So I had work done to my 2120. I have two little ones and had railings put in so there's protection from the engine well. Well, I guess the guys that did it didn't rinse out the shavings, and it rained. The shavings got wet, and rusted. Now, I can't get rid of the many little rust spots. They seem to have adhered to the floor! I tried borax and lemon, coca cola, starbrite deck cleaner, and soap and water. Help!
