I have switched to aluminum free deodorant, but was experiencing underarm odor using these deodorants. I am now using a combination of an aluminum-free deodorant along with a solution I created to fortify the effectiveness of the deodorant. My formula is 7 tsp of water, 1 tsp of baking soda, 1 ml of tea tree oil, and 1 tsp of witch hazel. Shake vigorously to dissolve the soda. Pour into a small atomizing bottle and spray on after appying deodorant. I usually spray three sprays. It is now working fine and I am now odor free.
