My bowl went from clear to pitch black. I refuse to clean it because the blue and white swirls look way cooler with the black outline.
I rinse and change water immediately after smoking and then clean everything in a dish tub full of hot water and a couple scoops of oxiclean weekly. My pieces never look dirty. That's the way I like it
Used to let my bongs and bowls get caked in res, then I realized it tastes like shit. Now I use iSO and salt 2 times a week, and new water every sesh.
before and in between every single toke of the sesh i clean the bong with iso/salt and boil water and put the popper shaft/bowl in boiling water and change the water and add fresh ice. it's good you can use the same boiling water for cleaning the bowl/shaft in between tokes before it cools down and you have to reboil some water. my piece doesn't haev 1 piece of resin in it. at any given moment you could switch it out for an identical piece at a bong shop and they wouldn't be able to tell the difference.
If I've got cold water in it, I'll leave it until it becomes room temp. Just plain Jane water, I kinda just eyeball it (usually 10-12 bowls) or I'll clean it after every finished smoke session if I can. My pipe, I just clean every end of smoke session. I use hydro-peroxide and super hot water (close but not boiling)
I change the water every couple hours. The downstem only gets cleaned when clogged and i go thru 3-4 bowls a week.
I let my pipe get as dirty as my bathtub. WARNING: Shocking and Disturbing Image Below -----------------------------------------------------------------
^ I think I'd feel cleaner not showering than showering in that I keep my pipes and bubbler clean. My percolator bong is hard as fuck to clean, I wash it out frequently and I've used the salt and alcohol but I just can't get it clear. My first spoon I let get so dirty, my friends who used it thought it was wood until I cleaned it.
