A skateboard is small enough to be an afterthought, but its wheels carry grit that transfers to whatever it touches next. A quick wipe and a towel wrap solve that in under ten minutes.
Pro tip: Stack multiple skateboards wheels-to-wheels rather than deck-to-deck, since grip tape scratches grip tape less than it scratches a smooth graphic deck.
Watch out: Grip tape is abrasive enough to scratch soft plastic toys or painted furniture surfaces it is pressed against; keep it wrapped or faced away from anything delicate.
