Awesome stuff, works like a charm, reusable
This stuff is awesome, all the grime will melt right off your drivetrain. Also, you can reuse it, so it ends up being pretty cheap per use. My advice is to transfer it to a good sized glass jar (if you put it in a plastic food container it will destroy the plastic). Then use it by taking your chain off putting your chain in the jar and shaking the jar for 30 seconds to a minute. Remove the chain, run it through a rag to get excess solvent off and then rinse it. For cassette and chainrings grab an old toothbrush and just dip the toothbrush into your jar of solvent and run that over your cassette and chainrings. It sounds tedious to be sitting there scrubbing with a toothbrush, but this solvent works so well that your components will be clean in seconds. Then just rinse everything off. Even when the liquid looks jet black it will continue to work well. I got about 10 cleanings out of one bottle. I find that it's a good idea to clean my drivetrain every 200-300 miles (or every other time I put more lube on it).
