I found a easy way to keep my buggy clean now. I bought some spray silicon from the auto parts store while and I was doing some repairs I got everything as clean as I could get it and when I was finished. I just misted the whole chassis down, the stuff dries after a little while and leaves a silicon coating behind. Now nothing stays stuck, the air compressor gets most of the loose stuff off and the using the brush the dirt just comes of. When it looks like the coatings wearing off I just respray.
