With isopropyl alcohol in short supply, I wanted to test out some alternative methods for cleaning pipes. I tested these three popular methods; vinegar and baking soda, simply boiling water and nail polish remover.
Vinegar and Baking Soda - my most preferred method!
Submerge the pipe in vinegar, add a dash of baking soda. It will bubble up and get really fizzy! Let sit in that solution for 3 hours. Remove, and rinse well. Clean the interior chamber with pipe cleaners if you have them.
This non-toxic cleaning solution works really well and you usually have the ingredients on hand anyway.
Boiling Water - works alright but very smelly.
Place the pipe in a small pot, cover with water and boil. Always use a pot with a lid, this method smells terrible. I left it in for about 30 minutes. Removed carefully, its very hot! Rinse well and use a pipe cleaner if you can.
Boiling water does remove a decent amount of resin, but not all of it. Definitely not the most efficient way to clean.
Nail Polish Remover - super toxic, don't do it.
Place the pipe in a small glass container, fill with enough nail polish remover to submerge the pipe. Let sit for 3 hours.
This method completely obliterates resin. HOWEVER, it is extremely toxic and damaging to your lungs to inhale.
I don't recommend ever using nail polish on any smokeware, ever.
