Re: Senior Shisha Question regarding this 'Stuff'
my mya has a little bit of that on some of the inside parts. i think it is water stains/corrosion from water being left on it. get a small brush that is meant to go in there and brush it out, and dry it out. if it doesnt go away with that i wouldnt worry about it unless it starts to get a whole lot worse and cause pitting/taste/etc
