Use a clean, soft cloth to gently clean the accumulated dirt.
Gently wipe down the surface with a damp cloth and wipe thoroughly with a dry cloth immediately.
For stubborn stains, clean the surface using a clean soft white absorbent cloth dampened with a solution of mild soap and warm water. Then it should be allowed to dry quickly using a dry cloth or home dry cleaning products.
Do not use abrasive, acid, alcohol–based, or solvent–based cleaners; they may fade the finish.
Make sure cleaning materials are free of grit and other sharp edged objects in order to avoid chances of having scratches.
