(prolly depends on the design but)
for me completely clear & clean everytime, i love it

Exactly this! I have been doing it for a while. I never wanted to research what reactions are caused adding salt to isopro though, I just hold my breath and shake. Sparkly clean every time. I tried doing it with water, but it just dissolved the salt, so I am assuming there is little to no reaction with alcohol as the salt doesn't dissolve.

the salt is used for being abrasive, basically "scrapes" any build up off your glass but without scratching the glass
due to this coarse salt is the best :3

agreed about adding a little salt to your iso - MUCH more effective

Ahh, gotta have pristine glassware!
Run it under a really hot tap so most of the worst melts off, then a few squirts of iso in a spray bottle and rinse. Takes 30 seconds

I find a quick swizzle around with a cocktail stick is great for grabbing all the tar out of bowl stems too.
