We applied a thin layer of matte and colorless varnish to protect the stool from small splashes of water or other. To clean the stool you can take a very slightly damp cloth and wipe it over the bench. If over the years you want to give a new look to your stool which has naturally weathered, you can sand it lightly. This is the advantage of a solid piece of furniture, it is made of solid material. We strongly recommend that you varnish it again or oil it; also, choose products that will not tint the material if you want to keep the same color of the wood.
