Cleaning a glass bubbler

What are you guys using to clean out the sticky funky junkiness? (+rep)

I just use 91% or 99% ISO with a little bit of salt to act as my scrubbing agent lol.

I use the ROOR cleaning solution.. it takes only about 5 minutes to use and it gets your piece really really clean without having to use a pipe cleaner or anything like that.
I also have a buddy who uses hot water and baking soda, he swears by it but i don't really know too much about this or how well it truly works.
