Anyway, I use a Stockton Minister Chain Brush to clean the chain and this particular brush has the full approval of my dealer's service department. This is a simple tool and the U-Shaped end works well. Not sure what the brush on the other end is for, but I also use a wire brush on the sprocket when I notice the build up. The tool cost $8.00 at Cycle Gear and makes cleaning pretty easy. I do not use any cleaning chemicals on the chain.
Lay the towels down to soak up any lube that drips. No need to make a mess, now.
