WD-40 Company 390241 Bike Chain Cleaner Degreaser 10 Oz

Product Description

The WD-40 COMPANY 390241 is a foaming bike chain cleaner and degreaser formulated to cling to drivetrain surfaces and break down stubborn grease and grime. The foaming action penetrates quickly, lifting contamination from chain links, cassettes, derailleurs, and other drivetrain components. The formula is safe for bike finishes and does not contain citrus compounds, which are known to degrade varnishes and painted surfaces. This product is packaged in a 10 oz aerosol and is suited for use by bicycle mechanics, fleet service techs, and experienced cyclists performing their own drivetrain maintenance.

The 390241 is designed for drivetrain cleaning applications across road, mountain, and commuter bicycles. It is applied directly to the chain, chainrings, cassette, and derailleur pulleys to dissolve grease buildup before rinsing. The product is well-suited for shop environments that service multiple bikes or for field use where fast-acting degreasing is needed. It ships in a package quantity of six units per case, making it practical for shops maintaining regular inventory.

Installation Notes

Apply to a dry or lightly soiled drivetrain before washing. Allow the foam to dwell briefly so it can penetrate grease deposits before rinsing with water. Use in a well-ventilated area and avoid contact with brake pads, rotors, and braking surfaces. After cleaning and rinsing, allow the drivetrain to dry fully before applying a fresh chain lubricant.
