I was using Desitin ointment for some time for chaffing. One day I get the idea to add some Tea Tree Oil to make it a deodorant. I like these GoTubbs as they are great for traveling and make all three at once, which gives me about 6-8 week supply.
Disclaimer: do this at your own risk. Made sure you will not have a reaction to ingredients.
Step 1: What You Need:
Tea Tree Oil
Step 2: Mix
Fill containers 1/3 to 1/2 with Desitin (the Gotubb holds 1 tablespoon)
Add 15 drops of Tea Tree Oil (you may want to try with less and adjust to your needs)
Stir until thoroughly mixed with a Q-tip with cotton removed.
Fill container and stir again.
Step 3: Use
I just touch the pad of my index finger into the mixture about 1/3 the thickness of my finger
This is enough for one arm pit for me.
Rub it in.
It may leave some white residue on the inside of your shirt.
