Hey
what an interesting post. Rust, hm?
I'm not an expert so I don't have abillity to give an answer but question
Man have you had it store clean or is it a 'one time bbq and wait and do nothing with it but that until next time'-hookah. If it is that I can't answer I'm not expert.
Sorry don't feel offend I laugh right now and with laughing I'm not the one who cares a lot xD
Uhm.. but you clean it, right? With the brushes and some cleaner?
Greets from me
