Strong and safe! a new technology degreaser that quickly cleans without damage to rubber or plastic components. Strong enough for the grimiest metal parts, yet safe enough to clean parts with rubber o-rings and seals, urethane elastomers and painted surfaces. Ecotech bike degreaser features 100% active (no water) biodegradable degreasing solvents, so bicycle chains and gears are cleaned more quickly, and often without a need for a water rinse. Less time cleaning means more time riding! powerful soy-extracted solvents break down grease, grime, and stubborn soils with amazing ease and will biodegrade rapidly when they get in the environment.
