I've had to take off or loosen my skidplate to wash off the mud, dirt, grass, sticks and sand that builds in there. It's unbelievable how much crap gets trapped in there and in the CV Boot Guards. I wash my Grizzly off everytime I Ride it in muddy or dusty conditons. I use my pressure washer to wash it off if I got a lot of mud on it but I'm careful not to put too much pressure on the engine and brake parts. I've got a lot of experience on using pressure washers. The only thing I really don't like about the Grizzly is that it eats up too much gas. I wish it had fuel injection. Everything else is just perfect.
