Can't go wrong
by Anonymous

This is the de facto standard for chain degreasers. I've used others and they've worked fine as well, but for some reason, I always go back to buying this brand. It gets the job done for sure. I run the chain through the PT chain cleaning tool twice, cleaning the tool out in between runs, and the chain ends up so sparkly clean you could eat off of it.

Effective

Cant verify if its actually 100% biodegradable, but it does a decent job as the liquid in a Park Tool chain cleaning tool. In a pinch, you can get quite a bit clean just squirting into a rag as well.

Works great

This product works great with the Park Tool cleaning device. The bottle does not last super long but it gets the chain very clean. It's the main cleaner that I use.

Thorough cleaning

I use this cleaner to completely de-grease chains when using lubes that require total removal of existing lubes. The Park solution cuts through everything on your chain with minimal scrubbing, though I recommend a chain cleaner tool with resevoirs and brushes to control the mess.

I use Park Chain cleaner in my chain cleaning device and it does a great job. I also use it to clean my pedals . I use an old toothbrush to clean the nonchain areas of my bike as well. Works great .

I use this with the PArk chain cleaning device, and get good results. I clean every 250 miles, and get 6000 miles out of a cassettechain combo, easy.

My Favorite Chain Degreaser

I use a couple of different products to clean my bike including the Park Tool ChainBrite Cleaner and the Spin Doctor Degreaser from Performance Bikes. I find that the Park Tool product does a much better job on my chain but costs more. I therefore use the ChainBrite on my chain and the Spin Doctor everywhere else.
