Re: Dumb newbie questions
its good to use lemon juice since its natural and wont damage anything. I don't recommend using vinegar at all since it could harm the stem(corrode). I've never used soap mainly because I don't like the fact ill be breathing smoke from it and may have some left over in the stem. I would just save soap for the dishes.
As far as knocking it down. It falling wont hurt the actual hookah, but the coals go flying. so being on carpet you care about wouldn't be the most wise choice. getting a base protector would help balance the rig up a bit so it would be harder to knock over
