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! 🚴🏍️💨

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.

Not the greatest product but it cleans.

Easy to use and cleans grease right off the chain without even scrubbing.

I had ridden my new bike through less than ideal conditions (through water, freshly cut grass clippings and dust) and got a lot of gunk built up into the drive train. One application of Muc Off Bio Drivetrain Cleaner, and all the build up melted away. Sparkly silver chain and cassette appeared as the black gunk washed off. I was skeptical if it would be worth it, but after failed attempts with household options, Muc Off delivered. The bottle is enough for years to come. A great investment to keep up with routine drivetain maintenance.

Man this stuff is amazing. Knocks all that stubborness right off the drove train. It gets working immediately I ain’t had a drive train clean so easily, definitely recommend! Also with this get the bike protect and make sure you oil your chain after rinse the potent hulk pee off!
