Never cut directly on a countertop (use a cutting board ).

Don't place anything directly from the oven or stove onto the surface. Use hot pads or trivets with heat generating appliances.

Avoid cleaning products that contain harsh chemicals or solvents like oven cleaners, paint and stain removers, drain cleaners and acetone.

Don't use your countertops as a work bench or stand on top of them.

To clean use a damp cloth or sponge and a mild soap or detergent. Difficult stains such as coffee or tea can be removed using a mild household cleaner and baking soda mixed to a paste and a stiff nylon bristle brush scrubbing approx. 15-20 strokes. Do not scrub so hard as to mar or scratch the surface finish.

Hair, textile and food dyes can cause permanent stains. If dye should happen to spill, wipe it up immediately with dishwashing detergent or an all-purpose cleaner.

Don't leave standing water around joints or seams.

Steel wool and other abrasive pads will damage the laminate face. Do not use them for cleaning and don’t store steel wool pads on your countertop; the metal can rust and leave stains.

Remember, sharp objects can damage the surface of laminate, marring its beauty and lowering wear and stain resistance. Although high pressure laminates are somewhat resistant to scratch and marring, the surface can be damaged, even under normal use.

Laminate may need occasional dusting depending on where it’s used. To keep the surface beautiful, use a non-oily furniture spray. (Remember to clean the spray off several times a year to prevent build-up.) Furniture polish can also help hide fine scratches in the surface.

A damp cloth and mild soap is usually all that is required to clean a solid surface countertop. Non-abrasive household cleaners such as Fantastik® and Formula 409® may also be used for regular cleaning.

For matte finish solid surface countertops you can use an abrasive cleaner like Ajax® or Comet® with a Scotch-Brite® pad to remove tough stains, minor cuts and scratches, and cigarette burns. Use a wet Ultra-Fine Scotch Brite Hand Pad (#7448) and rub in a circular motion, then clean with soap and water. For deeper cuts, hand sanding with 400 grit sandpaper will usually work. The next step would be to use heavier grit paper with an electric sander.
To add additional shine to your countertop apply a non-wax polish cleaner to a dry surface and wipe clean. 

Surfaces with gloss and semi-gloss finishes will require more maintenance than matte or satin finishes. Countertop Magic or Plexus are good polishes to use to enhance the shine. Abrasive cleaners like Comet®, Soft Scrub® etc. should not be used on glossy surfaces except for removing tough stains, minor scratches, and burns. Keep in mind that whenever you use an abrasive product on a gloss finish it will affect it.

As a general rule, try not to pour hot boiling water or put hot pans directly into a solid surface sink, if you have to then run the cold water simultaneously.
