Eucalyptus oil, what can’t it do? There’s certainly a very long list of ways this natural essential oil is useful around the home, and here’s another one to add to it.

We’re going to tell you how to deal with shirt collar stains using eucalyptus oil, and the hack that makes it even simpler.

As we are heading into the warmer weather, with the accompanying humidity and sweat, stains around shirt collars and under shirt arms – particularly white shirts – become an issue again.

What are these stains caused by?
Well it’s mostly sweat, but also dead skin and natural oils can lead to the buildup of that browny yellow stain. If you have long hair or use makeup, any product you use may also come into play.

Eucalyptus Oil stain busting hack
First of all, you need our secret weapon: Bosisto’s Eucalyptus Spray. Bosisto’s Eucalyptus Spray is eucalyptus oil but in a handy spray can, which makes it much easier to apply.

Step 1: Spray Eucalyptus Spray liberally, directly onto shirt collar and underarm stains.

Step 2: Rub the shirt fabric together to rub the oil in.

Step 3: Launder as normal.

For particularly bad or old stains, you can add a soaking step after Step 2. For best results, use an enzyme-based laundry detergent such as Bosisto’s Power Plus and follow the soaking directions on the label.

Why does eucalyptus oil help treat sweat stains?
Eucalyptus oil is a natural grease-buster, and as many shirt stains are caused by a combination of sweat, dirt and greasy body oils, it really helps to
lift those kinds of stains.

Pre-emptive stain busting!
Before you even get out your eucalyptus oil to deal with stains, here’s a few ways to help prevent those ugly yellow sweat marks in the first place.

  • Make sure your neck is clean, and let any hair product properly dry before putting on shirts.
  • Investigate using an antiperspirant on your neck as well as under arms if the issue is quite bad.
  • Catch the stain before it gets bad – when there’s just a hint of discolouration. Then they’re easier to treat and remove.


Follow manufacturer’s directions when laundering garments and always patch test a small area first.

Always read the label and follow the directions for use.
