Black Jade

I heard the best way to clean the undersuit (black piece) is to use a spray bottle containing alcohol and water, spray down the suit and then use febreeze for a quick and easy clean. Would the vets here recommend this method after the heated troops? Also, my cumberbund is showing staining from sweat, what is the best method to attack these stains? Taking all and any advice, thank you in advance. 😃
