Degreaser 13 takes degreasing chemistry to new levels with performance that must be seen to be believed. Your drivetrain hasn't been this clean since the day you bought it! 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 finally dissolve and contain to carry it all away. Fully water soluble and further activated by light scrubbing and rinsing, the result is a spotless residue-free drivetrain with every surface cleaned completely. Pedro's advanced formula is also safe to use on any material, fully biodegradable, solvent-free, plant-derived, and zero-VOC.
