Review on Arltb Bike Chain Scrubber Chain Brush Chain Gear Cleaner Bicycle Maintenance Care Tool Set for Cycling Road Bikes Mountain Bikes MTB by Aaron Ali

Works great! Makes cleaning my chain and cassette quick and easy. I spray some degreaser on the chain and cassette, then add some degreaser and water to the chain cleaner, run the chain through a bit, then use the brush on the teeth. The gear holder comes in handy when using the brush. I then run a soapy water circuit and the circuit is pretty clean. No more black dirt on anything the chain touches. Fair warning, if your chain is already dirty and dirty, it may take more effort to get it clean the first time.
