I'm bad as far as it goes for cleaning my caRs. Maybe once a month I might give them a good spray with an air compressor, or if they happen to have gotten a lot of mud on them from the wet track I might use a toothbrush to get off excess junk. But most of the time I barely clean them throughout the outdoor season. Are usually clean them up when They get broken down and checked over for the next season. LOL. Unless you have a ton of mud and dirt buildup on it it's probably minimal difference as far as the run, other than maybe in the joints where they pivot for the arms and the shark they get broken down and checked over for the next season.
