Used to clean the cassette, chain, chainrings. Works as advertised. Super fast and effective.
Does the best job I have found for cleaning disc brakes and rotors, only time will tell. It is kinda pricy but we will see if I purchase a second bottle.
The reviews on Silca's website are true, this stuff works like magic. I do few quick sprays on cassette, rotors, and calipers and let it sit for several minutes. Light brushing on the cassette and then rinse everything with water. Water coming out of the calipers was black. Brakes no longer squeal and cassette is sparkling. Saves way more effort and time over any other cleaning protocol.
The easiest, most effective drive train and brake cleaner I have used. Truly amazing how clean it gets the drive train and how easily, leaving the wax lube untouched. I can clean without worrying about over spray. The best maintenance product I have found for my bike.
