Monika asked: How do I clean a white Corian kitchen sink? I have had the sink now for 10 years. The sink is a seamless part of the Corian countertop. The sink stains don’t come out with regular kitchen cleaners. I have also used bleach without success. Any recommendations?
To 
keep Corian looking its best, wipe up spills as soon as they occur and avoid prolonged contact between Corian and anything that might mar or discolor the surface. Even the most diligently cleaned surfaces can still have trouble, though, so whether you have stains or an overall dinginess, you should be quite happy with the boost your Corian will get from this simple cleaning process.
You Will Need:
- Bar Keepers Friend
- Cloth scouring pad
- Water
- Dry towel
Steps to Remove the Marks:
- Wet the surface to be cleaned
- Sprinkle a heavy coat of Bar Keepers Friend over the wet surface.
- Use the scouring pad to work it into a paste. Ensure the entire targeted area is coated.
- Allow it to sit for a few minutes, but do not allow the paste to dry on the surface.
- Rinse the scouring pad and begin working it over the surface.
- Once the Corian is clean, rinse thoroughly with water. Ensure all of the residue is gone.
- Dry with a towel.
Additional Tips and Advice
- Bar Keepers Friend is a scouring powder that can remove a wide variety of stains from your Corian sink, including beverage stains like coffee or tea, various food stains, cooking oil, and even hair dye, as well as general dirt and grime.
- Soft Scrub is another cleaning product that provides consistent, good results.
- One site user (Thanks!) has reported success by filling the sink up with hot water, adding some dishwasher detergent and allowing it to soak for about 10 minutes.
Have you tried baking soda sprinkled on dry, then scrub with rag or sponge?
Another option is Quick Eraser by ScrubIT; comes in a two pack; sponge is blue on one side, white on the other. Just wet the white side and rub on the stain. It’s remarkable what this product removes! It’s taken fruit stains off my countertop, but won’t work for rust stains very well. I got mine at the dollar store.
Comet works great! I have the same sink!
Our Corian double kitchen sink was installed in 1996. One sink is very badly stained and we have tried everything to try and clean it, but without success.
Can the sink be resurfaced?
Charles,
Yes; a Corian sink can be resurfaced to remove stains. Determine the ideal sandpaper grit for your sink type (matte/satin, semigloss or high-gloss) with the Corian Care article by Kitchen Source.

Barkeeper’s Friend is very good at removing most food stains, and works especially well for scouring out metal and mineral stains, such as iron rust and scuff marks from steel and aluminum cookware. However, it is slightly more abrasive than scratch-free cleansers and can dull the polished surface of Corian if used on a frequent basis. I’d avoid using Barkeeper’s Friend on glossy Corian Countertops, but in white Corian sinks, a matte finish is more acceptable and is a small sacrifice to achieve a stain-free appearance.
Scratch-free Comet can be used daily in Corian sinks, with no adverse effects. Comet has the added benefit of containing chlorine bleach, which can kill germs and dispel the odors they cause, and restore the sink’s whiteness as well.
One of the most effective stain removers I’ve ever found for Corian is also the least toxic: hydrogen peroxide, which is so mild it is often used as a mouthwash, and can usually be found in the pharmacy aisle of stores, displayed on the shelf beside the rubbing alcohol. Hydrogen peroxide does work more slowly than other cleaners, but over time it can do a surprisingly thorough job eliminating even stubborn stains. On its own, hydrogen peroxide will be too watery to stay in place on sink surfaces, but if you make a thin paste with a few drops of liquid dish detergent and a mild cleanser like Bon Ami (or even simple baking soda), it will adhere to the sides and bottom of the sink without flowing down the drain. This homemade hydrogen peroxide paste can be left on for hours overnight, and can even be allowed to dry — because it will always rinse away easily and won’t mar or scratch your Corian — but the best results of all will be obtained if you keep the paste wet, by covering the sink surfaces with plastic wrap, for instance. Several bad stains that I never thought I’d be able to remove from Corian were lifted by using this technique, though repeat applications will sometimes be needed. If you practice diligence at this, your efforts should eventually be rewarded with a completely white, blotch-free sink. (Don’t use chlorine with hydrogen peroxide, because they’ll neutralize each other, and you’ll defeat your purpose.)
A final suggestion: alternating the cleansers you use can also work well, when stains persist. If one of these three cleansers doesn’t work on the first try, the other two treatments usually will.
I have the same problem and Comet with bleach won’t touch it. I guess I’ll try Barkeepers Friend and if that doesn’t work, maybe automotive buffing compound?
Here’s a fantastic solution — no scrubbing required.
1. Spray sink thoroughly with Oxi-Clean liquid laundry stain remover.
2. Sprinkle sink immediately while wet with Oxi-Clean “White Revive” laundry stain remover powdered detergent so the mixture remains wet.
3. Let stand overnight.
Rinse thoroughly the next morning.
The stains are gone!
(Severely stained sinks may need a second treatment.)
Sunlight Dishwasher Detergent takes out all stains. You put it directly on the stain and let it sit a few minutes. I put it on pretty heavy and then when I’m about to clean it, I spread it all around the sink and let it sit a few more minutes. You can actually see the stains go away and you can see where you missed a spot.
I see several kinds of Bar Keepers Friend – which once is the best for a white coriander sink? Foam spray, or powder, or another kind?
