Bike degreaser is a cleaner that dissolves old chain oil and grime. It's for the drivetrain, not the whole bike, and it strips all the lube, so the chain needs fresh lube afterward.

What it's used for

Cleaning the chain, cogs, chainrings and pulleys. See clean and lube a chain. Park Tool says CB-4 works in a chain scrubber or with a brush on cassettes, chainrings and pulleys (Park Tool CB-4).
Cleaning the drivetrain during a wash. See wash an e-bike safely.

What to look for

A bike degreaser for the drivetrain, gentle soap for the frame. Bosch says frame washing should use bike shampoo or a soap that isn't aggressive or strongly degreasing (Bosch).
Safe on your bike's materials. Park Tool says CB-4 won't harm alloy, plastic, rubber or carbon fiber parts (Park Tool CB-4).
Rinses clean. REI's listing says Finish Line Citrus Degreaser rinses off with water (REI, Finish Line Citrus Degreaser). It is listed as flammable and ships by ground only (REI).

Keep degreaser away from brake pads and rotors, the display, the motor and the battery contacts. Take the battery out before you clean.
