Brass Core Hookah Question for you metal heads
I have the KM Amer that is brass cored. Sometimes when I wash it and let it air dry I get some green crap that comes out of it. I am sure someone liek fursaken or one of you are gonna tell me of the metal properties etc etc but what I wanna know is, is it safe? what precautions should I use? Should I stop cleaning with lemon juice?
The greatest obstacle to discovery isn't ignorance, but the illusion of knowledge
