Simple Green on the engine, wheels and undercarriage. A good car wash soap on everything else. Nothing fancy here. The two coats of Zaino allow everything to wash off with ease. Speaking of I need to give mine a wash. Got caught in the rain in the mountains over the weekend and everything below the seat and tank is brown.

 

Have always used car wash soap in the past but got talked into trying S100 at the dealership.
Ok for a light wash but hard to beat hand washing to get all the places dirt really hides.

Then I noticed the guy in the back of the shop washing bikes the other day. Asked him what they used and he said, Bike Brite.My bike looks good when I get it back so I got some from JP cycles but haven't tried yet. Need to use up the S100 first.
