Using Golden Degreaser is easy! All you need is a small brush to scrub your cassette, chain and rings. Put some Golden Degreaser on the parts, then on the brush and scrub. Within seconds, the old lube and dirt just dissolve. Rinse off with a fine spray of water to completely remove all traces of the degreaser and old deposits. In case there is no access to running water, you can completely wash a drivetrain with as little as a single quart of water in a sprayer bottle when using Golden Degreaser.
