@Mightystar - after my own treatment - I thought I'd become quite 'pongy' as well!! I used Gamophen Soap for a while afterwards (I've always loved the smell of it - it used to be considered a 'surgical soap' for sanitising hands before medical procedures - my Dad used to use it in his Dental Practise!)
It should be in chemists & has (what I believe to be) a lovely scent. You used to be able to get it in supermarkets.
I'd always meant to try this home-made Coconut deodorant - but never got around to it. I just used Roll-Ons instead! (Yeah, lazy, I know!)
Maybe give it a go? (I should too!!) All the best xxx
Do it Yourself Coconut Oil Deodorant with just 3 ingredients
(Mixing the coconut oil, cornflour, and baking soda in a bowl. The coconut oil mixes easier when it’s a warm liquid as opposed to a cool solid.)
TIP: If it’s too hard to mix easily, use your fingers, and the warmth of your hands will liquefy it, making it easier to use.
Put the deodorant into a small wide mouthed jar, and take a small amount onto your fingers and rubbed it into your underarm area. In really hot humid temps, it may be soft - but being at room temp in most places, it should be 'firm'
It has a really distinctive sweet Coconut Smell & is popular with those wanting a natural deodorant.
How to make coconut oil deodorant:
Step one: Put the coconut oil (warmed), cornflour, and baking soda in a bowl.

Step two: Stir well to combine.

Step three: Move the liquid to a clean jar for storing.

The verdict
Since coconut oil is a liquid in heat and a solid when cool, the consistency varies upon temperature, but it works equally well regardless. There has been no problems with the oil staining clothes.
There are a million and one variations on this recipe all over the web. Some people use more or less of the ingredients, some people just use coconut oil alone, and some include things like essential oils for fragrance. The coconutty, tropical smell as-is, is best.
Test it on a small area first - as some people complain that the baking soda and/or cornstarch gives them a rash in certain quantities. If you find that, maybe increase the amount of coconut oil.
Here's another one, slightly different ....
