First, Im kinda picky about keeping my gear nice. Second, since I have to practice in the garage. my board gets dirty from my feet, even tho I sweep the floor constantly. So, Ive got sand on the board tween the pedals and on the pedals in the tread and where the controls are.. I keep it covered when not in use. Anyhow, any tips on cleaning it?? I wipe with rags, wisk broom and canned air. Anyone have any other ideas how to clean em?? Thank you!
