Degreaser 13 is a highly concentrated degreaser engineered for use with water to tackle tough degreasing tasks. Developed from scratch, specifically for the challenges of bicycle drivetrain degreasing, the advanced formula is engineered to fight its way to metal surfaces and stay there, then attack and break free the bonds holding oils, soils, and grime in place, and work together with water to dissolve and contain to carry it all away. Activate with water for incredible results on tough jobs or dilute for lighter degreasing tasks. Fully water soluble and further activated by scrubbing, agitation, and rinsing, the result is a spotless residue-free drivetrain. The advanced formula is also safe to use on any material, fully biodegradable, solvent-free, plant-derived, and zero-VOC.
