I use Laser Media head cleaning solution ( I think it's L100). From the smell, it has naptha in it. Most of the time, I just clean the rollers with distilled water and every once in a while, S-721H from American recording Tech..It smells like MEK. After cleaning with that, I use Rubber Renue by MG Chemicals. And that smells like spearmint. If you mix them all together, they taste kinda like Jagermeister (just kidding, do not put any of these in any opening of your body and yes, that includes your belly button!).
