How to remove pit stains from your shirts?

If you are needing a deodorant then I would use this product. It doesnt leave a stain, its unscented and works great. Just run the tip under the sink, then under the pit......... :P

I dont think it is an anti-perspirant, but it definitely works and I dont have any stains on my shirts. I too wear a 100% cotton t-shirt under my company work shirt. You can probably find this at Walgreens or CVS etc. It also last forever, maybe a year or so for one stick.
