It's the right tool for severely neglected drivetrains, heavily contaminated chains, and deep-cleaning sessions where you need to strip old lube, built-up grime, and stubborn grease back to bare metal before re-lubing. The solvent blend cuts through heavy contamination quickly and effectively, restoring components to near-new condition.\u003c\/p\u003e\n\n\u003cp\u003eA key feature of Fenwick's Drivetrain Degreaser is that it \u003cstrong\u003eleaves a protective oil film\u003c\/strong\u003e on components after use, helping to prevent rust and corrosion on bare metal surfaces during the period between degreasing and re-lubing. It can be used \u003cstrong\u003ewith or without water\u003c\/strong\u003e — apply directly to the chain, cassette, and derailleur, allow to penetrate, agitate with a brush, and either rinse with water or wipe away. For chain baths, pour directly into the bath and run the chain through. Always re-lube the chain thoroughly after degreasing before riding — the degreaser strips all lubrication from the chain.

The Drivetrain Degreaser is a solvent-based heavy-duty product for deep cleaning severely contaminated drivetrains. Use the Foaming Chain Cleaner for routine maintenance; use the Degreaser when you need to strip everything back and start fresh.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDo I need to rinse it off?\u003c\/strong\u003e\u003cbr\u003eThe degreaser can be used with or without water rinsing. For best results on heavily contaminated drivetrains, apply, allow to penetrate for a few minutes, agitate with a brush, then rinse with water. If working without water (e.g. in a workshop without a hose), apply, agitate, and wipe away with a clean cloth. Always re-lube the chain before riding regardless of whether you rinse.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs it safe on all bike components?\u003c\/strong\u003e\u003cbr\u003eThe degreaser is designed for metal drivetrain components — chains, cassettes, chainrings, and derailleurs.
