Hi Greg and Cathy I can understand the cleaning issue, if it wasn't for that bit of rain we would have been fine. After trying everything else on the chassis, I tried Shower Power on our ATV for two, it worked. I went through about 8 bottles, leave on as long as possible, soaking the mud, then Gernie off. What doesn't come off is imbedded in the galvanising and will need a wire brush to remove. Ours come up almost as new. Happy cleaning. Pete
