Muc-OffBio Drivetrain Cleaner, 500 Milliliters - Effective Biodegradable Bicycle Chain Cleaner and Degreaser Spray - Suitable for All Types of Bike

Careful where you spray, it removes orange slime.

Cleans bike chains very well, no strong odor.

I’ve been using this to clean off my chain for about a year now and I don’t think I’ll ever go back.Handy tip: take the chain off and put it into a jar. Pour some degreaser into the jar, close the lid, and shake it for a few minutes. Best chain clean I’ve ever gotten (not better than an ultrasonic bath, but better than a chain cleaning tool). When you’re done, let the degreaser settle in the jar for a day, and the grit and grime settles to the bottom. If you’re careful, you can reuse about 80% of the liquid. It makes a bottle go a lot further this way too.

In the world of cycling where cost to benefit ratio is often preposterous, this is a product that is truly worth the money. I have used about 10 different degreasers. If you want to use minimal water on your bike (I spray this off the drivetrain from a camelbak bottle and not a hose), this degreaser is the absolute best in the game. You can literally watch it melt the grime away from your drivetrain. I even like to spray it on and wipe it off because I do my best not to wash my bike so I can keep the bearings running smooth as long as possible. This is also biodegrade-able so it’s much less harsh on the plastic jockey wheels in your derailleur and it doesn’t leave stains on the ground if you’re cleaning your bike over concrete.Muc Off is just amazing with the alchemy they use to keep your bike running clean and on-point with the shifting. I have used their dry lube for years. You will not regret buying this. The money you invest on this degreaser will save you money in the drivetrain parts you are preserving.

I had pretty good using this degreaser, especially when cleaning off old chains that have lots of muck. But degreasing new chains took a lot more work.It's nice that it's biodegradable and it can be disposed of just by diluting it. But, the silca degreaser just works better.

Works better than the "competitor" by far... Frankly, it was amazing how quickly it worked.. strongly recommend.

I plan on trying out different drivetrain cleaners.This one works really well (especially after having the muc-off lube gunk up my cassette)If the cassette is really gunked up it might take a little longer so let it sit, scrub, spray but works wellThe product definitely gets on my disc brake & rotors but hasn't made them squeak or squeal (I usually clean them with isopropyl alcohol after but not always)Ps. I recently switched to progold chain lube and have no had my cassette get all gunked up and is much easier to clean when needed.

Woooow this thing Rocks. It cleans so effortlyHighly recommend
