No aerosol, no chemicals, no weird hand winding machines to attach. It is a simple spray and wipe chain cleaner. Yes it takes a little more elbow and effort, but it does work. I have been trying it so far over the winter to keep the drivetrain free of sand and grit, and so far it is pretty impressive. Orontas recommends giving your chain a simple wipe every 10 Scandinavian miles (100km/60miles) to keep it running smooth, and the bottle here gives you around 1000 cleans, so it is pretty good value as well. This coupled with their Type A or Type B lube should keep things running. It just feels nice to use something that is non-toxic, biodegradable and petroleum free. Treat the bike with a little natural love.
