How do you care for these products ?

Cultured products provide an extremely durable, non-porous surface that resists staining.  Care is very simple.  Routine cleaning with a soft sponge or cloth, or non-abrasive aerosol foam cleaner is all that is normally needed to give many years of trouble-free service.  Harsh abrasive cleaners are neither required or recommended.  Mild abrasives such as automotive polishing compound, or baking soda, will remove simple scratches and stains.  Cigarette burns can normally be removed without noticeable effect.
