Muc-Off Bio Degreaser, 500 Milliliters - Water-Soluble, Biodegradable Bike Degreaser Spray - Effectively Deep Cleans Greasy Bicycle Parts

I've used it twice to clean the chain and cassette of my bike. Both times it has worked very well. I just spray it onto the components, let it sit for a few minutes, and then rinse it with water. Very easy to use.

I am typically a simple-green and toothbrush kind of person, but for my fixed gear this is my go to. I put some cardboard down in my apartment, put the bike on the work stand, spray onto a rag, and wipe the chain, sprockets, and chainring clean. This spray smells FANTASTIC. It makes me so upset that it's inedible, but also I get whiffs of it as I'm on rides after the clean. Not a big aerosol person, either, but this is a product I will return to.

This stuff is great!! And smells frikn awesome!! I have used this on my Niner RKT RDO as well as my Specialized S-Works. I spray on the metal component or rag and then wipe. Won’t disappoint!

The stuff works great!, simply spray on and watch the dirt and grime literally drip off. You will have to get somewhat personal if working outside (which is recommend to avoid some light headedness) and get really close, especially along the chain, but it works great once on the components and drivetrain. It does have a strange candy like aroma, although.

Used it on bike chain and headset. Also used in various garage door components that were "excessively lubricated". Worked very well. Does not smell bad and also does not leave a greasy residue.

This stuff is amazing!! It does a great job of removing dirt and grease, and it smells great !!

Good value

This can came without a spray nozzle and it has a custom diameter spout. So it’s brand new and I can use it. The product is fantastic but I useable until I get another one to scavenge the top sprayer.
