I have a confession...I sweat like a MAN! Not just when I'm running/working out, but also at work. I'm paranoid about smells & my clothes smelling. I hate when I go to iron a shirt around the underarm area, and no matter how many times I wash it, I can smell it when the heat hits it. Maybe I'm the only that is funky...I don't know. After trying many different products, I finally found something that works...Resolve Max. I spray it all around the underarm area right before I wash it. The item can even sit in the hamper for a day or so and the smell still comes out. I have been quite pleased with this product.
