I've been using natural deodorants for about 4 years, after really learning the dangers of antiperspirants. I'm not really a sweaty girl, nor a stinky girl, but I do need something to keep the moisture and odour at bay. I've used my fair share of healthier store bought deodorants, they all work for a while, then stop. I've tried the salt crystal, but loose interest very quickly. I've been using baking soda & oil since last summer off and on. Every time I stop, I become frustrated with the breakthrough smell of natural deodorants. I find they cover for half the day, then my natural odour comes through and mixes with the smell of the deodorant creating a not-so-pleasant smell. My natural smell would be better than that mixed crap.
Here is my recipe for perfectly wonderful (cheap) and easy deodorant. If you are sceptical, you can use your regular deodorant as the oil base to start and slowly wean onto just oil.
-Oil of choice; almond, olive, vegetable, coconut etc
I use a combination of olive oil and coconut oil in a small pump container. It is more work than worth it though, because I need to heat the coconut oil in the container before using it. Next time, I'll use coconut oil in a small lid container or vegetable oil in the pump.
-Drop or two of essential oil of your choice, if you'd prefer a smell to your deodorant
-Baking soda (sodium bicarbonate)
After my shower, I pat my armpits dry and add a small amount of oil to them. I then pat on a small amount of baking soda. You really only need a small amount. Done!
You can also make a wet deodorant if you'd like. Mix the above ingredients into a small reusable container with a lid, and apply as needed. I find the dry version with oil first really helps it stay on all day, and keeps me dryer than the wet version.
I've read that some people skip the oil and just use water directly after the shower. I've tried this, and I find it doesn't last all day or make my armpits as soft. I also find the feeling of putting on the baking soda with just water more abrasive than the oil. Personal preference though.
I'm not sure if it makes a difference, but I have lovely bushy armpits. Some women (and men) find they smell more with hair, I find I smell way less. The baking soda stays in place better ;)
Baking soda as deodorant works through high-stress environments for me, hours and hours of labours (forgot at my last birth, big mistake), synthetic t-shirts, and normal sweat. It is very amazing and totally worth a try, since you probably have everything in your house to get started right away.
Using baking soda as shampoo, my entry here.

I just want to say that I have been doing this, as per your directions, for the past few days and I am AMAZED! I had previously been a devote of the Crystal, and in fact pressured other people to try it all the time, but the truth is that I still felt stinky by the end of most days, and with baking soda I am shocked and delighted to report that I think I could skip showering for days and still not stink. It's amazing.
Thanks!

i have a small container of vegetable oil with some tea tree oil in it. i rub that on with my fingers & then my baking soda/corn startch 50/50 mixture. i started using just baking soda with the oil, but found the baking soda itself was bothering my skin so i just switched to baking soda/corn starch 50/50 mixture & i'll see how that works for me.

I'm going to have to try this! I have been using a natural deodorant for a few months, and was starting to notice it wasn't working as well. THEN, I broke out in a HORRIBLE rash. I looked like I had leprosy or something on my arm pits. I gave in and stopped shaving/stopped using deo. Close to a week of no shaving, and 48 hours of no deo, and the rash looks significantly better. So once its all better, I'm going to try this.
