RECYCLED PET For cleaning recycled PET surfaces, we recommend using a soft microfiber cloth slightly dampened with lukewarm water and a mild detergent. Avoid abrasive products, harsh solvents, pure alcohol, or rough sponges, as they may compromise the material’s matt finish. For more stubborn stains, use a solution of water and mild soap, rinse with a clean cloth, and dry thoroughly. Do not expose the surface to direct heat sources or prolonged humidity in order to preserve the material’s integrity and durability.
