Dont waste your money on store bought cleaners, rubbing alcohool and salt work fine. The only difference is the smell, and If you rinse it out enough, it doesnt even matter.

You need ALOT of salt, and less alcohol. You need the mixture to be a little more liquid than sludge.. Does that make sense? Basically you want to be able to shake it around okay in there, but still have it really thick with salt.
