How to Remove Scratches and Restore Corian® Solid Surface Countertops

Understanding Corian® Solid Surface Finishes

Before diving into scratch removal, it’s important to know the type of finish your Corian® countertop has. Corian® Solid Surface comes in three primary finishes:

• Matte/Satin Finish (most common in residential kitchens)
• Semi-Gloss Finish
• High-Gloss Finish

The process for scratch removal is similar across finishes, but achieving a uniform look afterward requires attention to the specific finish of your surface.

Tools & Materials You’ll Need

• Mild soap and water
• Non-abrasive sponge or soft cloth
• Abrasive pads (such as Scotch-Brite™ pads – usually in gray, white, and green)
• Sandpaper (220 to 400 grit for deeper scratches)
• Orbital sander (optional, for larger areas)
• Water spray bottle
• Countertop polish (for semi-gloss or high-gloss finishes)
• Soft microfiber cloth

Step-by-Step: Removing Scratches from Corian® Solid Surface

1. Clean the Surface

Start by cleaning the countertop with mild soap and water to remove any debris or residue. Dry thoroughly with a soft cloth to ensure the scratch is clearly visible.

2. Assess the Scratch Depth

• Light scratches: Usually surface-level and can be removed with an abrasive pad.
• Deeper scratches or gouges: May require light sanding before using an abrasive pad.

3. Removing Light Scratches

• Use a wet gray Scotch-Brite™ pad (or a similar abrasive pad) and rub in a circular motion over the scratched area.
• Keep the surface and pad damp to avoid creating additional scratches.
• Blend the area by feathering out beyond the scratch to maintain an even look.

4. Removing Deeper Scratches

• Start with 220-grit sandpaper, sanding lightly over the scratch in a circular motion.
• Follow with 320-grit, then 400-grit sandpaper to smooth the area.
• Finish by using an abrasive pad to blend the sanded area with the surrounding surface.

Tip: For large areas, an orbital sander can save time and provide a more even finish.

5. Restoring the Finish

• Matte/Satin Finish: Continue blending with a gray pad until the area matches the surrounding surface.
• Semi-Gloss Finish: After using the gray pad, follow with a white Scotch-Brite™ pad to enhance the shine.
• High-Gloss Finish: Finish by applying a countertop polish with a soft microfiber cloth, buffing in circular motions for a uniform gloss.

Maintaining Your Corian® Solid Surface Countertops

To keep your countertops looking like new, follow these simple tips:

• Use cutting boards: Avoid cutting directly on the surface.
• Wipe spills promptly: Corian® is non-porous, but prompt cleaning helps prevent staining.
• Use trivets or hot pads: Though Corian® is heat-resistant, extreme heat can damage the surface.
• Clean regularly: A soft cloth with mild soap and water is usually all you need.
