Muc-Off Bio Degreaser 500ml

The spray nozzle makes it easy to hit every nook in the drivetrain, and the grime just melts off without harsh scrubbing. I used it on both the chain and the frame, and it rinsed clean with no residue. Glad it's biodegradable, too, since I usually wash on the lawn.

That citrus-ish smell is actually pleasant while it strips off the chain grease effortlessly, and I’m glad it’s safe on the plastic bits too. Thoughtful that it’s biodegradable, so I don’t feel guilty hosing it down the drain.

It worked well on my bike chain grease, but I had to use quite a lot more than I expected to get the really caked-on grime off. The bio claim is a nice touch, though.
