BBB BioDrivetrain Cleaner, plant-based

BBB’s cleaner is the environmentally specified option, and it publishes more on that front than anything else here.

What the manufacturer publishes

A plant-based bicycle chain cleaner, 100% biodegradable. Effortless removal of dirt and the most stubborn grease from the chain. No harmful chemicals left behind in nature. One hundred per cent recycled PET packaging, and 100% free of microplastics.

Why this matters for this specific product

A drivetrain clean produces run-off. On a driveway it goes into a drain; in a garden it goes into the soil. Unlike most bike products, a degreaser is designed to be washed away, so what it is made of has somewhere to go.

The practical trade

Solvent aerosols work fast because they are aggressive. A plant-based liquid generally needs to sit on the chain longer and be worked with a brush. That is a few extra minutes rather than a failure to clean, and it is worth knowing before you expect aerosol behavior.

The liquid advantage

No overspray. An aerosol reaches further than the nozzle suggests, and disc rotors are close. A liquid applied with a brush goes only where you put it, which removes the single biggest hazard of drivetrain cleaning.
