Zachary A. Design furniture is made of fiberglass and stone. Some wear and fading over time is normal. This does not take away from the rustic texture of the material. It is made to look natural. To clean use only water and a soft sponge, or cloth to wipe any dirt that may have collected on the surface. A matte clear coat covers all pieces to aid cleaning. Harsh abrasives and solvents could dissolve the protective coating over time. Household soap and soft scrubbing with a nylon brush can be used to clean dirt from time to time, but is frequently not necessary. DO NOT POWERWASH. Do not use abrasives to clean any of our pieces. If a problem spot or stain arises some scrubbing with a light non-solvent soap will get spots out.
