Sanding Corian (or other solid surface materials) requires a progressive, multi-step process. Use a random orbit sander for the main areas, moving from coarser to finer grits while wiping away dust between each step. Finish the surface with non-woven pads and automotive compound for a polished sheen.
If required remove surface blemishes, fabrication scratches, etc., using the 100-micron film abrasive on an orbital sander. This step is done dry. Wipe surface of the countertop completely clean and inspect for defects and scratches. Sand again if needed.
To make your Corian (solid surface) countertops shine, you will need to remove micro-scratches and dullness by sanding them smooth and buffing with a polishing compound.
Depending on depth of scratches begin sanding with 120 or 150 grit paper. It is important to follow the sanding path “North – South, East – West” as detailed below for each sanding step. Sand with 180 grit and clean top with denatured alcohol or water. If scratches remain, Repeat Step 3.
Keep nail polish remover, bleach, detergent, permanent markers or inks, and oil soaps away from your Corian® Quartz. Heat Damage Prevention - To maintain the beauty of Corian® Quartz, do not place hot skillets or roasting pans directly onto the surface. We recommend the use of trivets and hot pads.
Consequently, this material often looks more commercial than “homey” to a lot of people. In terms of durability, Corian tends to be more easily damaged by hot surfaces than natural stone. It's also more prone to scratches than surfaces like quartz and granite.
You can use a Magic Eraser on Corian, but use it sparingly and only for stubborn stains or marks. Because a Magic Eraser (melamine foam) is a micro-abrasive, frequent or heavy scrubbing can dull the surface or alter the sheen of your solid surface countertop.
Yes, you can easily buff out scratches on Corian (solid surface) countertops. Because Corian is solid all the way through, you can sand and polish the surface to make it look brand new.
Personal Preferences: Ultimately, style is subjective, and individual tastes vary widely. Some consumers may simply prefer the visual appeal of other materials over Corian, irrespective of its practicality, leading to a decline in its perceived stylishness among certain demographics.
Applying Excessive Pressure
Pressing down too hard on your sander is a common mistake. It can be tempting to apply more pressure to speed up the process, but this can create swirl marks, cut-through, and uneven sanding. Excessive pressure also generates heat that causes premature loading of your abrasive discs.

Light colors: Use P240 grit sandpaper or 60μ paper to remove scratches. Wash and follow by P400 grit or 30μ paper. Wash to remove residue, then follow by buffing with a Scotch-Brite ™ 7448 S ULF (gray) pad in a circular motion. Dark colors: Use P240 grit sandpaper or 80μ paper to remove scratches.
Corian countertops typically last 30 years or more with proper maintenance. While the brand includes a 10-year residential warranty, their non-porous, homogeneous acrylic solid surface design makes them highly durable, non-fading, and completely repairable.
Sanding solid surface countertops (like Corian) is an excellent way to erase scratches and restore the factory finish. Use a random orbital sander and sequential grit changes, starting with a coarse abrasive like 120-grit for deep scratches, and progressing to finer grits until your desired sheen is achieved.
While a brand name, Corian has become a generic term for all solid surface materials made from a combination of polymer and natural minerals. It is notably more affordable than quartz and other high-end countertop options, making cost-effectiveness one of its primary selling points.
Corian countertops are a seamless, non-porous solid surface, but they are highly susceptible to heat damage, prone to scratches, and do not offer the same resale value or natural depth as premium stones like quartz or granite.
If you have soft surface countertops like granite or marble, step away from the magic eraser. You can use them on laminate, Corian, quartz, and other solid surface countertops, but do a spot check.
WD-40 doesn't actually repair scratches, but it is excellent at temporarily hiding very light surface marks and removing paint transfers (like when another car scrapes yours). It works by acting as a lubricant and temporarily filling in the scratch or dissolving the foreign paint.
Nail polish. Use a microfiber cloth and rub the stain with acetone-free nail polish remover. Rinse several times with warm water and wipe with a dry cloth.
Although liquids cannot penetrate Corian®, it is best to wipe up spills as they occur. Just use a damp cloth and a mild cream abrasive cleanser or a common household degreaser (e.g. Jif, Bar Keepers Friend).
Yes, you can use Clorox wipes on Corian countertops for occasional disinfecting, but they are not recommended for daily cleaning because they can leave a cloudy residue. For regular maintenance, use warm soapy water or an ammonia-based cleaner, and avoid using harsh abrasive cleaners or letting wet wipes dry on the surface.
Luckily, everything you'll need to clean your hard surfaces can already be found in your home: Concentrated dish soap that's tough on stains and grease but gentle on stainless steel, granite, and glassware, like Dawn® Platinum Plus Powerwash Dish Spray. Soft cloth or sponge. Water.
