A friend recommended this so I picked it up and it has not disappointed! I use diluted Simple Green and in less than 10 minutes, the chain looks like new. I clean the chain, empty/rise the machine, add new Simple Green, and clean the chain a second time. This machine has saved me so much time, I highly recommend it. If you pedal backwards too fast, you might spill some of the liquid. Just keep the pedaling smooth and even and you shouldn't have an issue with spills or drips.
I can't believe I've gone years without this handy tool. I used to clean chains by hand with a rag and lube and was never satisfied with the result. This scrubber really works. It's a bit pricey, but then again everything park sells is. It's seems to be better quality than the knock off brands.
This unit's design is what the other famous maker copied theirs after! I use to take my chains apart and clean them in my solvent basin, with this device I find it unnecessary to remove the chain any more saving me time and hassle, and it cleans as well as the basin did. I usually clean the chain once, drain, clean the machine, and refill and repeat, then since the second filling is hardly discolored from dirt I top off the reservoir and clean a chain on another bike, I know that sounds weird but it works if you have to clean 2 or more chains while using less cleaning fluid. The brushes and the foam sponge will wear out but most LBS's carry the replacement part kit which the other maker is much more difficult to find. Word of warning, obviously do not use this near a wall, carpet or some sort of flooring you don't want solvent and oil to get on; also back pedal the chain slowly through the device or it will splatter the solvent and oil all over the place including on your bike, so take your time and run it through about 20 complete cycles of the chain.
Check it out a chain scrubber that actually scrubs chains! I used this almost monthly to clean my chain and works flawlessly all the scrubs hold up great and its easy to clean!
I've use several chain cleaning tools, but the Park Tool Cyclone Chain Scrubber does the job best, does not fall apart and the tip on the instructions saves me a ton of money. Once I ran out of citrus cleaner, the tip says to use water diluted Dawn dish soap for chain cleaner fluid. It works great and cleans up easy.
This baby lives up to the hype. I wash my chain every other ride and it only takes 10 minutes with this. I like simple green diluted to 50/50 to scrub my chains
I have used this for a year. Used with proper degreaser it will completely clean your chain to a like new state. I use zep citrus degreaser from a hardware store. The only problem I have with this scrubber is the brush bristles get stuck in the chain. So make sure you pull them out.
