Really messy here, so don't go wild, but try to get 90% of the slop off it....Diluted SimpleGreen or Purple stuff and warm water with standard hose nozzle. I don't use powerwashers on my machines. Too much pressure. Warm water does wonders for loosening clay with the Green or Purple stuff. It's just so sloppy here in Maine....you wade through nasty clay and a mix of rotting water all the time. It's pointless to make it "shine". The first day I rode it I looked at it long and hard and took some pictures knowing it would NEVER look the same within minutes of leaving the driveway.What does everyone use to make her shine ?
