Grunge Be Gone
Nice kit with everything you need to get started with periodic chain cleaning. Was pleasantly surprised at its ease of use and how well it took the grunge off my chain (where did all this come from???). Made one pass with the provided Park Tool solution and a second pass with dish-washing soap and water (recommended in the instructions) - both worked well.

A huge improvement over my ancient Park chain cleaner
I finally used this for the first time, and love it. It assembles easily, operates smoothly, easy to fill without making a mess, and really gets the gunk off your chain. The wire brush is a welcome plus to get at the rear sprockets too. I had been using Park's previous iteration of this device, some 30+ years old. It finally gave up the ghost, and I think the new design is a big improvement. If you're still using a toothbrush and some rags, treat yourself and get this - you'll be glad you did. It makes chain cleaning quick and (mostly) mess free.

Effective cleaning tool
I wanted to improve my chain life and decided to be more attentive to cleaning and oiling my chain between rides. This process is made so much easier using this chain cleaning tool and cleaning product from Park Tools and does a really good job removing old muck and oil. Highly recommended

Worked well, need larger bottle of solution
My chain had not been cleaned well for over 1,000 miles. This contraption did the job with minimal effort. The brushes cpuld be better made, as several bristles came out during the cleaning. The instructions recommend repeating the application, changing the cleaning solution in between. The bottle only has enough fluid for 3 runs, so if you will need to buy more to make a second full cleaning. Be sure to wear goggles or a safety shield during the cleaning operation. It stings when the fluid gets in your eye, as I found out the hard way.

Good system
The clips on the cleaner break but if you are careful they are capable of holding out
The unit cleans very well
And the Pedro cleaner is very efficient
All in a good purchase if you are careful with the clips when attaching and opening them

This makes cleaning my chain a breeze!
I really like the chain gang cleaning kit. It is easy to use and works really quickly to get my bike chain looking good as new. The few drawbacks that I have are that it is hard to tell which side should be facing the front of the bike and filling the handle up with degreaser is challenging. I lost a lot of degreaser on the ground the first time I tried to use this. But, I think with a little practice I'll be doing just fine.

Great kit for keeping your chain clean
My old chain cleaning tool broke so I had to pitch it (don't recall the manufacturer of it) but this one by Park Tool is made much better and is easy to use. I wish it contained a larger container of chain degreasing fluid (I had three bike chains to clean) but you can't have everything.

Awesome alternative if you don't want to use sponge or rags
Got this product because I was destroying shop rags and sponges everytime I washed my biks. In addition, This is a great way to keep your hands clean if you just want a quick clean of the chain if they bike isn't so dirty.

So Easy and Painless to Use
Really all you need to clean your chain before applying your favorite chain lube. What a difference it makes to the shifting response with a clean and freshly lubed chain. I ride 100+ miles a week and the grime packs on the chain quickly. This kit makes it easy to thoroughly clean your chain and gears. A must for any serious cyclist.

Most chains are not cleaned enough.
It works good, with no problems. It�s not the metal one, but treat it well and it will last. Wipe off the chain with a rag first to get the heavy stuff off.

Keeps regular chain cleaning clean
Remember toothbrushing chains in the past. The Park Chain Gang kit does it even better with less mess. I like that they provide the brush which fits just right between the cogs for any large bits...well thought out design and application.

Chain Cleaner easy to use
This is an easy way to clean your chain, Just clip chain in case with cleaner and pedal. Takes all the dirt and grime off then just rinse off with water wipe clean with rag. Let dry ready for chain lube. I then just rinse out case with hose.

Works great
I use it at least once per month on both my bikes to remove all the dirt and grime. Its very simple to use and works well with any degreaser, including Simple Green, or with Dawn detergent.

Works ok - but not worth the cost
I have lots of Park products. This product is similar to products at Bog Box stores. I like its performance. However, after only using it a few times the handle totally broke off and cannot be used. The cleansing unit works fine but i have to now hold it manually. as to the cleaning fluid It is ok. Frankly. I also use Dawn dishwashing liquid and it cuts the dirt and grease for a fraction of the cost.

Hey, this thing works!
I had been a little skeptical that the device would provide a thorough cleaning but the first use blew away my doubts. The chain was squeaky clean. Only drawback was that a dozen or so bristles from the internal brushes broke off and lodged in the chain. Easily removed but Im a bit concerned about durability. The cleaning solvent worked fine with no offensive odor. The small brush was handy for cleaning the freewheel and derailleur elements.
