Clean out underneath the ramp 2 times a year or more frequently if you have a lot of gutter build-up. To turn the ramp over, start at one end, pull the top of the ramp up and out toward the street. Keep flipping the top out as you walk along the ramp. Use a hose to clean the ramp's underside and the gutter. To return in place, simply start at one end and flip back toward curb as you walk along the ramp.
