How to clean a bong with percs?

I actually use hot water and oxy clean, works amazingly. I just fill up the part where the perc is with hot water, pour in some oxy, and let it soak for about a half hour. Looks like I just picked it up from the store after.

 

I heard kosher salt is the best stuff to use because it is less prone to leaving small scratches? I know on my old bong I used to use ISO and salt and it would leave these really tiny scratches in the glass that would turn brown and resiny on like the first bowl from them filling up with the excess resin.

Now I just use formula 420, I know its the same is kosher salt and ISO but its just easier for me and I get it really cheap at the smoke shop in my town. Oh and I got a triple perc Hi Si with honeycomb diffuser and inline ash catcher. Just FYI, you wanna keep up with cleaning a percd bong or even just a multi chambered bubbler because if you wait too long sometimes you get a big chunk of resin in one of the percs that will crust onto the glass and will refuse to come out.

 

Of course not, after I'm done I clean out the oxy quite well.

 

If you were to place your A/C into boiling water, the bubbles would knock it around alot inside the pot so it risks being cracked.

 

High risk of cracking in boiling water.
Hot tap water should be sufficient - on top of that the force coming from the Tap will remove some stuck on Resin if hot.

MY DD Cleaning Process: (this goes down every 12-24hrs)
1.) Drain old water
2.) Fill/Rinse/Shake some hot tap water around inside, drain.
3.) Little Kosher Salt goes in the bong and slide (you don't need a lot)
4.) Add a little ISO 99-91% (you don't need a lot)
5.) Shake Well. The salt breaks off any stuck resin - ISO cleans. (in reality salt is only needed every 3x)
6.) Dump/Drain/Rinse(hot then cold tap-water)/Dry
7.) Fill with cold water from the fridge

Everyone that uses my sovereignty thinks it is the first time its used, every time.
