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.

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! 🚴🏍️💨

Use it for my bike - I ride 3-4,000 miles a year, so my bike can get pretty gross - this works well to clean things up with my tools

This product is 100/100, it leaves your chain looking brand new, I mean I was amazed!!

Update... Switch to waxing your chain and you'll never have to deal with cleaners like this again(try it, game changer)! First of all when you're done everything looks almost new. However, this is a harsh chemical and you need to be cautious of how much and where you put the spray on. Don't spray too much and a little quick brushing will get more clean with less chemical. Rinse very well and I think you will be as impressed as I was. My drive train came out about as clean as if I took the chain off. Wear gloves too, drys your skin. I took one star off because everyone who complained about the bottle is right. It leaks and is junk.

The best chain cleaner I've ever used.

This is a great addition to the regular Muc-Off cleaner I use to clean my MTB frame/wheels. It’s easy to apply and does a great job of getting mud and other debris off the cassette, chain and crank. I apply it, agitate with a brush and hose off for a squeaky clean result. I’ve recommended to my biking friends and those who’ve tried it agree with me. I use it after most dirt rides and it only requires 3-4 squirts so hopefully it will last well and prove good value for money.

this stuff is the best for quickly cleaning a drivetrain in an environmentally Safeway I’ve gotten away from using so much brake cleaner with this stuff available. My shifting is so much better.
