just want to drop a line and let everyone know that i have used simple green cleaner on my bike for years with no problems...chrome, motor, tires, ect... just spray on and hose off really does a better job than sp 100 (my opinion) and cost a lot less just need to read the bottle for directions. (keep it in the wind)

 

Try the simple green extreme/powersports.It's actually blue and made for bikes....

 

My wife suggested to me that I try Mean Green cleaner on our bike. I was scared to death the first time I used it. Afraid of discoloring or any other bad result. It works great!!! Spray it on and wash off. Be sure the bike is cool and don't let it set very long. Fairly cheap too. Can be found at Dollar stores.
