The whole patio is removable and adjustable. The ramp is attached to one grid which is laying on two wonder bars and clipped to the side with a carabiner. So for cleaning I lift out the coroplast, and then can lift out the ramp so it's super easy to clean. I might have to add some flaps to the gap where the ramp meets the coroplast. I wish I cut the coroplast door in the middle and make two swing out doors so They would swing out and meet the ramp.
