I'll tell you one thing, that ultrasonic cleaner can pull some darn stuff off the chain.
Each year our family goes to Hilton Head island, I ride up and down the beach every day.
When I get home, I disassemble the bike, and the SAND that fills the base of the ultrasonic cleaner from the chain alone is huge.
Also- I'm a wattage freak, but I'm not going to dissect wattage over a chain- what I will say, is that with a sharp clean drivetrain, you will FEEL SEXY and psychologically feel faster because of it. It is a mental bonus. It is like a clean car or garage. It will lift your spirits
