The best deodorant in the world is dirt cheap and more effective than any commercial one pushed by the “beauty” industry. What is it? It’s alum powder.
I can buy alum powder for about a buck for about a pound. (5.5RMB per 500g to be precise.)
That much alum powder will last me several years as a deodorant. Of course I have some added expenses. I need to get a spray bottle, for example. That’s an extra 50 cents and will outlast the alum powder.
You could probably stop here, but hey, let’s splurge and go fancy! Let’s get a funnel and a measuring spoon too!
The small funnel plus all of those measuring spoons adds up to a bit over a buck. Again, these will outlast your alum powder.
So for an initial outlay of $2.50-$3 you have five years of long-lasting, completely scent-free deodorant. (You can also spray gamy clothes with it to neutralize the scent for a few hours.) After that every five years or so you spend a buck to get your next five years’ supply. It is a bit more complicated to use than regular deodorant sprays though. Every two weeks or so you’ll have to measure a bit of the alum crystal into the funnel and wash it down into the bottle with warm water until it’s full, leaving it to sit a while to dissolve.
