Care and Maintenance for Your Polyurethane Kitchen Countertop

Blog | November 26th, 2018

Polyurethane is a durable, resilient varnish that seals and coats wood with a cover that resembles plastic. It is excellent for use as a finish on cabinets and countertops, especially since it is not affected by acidic foods, beverages and cleaning substances. However, if you are not certain that the finish of your kitchen countertop is polyurethane, test the finish by applying a small amount of linseed oil to the surface, rubbing it lightly.

If the oil forms beads, the surface finish is hard and is not oil-based. Next, rub a small amount of acetone, such as nail polish remover, on a small spot of the countertop surface. If the surface is made of shellac or varnish, it will become sticky, and if it consists of lacquer, it will dissolve. If the surface of the countertop is polyurethane, it will repel the acetone, making it form beads on the countertop surface.

How to Care For and Maintain Your Polyurethane Kitchen Countertop

The best methods of caring for and maintaining your kitchen countertop made of polyurethane include the following practices:

• Removing Dust. – Remove dust from the surface of your countertop with a microfiber cloth that is dry. If corners and edges of the surface have dust accumulations, use a stiff nylon bristled brush gently for cleaning. If you have a vacuum cleaner with a brush attachment, this can also be helpful in removing all dust from the polyurethane countertop surface.

• Cleaning Grease and Grime Buildup. – By saturating a cleaning cloth with mineral spirits and rubbing it over the surface of your polyurethane countertop, you can clean away most of the smudges and dirt that can collect from daily use of a countertop. By applying a combination of vinegar and water in a similar way, you can remove many stubborn dirt or grease marks.

Vinegar has the capacity to break down grease buildups without causing any damage to the polyurethane. Also, when using vinegar as a cleaning agent, there is no risk of clouding the shiny surface of your countertop. For removing very stubborn stains caused by grease and grime, use a small amount of rubbing alcohol and a clean, dry cloth and rub the polyurethane surface thoroughly.

• Removing Stains. – To rid your polyurethane countertop of stains, rub the surface using a microfiber sponge. Many times, even stains from crayons and permanent ink markers can be removed in this way. If the stain has seriously discoloured the polyurethane, it is possible to resolve this problem by sanding the stain away with fine-grade sandpaper, wiping the surface clean and applying a new coating of polyurethane. After this coat dries, apply a second coat if needed.
