Cleaning laminate countertops
To clean laminate countertops, start by removing everything from the surface. Use a dry sponge or brush to sweep away crumbs and debris. Then, take a non-abrasive brush or sponge, add warm water and a mild liquid detergent, and scrub the surface gently. You can also use a vinegar solution (mix 2 cups of water with 1 tablespoon of vinegar) to spray down the countertop and let it sit for 2 minutes before wiping it clean. For tough stains, create a paste with vinegar and baking soda and apply it to the stain. Let it sit for a few minutes, then scrub with a toothbrush or soft-bristled brush. Rinse and repeat as needed.
If your laminate countertop has scratches, you can use lemon oil or self-stripping waxes to help mask them. For glue residue, use a solvent like acetone and a non-abrasive cloth to wipe it off, then rinse with water and dry the surface. Avoid using harsh chemicals, abrasive cleaners, or bleach as they can damage the surface. Instead, opt for mild, non-abrasive cleaning tools and detergents to maintain the shine of your laminate countertops.

Repairing scratches
Before attempting to repair scratches on a plastic laminate countertop, it is important to assess the extent of the damage. Clean the area with a disinfectant if the countertop is especially dirty. Wipe down the spot with the scratch a couple of times to make sure the crevice is definitely clean. Use good lighting to determine the scratches' depth and breadth. Once you know how bad the damage is, you can decide on the best course of action.
If the scratches are light surface scratches, there are several easy and inexpensive solutions. One option is to apply furniture wax to the scratches. Another option is to use a high-quality paste wax or clear nail polish and remover (acetone) soaked into a magic eraser. Simply trace the scratch and then rub shortly after. You can also try rubbing a little oil into the scratch, but this is not a permanent solution and will need to be done frequently.
For deeper scratches, you can use a laminate filler such as SeamFil or FormFill. Choose a filler that closely resembles the colour of your countertop. Apply the filler to the scratch using a plastic putty knife, making sure to fill the entire length of the scratch. Remove any excess filler by scraping it off with the putty knife and then smooth the surface with the flat edge of the knife. Allow the filler to dry and harden for 24 hours, and then polish the repaired area with furniture wax for a seamless finish.
If the scratches are widespread or the countertop’s overall appearance has deteriorated, you may need to refinish the entire surface with new paint or a coating such as plastic laminate countertop paint. Clean the entire countertop to help the paint adhere to the surface and fill any deep scratches or dings using a two-part auto-body filler. When selecting a paint, choose a product that is suitable for a kitchen environment, such as Rust-Oleum Countertop Coating.

Using commercial polishes
Commercial polishes are a convenient way to restore the shine to your plastic laminate countertops. They are also an effective way to protect your countertops from scratches and daily wear and tear.
When choosing a commercial polish, opt for a silicone-free product, as silicone can cause buildup and lead to streaks and discolouration. You can also use a product specifically formulated for laminate, such as Hope's Perfect Countertop spray wax. This product is designed to enhance the shine and colour of your laminate countertop without causing streaks. Simply spray and wipe to apply.
Another option is Gel-Gloss, a cleaner/polish similar to automotive wax. Apply this product to your countertop, and once it dries into a light, powdery residue, buff it with a clean cloth to achieve a glossy finish. This process will also help mask minor scratches and create a smooth, water-resistant surface.
If your laminate countertop is made by Formica, it is recommended to avoid standard commercial furniture polish, as these products often contain chemicals that will cause streaking and discolouration. Instead, opt for a product specifically recommended for Formica, such as Hope's Perfect Countertop.
In general, it's important to avoid wax-based products when polishing laminate countertops. These can leave behind a residue that dulls the surface over time and attracts dust, leading to unnecessary wear and tear.

You can also use mild soap, glass cleaner, or a mixture of vinegar and water to clean the surface. For stubborn stains, a paste made of baking soda and water can be used. Commercial laminate polishes are also available, which can fill in minor scratches and imperfections.

Painting laminate countertops
Before you begin painting, use painter's tape to cover any areas adjacent to the countertop, such as the sink, cabinets, refrigerator, stove, and walls. Lay down drop cloths or old sheets to protect the floor and any nearby furniture. Remove any items stored on the countertop and clear the area completely. Painting can release fumes, so it’s crucial to work in a well-ventilated area. If possible, open windows and doors and consider using fans to circulate air. If ventilation is limited, take frequent breaks and wear a respirator mask designed for painting projects.
Next, you need to prepare the countertop surface. Start by thoroughly cleaning the countertop surface. Use a degreasing cleaner to remove any built-up grime, oils, or residues. This step is critical for proper paint adhesion. Rinse well and allow the surface to dry completely. Then, lightly sand the entire countertop surface with medium-grit sandpaper. The goal is not to sand through the laminate, but to create a slightly rough surface for the primer to adhere to. Use a sanding block or palm sander for large areas, and hand-sand corners and edges. After sanding, wipe away all dust with a tack cloth or a rag dampened with mineral spirits.
Once the surface is prepared, it's time to start painting. Start by pouring some primer into a paint tray. Then, using a roller in a back-and-forth motion, apply it in thin, even coats to the laminate counter. Allow the primer to dry completely before applying your chosen paint colour in the same manner. It is important to follow the instructions on your chosen paint and to allow adequate drying time between coats.
Finally, finish the project with a sealant. Apply a layer of sealant to the surface and sand it lightly once it dries. Repeat this process two more times, applying sealant and sanding until smooth. Apply a final coat of sealant and let it dry for 24 hours to complete the painting process.
