NO DO NOT DO THAT!! The oils in Armor-all with eat away the latex from what I\'ve heard. There may be a special kind to use that I don\'t know of, but I sure as hell wouldn\'t suggest spraying down your collection.
you have been mis-informed, you do not use armorall to protect a mask. THis would lead someone to believe you can use armor all protectant on a mask. I have, however heard that you can use armorall to clean a mask, armor all **cleaner** NOT protectant. I think it is called vinyl cleaner or something like that. I do not know if this is safe for masks thought, and I would not try it myself when you can clean a mask with water and if needed some mild soap. so why risk it?
