For a thorough deep cleaning of your LIND DNA Placemats and glass mats have Lind DNA The Deep Cleaning Soap developed, a liquid soap, specially made for cleaning products in recycled leather. Easily dilute the soap into a little water and carefully wipe the mats with a sponge so that the soap can foam. Then remove the foam with a damp cloth. With heavy cleaning, let the foam sit on the product for a few minutes and remove it with a damp cloth.
