Foaming Drivetrain Bike Degreaser - Mountain & Road, 500 ml | High-Strength Drivetrain Cleaner & Chain Degreaser Spray, Biodegradable, Safe on Waterproof Grease & E-Bikes, Bicycle

Works great as a regular chain cleaner. Gets off grease and oil fairly well. Easy to use, pleasant smell. Not for really heavily greased chains but you shouldn't have one of the if you are looking after it properly anyway!

It works really well. If you get a brush head for your drill, drop your cassette in a bucket. Spray this all over it. And 5 mins later whiz it up like it’s a smoothie - voila, gleaming cassette.

A quick squirt then agitate the chain and it did its job. Be careful not to spray too much over an unsuitable surface as it is going to drip, potentially oily grime. But it was the best value cleaner I found and got the chain very clean ready for the next ride.

It cleaned my bike up excellently…..👍

Cleaned my cassette and chain, dirt just fell off with a bit off agitating

Easy to use and very effective- made a great job degreasing the chain and gears in my EMTB

Does exactly what it says. Had mud, grease, grime that had been dried on for about 4 years where I had not rode for a while. Didn’t think to get a photo of it before hand, but cleaned up very well!

This stuff is so good! I usually use MO chain cleaner as it's the most effective, but it's expensive and I find it doesn't go far. I've tried other brands that pretty much do nothing so when I needed some more I was going to get MO again but saw Peaty's brand one and thought; why not? Well, this stuff is amazing to say the least. It costs less, you need less of it and it does such a good job. Spray it on, it foams so it kinda stays put. Leave it a few minutes and then with minimal scrubbing you rinse it off and honestly, the chain looks new. Strangely enough as well I find the chain seems to stay cleaner for longer after being washed, maybe because it's a deep clean, I don't know, but it does. I can't recommend this enough and it should last a long time. Good lad, Peaty! Update; December '25; Unfortunately the initial honeymoon period has worn off with this product, it seems fine to use during the warmer months and works well but does not perform well on winter chain cleans. Even scrubbing after applying is still leaving a dirty chain and cassette, plus the spray bottle has stopped spraying properly and spits more than it does spray. Shame, initially I loved it. I've had to dock 2 stars and will have to go back to MO. Sorry, Peaty :(

C'est le dégraissant que je préfères, je recommande. Et la livraison rapide et conforme est un plus.

This seems to do a pretty quick job degreasing the cassette. Better than anything else I've tried.

Immer wieder. Macht was er soll

Es un buen producto de limpieza

JUST WOW! I’m still in the middle of using this product and had to stop to write a review. I bought my son a 2008 Trek Alpha secondhand — this thing had been through the wringer, with original parts gunked up and rusty as you can imagine. I even went as far as buying new drivetrain parts, including a cassette. But upon cleaning the original cassette from 2008 to replace it, I was blown away. It literally looks brand new! I’m happy to say this product has already saved me $80, since I’ll be returning the cassette I just ordered 😆. THANK YOU, PEATY! I forgot to take a before picture, but it was bad enough for me to buy a new one. Sometimes all it takes is a good wash with a really great product.
