Re: Best product to use polish your hookah?
The only hookah I would polish would be the solid brass Engineer I had. I wasn't goning green, just would loose some of it's luster after 6 months of sitting alone on the shelf (no, I didn't smoke from it often).
I used the jewlery polishing clothes my BF had for his watch. Worked like a dream and didn't really need to be washed off. If you use Brasso or other polishes (not car wax) make sure to rinse it well - you wouldn't want any of that stuff to somehow get inside the stem, hose or bowl. Could be nasty.
And if you use car wax, be careful of how high on the stem you go (or if you have a short stem) - it can heat up and may melt the wax/polish right off (my MYA QT gets quite warm while smoking).
Good luck and make sure to post the pictures.
