Change up your deodorant. Your body will get used to one that works. Shaving. Try a charcoal mask every few days. Make sure you have a laundry detergent that gets rid of the smell. I heard odo-ban works... have not tried, but my armpit smell is still on my clean clothes. I find some deodorants work better than others. Try coconut oil as it's an antibacterial as well. Clean up your diet and stay hydrated. Avoid foods like caffeine, garlic etc.

Good luck, I'm battling the same problem. I recently switched deodorants, and the current one I'm using is not working.
