How to prevent underarm stains

How to prevent underarm stains

There’s nothing sexy about pesky underarms stains, yet how many times have you caught sight of yellow rings or crusty white marks in your armpit area? Embarrassing!

But hey, it’s okay. It happens to the best of us and, thankfully, where there’s a will there’s always a way – of banishing underarms stains for good. Yeww!

First up, let’s talk prevention…


Stopping stains is sometimes as simple as tweaking your daily routine. Start by making sure your armpits are totally dry before applying your deodorant. If you’re using a liquid deodorant you can also try waiting a while (until your deo is dry) before getting dressed. That can help too.


Forget over-zealous application. You don’t need to apply a bucket full of deodorant to stop sweat and banish BO. We recommend using a pea-sized amount ofWoohoo All Natural Deodorant Paste and don’t forget to rub it in (until is disappears completely). This will help keep the formula off your clothes and reduce the likelihood of underarm stains. Make sure you wash all Woohoo off when you shower so you don’t get any build-up.


Ditch your aluminium-based anti-perspirant. Harsh? Perhaps, but while we know aluminium is bad (blocks your sweat ducts) it can also react with sweat to produce those darned yellow stains we’re trying so hard to get rid of.


If using a deodorant paste, be sure to warm the paste between your fingertips before applying. This helps to ensure smooth, consistent coverage, which reduces the need to re-apply throughout the day. The long and short of it is—fewer re-applications, less chance of it ending up on your favourite tee/shirt/blouse.

Woohoo fan application tip #1 - Vicky tells us her favourite way to apply is to put a pea sized amount of Woohoo under her armpit and let it melt while she does her skincare routine, and then rub it in. Super smooth, awesome coverage every time. Love it!

Woohoo fan application tip #2 - Try putting your Woohoo on at night before bed instead of in the morning.

Let’s talk stain removal

If your best prevention efforts fail, fear not—we have a few stain removal methods up our sleeve.

Soda Super Hero

Meet your new stain-fighting friend Baking Soda. Make a paste with baking soda and water and apply to the stain. Allow it to sit for a couple of hours. Pop some laundry detergent on the stain and rub it in. Shove it in the washing machine and say goodbye to your underarm stains.

Peroxide Power

Grab a bottle of hydrogen peroxide from your local pharmacy or supermarket. Make a paste with 50/50 hydrogen peroxide and water and apply it to the stain. Go grab a cuppa. When you get back, chuck the garment in the wash as usual.

Wage an Aspirin Attack

No, we’re not talking about you taking a couple of aspirins and pretending the stain doesn’t matter. Crush 5 aspirins and dissolve in a couple of litres of hot water. Soak your clothes for 4-8 hours (depending how bad the stain is). Next up, add in your usual laundry detergent and massage the clothes. Hurl the garments in the washing machine and voila!

Smell ya later, underarm stains.
