Best way to clear dust/bugs out of bongs in a store WITHOUT ISO
So I work in a smoke shop in my area, recently got a couple of raises and more supervisor type responsibilities. Problem is the store I work at isn't very busy so I spend a lot of my time just cleaning the store.
Last time I rinsed the bugs and dust out of the bongs with just tap water and it worked well enough, except a few with perks and recyclers didn't want to fully drain and those drops that stayed caused condensation and left residue after evaporating.
Obviously I know at home iso and salt is good for cleaning a dirty bong, but I know they aren't gonna provide me iso just to clean dust out, so I'm looking for any recommendations to not have this issue in the future hopefully.
