Rain Forest Green marble is a natural material: each Upside table is carved from a unique stone, so colour and veining will vary. Clean only with a soft microfibre cloth or a non-abrasive sponge, using glass cleaner or warm water with a mild detergent. Rinse with clean water and dry thoroughly. Never use solvents or abrasive/kitchen cleaners. Do not place hot items directly on the marble. Apply a marble sealant once or twice a year to protect against liquid stains. Upside marble and painted steel tables are intended for indoor use only, not outdoor.
