I use Simple Green to clean my chain and bike. I use a wallpaper tray to catch the sludge that comes off of the chain and a top cover of the bucket to shield my rear disc from that same sludge while washing my bike. I simply cut out a pie shape in the bucket lid so I can slide it over the axle. And I have used a Grunge Brush for years on my motorcycles, but have found and used a better product. The Tirox 360 degree Brush for Chain. At first it’s a little tricky to spin onto the chain, but man once done it’s a breeze to use and cleans ALL SIDES of the chain. That’s it for now!
