Even though we live in a relatively cool climate we still all sweat. Whether it's from doing exercise, feeling nervous, or the sun deciding to come out for a change, we have all had sweaty smelly clothes at some point in our lives.

Luckily it's pretty easy to remove sweat and body odour from clothes once you know how.

Read on to find out why sweat leads to yellow stains, why our body odour smells, and how you can tackle both of these problems.

Why Does Sweat Turn Clothes Yellow?

You may be surprised to learn that the sweat is not the reason your garments turn yellow in the armpit region.

Well, sweat is partly to blame, but it's actually because of the antiperspirant you wear to try and avoid sweating that you get the yellow patches - ironic much?

Antiperspirant contains aluminium which aims to stop you sweating by blocking your pores. However, there is only so much sweat the aluminium can hold back before the sweat runs, taking the aluminium with it and onto your shirt armpits.

There are some alternatives to antiperspirant, such as just deodorant, if you're tired of treating yellow stains. This is not a popular options as many would rather deal with yellow stains than sweaty armpits on a daily basis!

Why Does Body Ordour Smell?

We have sweat glands all over us to help us regulate our temperature. It's an essential and important function of our body.

Unfortunately, not all sweat glands are the same, and some of them secrete liquids which go on to smell.

Eccrine sweat glands release sweat that is primarily made of water and is pretty odourless, these are found all over our body.

Apocrine sweat glands are found in specific areas of the body, for example, your armpits.

Apocrine sweat glands release lipids and proteins. These lipids and proteins don't actually smell. The smell is caused by the bacteria that live in your armpits feasting on the lipids and proteins which releases an unpleasant odour.

Now you know the reason for the smelly garments you discover when doing the "sniff-test", read on to learn how to tackle it!
