Muc-OffBio Drivetrain Cleaner | Effective Biodegradable Bicycle Chain Cleaner and Degreaser Spray | Suitable for All Types of Bike

Noticeably more effective than the WD40 bike degreaser I was using for my drivetrain. And maybe that was just a rookie mistake on my part. But wow this stuff gets the job done. Hundreds of miles of baked on gunk that the WD40 just didn’t quite remove - this stuff cut through the vast majority of it. If only I had been using it from the beginning!

This stuff works fast! Muc-Off Drivetrain Cleaner blasted through the built-up grime on my chain and cassette in seconds. Left everything looking brand new without any scrubbing. Smells good too—not harsh or chemical-y. Definitely a must-have for easy bike maintenance. The sprayer works well, and it's super simple to use!

I’ve tried several chain cleaners over the years, and Muc-Off Drive Chain Cleaner is by far one of the best! It effortlessly removes dirt, grime, and old lubricant, leaving my motorcycle/bicycle chain spotless and ready for fresh lubrication.Pros:✅ Powerful Cleaning Formula – Cuts through grease and grime quickly without excessive scrubbing.✅ Easy to Use – Just spray it on, let it sit for a few minutes, and wipe or rinse off—super effective!✅ Fast Drying – Dries quickly without leaving any residue, making re-lubrication easy.✅ Safe on O-Ring Chains – Doesn’t damage seals or affect performance.✅ Great Value for Money – A little goes a long way, so the bottle lasts a good while.Cons:🔸 Strong Smell – Like most powerful cleaners, the scent is quite strong, so using it in a well-ventilated area is best.🔸 Can Run Out Fast – If you clean your chain frequently, you might go through the bottle quicker than expected.Overall, this is a must-have for bikers and cyclists who want a clean, smooth-running chain with minimal effort. It works fast, does the job brilliantly, and keeps my drivetrain in top shape. Highly recommended! 🚴🏍️💨

Careful where you spray, it removes orange slime.

Muc Off Bio Drivetrain Cleaner is completely effective for cleaning your chain, cassette and chain ring. However, be aware that this product may harm the paint and/or any anodized surfaces on your bike.I read another reviewer's comments stating that the paint on his bike frame had been left with a dull finish. So, I decided to use Dawn dishwashing solution first. The Dawn removed some of the greasy buildup, but was not up to the task. So, I decided to carefully use this product. I used water to wet down my bike before carefully spraying the drivetrain cleaner.I was very surprised by the results. Using a soft bristle brush and a little agitation, my chain and cassette looked like new. This stuff works! I then thoroughly rinsed the components and washed the frame with Muc Off bike cleaner (the pink stuff).Last, I used my air compressor to blow off all excess water then wiped down my bike with a microfiber cloth.It wasn't until I got the the rear wheel that I discovered that the chain side of my rear alloy wheel (black, Bontrager Paradigm Comp 25) had small spots where it seems the black anodized finish had been damaged by the cleaner. The other side of the wheel has none of these spots. Thankfully, the painted finish of my frame is fine. I tried removing the spots using isopropyl alcohol, car polish and Dawn but none of these products removed the spots. It's almost as if the spots have been etched by the cleaner.My advice is use with extreme care. Cover anything that you do not want to possibly get damaged. Consider removing the chain and cleaning it off the bike. Also remove the rear wheel, and clean the cassette carefully. I will continue to use this product until if find a less caustic cleaner that is as effective.

This stuff is the best. We use it on all our Trek bikes.

This bicycle drivetrain cleaner works absolutely great. With just a few sprays, and a bit of a soak, all the grime came right off of my cassette, derailleur, chain, etc. The spray doesn’t smell bad either - it doesn’t smell harsh at all. It cut through the grime quite well and helped me get my bike’s drivetrain back to its brand-new shine. Great product.

Cleans bike chains very well, no strong odor.
