Bicarbonate Of Soda – The Best Natural Remedy For Armpit Odour

Body odour is not something I’ve had an issue with for most of my life, however, after hitting 40 years old I’ve suddenly started struggling with armpit odour and it’s so unpleasant. After trying many things I’ve found bicarbonate of soda for armpit odour to be the best remedy.

Bicarbonate of soda for armpit odour

I’ve never had a problem with body odour until recently, even sweating from exercise or heat did not cause problems. Then I turned 40 years old and suddenly I could smell myself almost all the time, even straight after getting out of the shower. Using deodorant didn’t help, I could smell myself through the scent and it was awful.

I spent a lot of time researching remedies online and struggled to find something that worked. I got very frustrated reading information that told me to shower to combat body odour, have botox injections, or use prescription-strength deodorant.

There can be many causes of body odour, the most obvious one being not bathing or showering regularly. It can also be caused by hormonal changes and this is clearly what has happened to me since I’m over 40 and heading towards menopause. Hormonal changes attract more bacteria to sweat and cause us to smell during perimenopause.

Then I found a post that recommended using bicarbonate of soda for body odour and gave it a go. It worked beautifully but not without some trial and error along the way.

Bicarbonate Of Soda For Armpit Odour

Bicarbonate of soda (baking soda) is a fantastic natural remedy for odours, I’ve been using it for years around my home for cleaning. I never thought to try it under my armpits until I read about it online. The skin has natural acids that the bicarbonate of soda can balance out helping to eliminate smells.

However, the methods I read online on how to use bicarbonate of soda for smelly armpits did not work that well for me since I found my skin got quite irritated. The two methods I tried were to mix it with water to make a paste or to mix it with any lotion and apply it. While both of these methods worked beautifully for eradicating odour my armpits got sore and my skin got burnt.

The next thing I tried was applying it straight to my skin in powder form without adding anything and it worked like a charm. No irritated skin and so simple and easy to apply after bathing.

If you try my method and it still irritates your skin I found something that may work for you – before applying the bicarbonate of soda to your skin apply zinc oxide baby bum cream (like Sudocreme) first.

I usually bath or shower at night and every second or third day I use bicarbonate of soda on my armpits afterwards. It works like a charm and is so easy to do.

Other Natural Remedies For Armpit Odour

Tea Tree Oil

Another great remedy I found is to use tea tree oil and it worked incredibly well. I started applying tea tree cream and it got rid of my armpit odour.

The reason why I’m not continuing with tea tree oil is that my husband hates the smell so it causes trouble if I apply it just before coming to bed. I’m also not fond of using it before I go out because while I don’t particularly mind the smell its not my top fragrance choice when going out.

If you use tea tree oil mix it with some water before applying to your armpits.

Apple Cider Vinegar

I’ve read lots of good things about apple cider vinegar for body odour, so I am sure this will be a great remedy to try. Mix it with some water and apply.

Lemon Juice

Lemon juice is another home remedy for body odour I came across during my online searches and it seems there are a lot of positive results. Mix it with water and apply.


Another natural remedy I came across is to make a paste with water and turmeric and apply, then wash off after a while. I have not tried this one because it sounds a little messy and I don’t want to have to have a bath, apply my remedy and then wait a while to wash it off.

If you’ve tried bicarbonate of soda for armpit odour or any other natural remedy let me know how it worked for you.
