Corian sinks and counters are durable and easy to clean–until they are stained by rust, turmeric, or your kids’ mystery projects. Use this natural recipe to remove stains from your Corian or solid-surface counter or sink!
The original kitchen in our house was a true testament to the 1970s. Multicolored linoleum, Formica countertops, dark wood cabinets, and a light tan sink that always looked dirty, even when it was clean.
When we remodeled, we chose generic Corian (also called “solid surface”) counters. We love the vibrant blue color with flecks of black, white, and gray—and chose a built-in white sink made of the same material.
The countertop is sturdy, heat-resistant, and scratchproof, which are all great qualities in a counter! However, this means that if it gets stained, it’s VERY hard to clean.
How do I know? Because our cast-iron wok sat in the sink while we were out of town recently. The sink had a nasty rust stain as a result.
I tried everything I could think of to get the rust out.
Homemade soft scrub didn’t work.
Bon Ami didn’t work.
Even my beloved Lemon essential oil didn’t work.
We don’t own chlorine bleach…and even if we did, I wouldn’t want it in the sink where we prepare our food. I was at my wits’ end, and was thinking about scrubbing the stain off with super-fine sandpaper.
With all the homemade cleaners in my house, there had to be something I could make, right? I tried lots of combinations and was thrilled with this easy solution for cleaning Corian.
Natural Corian Stain Remover
This combo removes stains without using bleach or strong chemicals. We have a white sink, so it didn’t affect the color—but if you have a colored sink, test it in a hidden area first to be sure.
Mix this recipe up as needed—don’t try to store it for later.
Ingredients
¼ cup baking soda
2-3 Tablespoons hydrogen peroxide
Instructions
Mix baking soda and hydrogen peroxide together to make a paste. Spread onto the stain and let it sit for up to 24 hours. Scrub gently while rinsing, and repeat if needed.

Our home came with a stained Corian sink (brown/orange stains). I applied this paste overnight and it absolutely works. Rinsing it in the morning revealed a distinctly pale area with a well-defined border coinciding with the application area.
I’ve been applying it every night for a few days, and while the sink doesn’t look brand new, the stains are mostly gone. In a few places where there are physical grooves in the surface some stains remain. I might try to sand them away, but it’s fine as it is.
Thank you!
The baking soda combined with hydrogen peroxide did not work to remove the rust stain in my corian sink.
Thanks for this tip. I’ve had brown marks on my white corian sink for ages. The baking soda & hydrogen fixed it. Left it on for about 4 hours then rinsed.
stain from Red Gatorade drink
WOW! this worked! and nothing else did. thank you so much! my sink had brown black stains that wouldn’t come up. now it looks like new!
I think that what CAUSED the stain would affect what might REMOVE the stain.
I think ours was coffee, but I don’t know for sure, so I’ll keep trying different suggestions, ’til I find the right combination.
I just used a little paste of baking soda and water on my corian top…left on for a few minutes and then wiped it off. Worked fine.
Baking soda and water did nothing for me.
Baking soda and vinegar did better but I need more power for our coffee stains.
I didn’t want to risk discoloring our beige sink OR waste Peroxide, but I’m gonna try Pam’s formula next.
Wish me luck!!!
Oh… and a a Mr Clean Magic Sponge, with ALL of the above!
I spilled paint thinner on my countertop! The spot is apprx 4 x 8 inches. It is much lighter than surrounding area. Can this be fixed?
The issue I’m having is that my dark grey corian counter top was “damaged” by a cleaning service by something they used to clean the cabinets and stovetop. Lots of spray and drip marks. I’ve tried everything and nothing works. My husband thinks the top finish must have been damaged. Any ideas how to fix this?
I clean my white corian with a Mr Clean sponge. It works fabulously!!!
I tried one of those and NOTHING 🙁 Was very surprised, it was the first time it didn’t do the job.
I am going to try this. But I thought I would show another solution. Even easier. Works very, very well. And I’ve tried about everything including paste, bar keepers friend, etc. And this is by far the easiest.
Get some OxyClean.
Fill the sink about an inch with very hot water.
Put 3-4 tablespoons into the sink. Mix it around so it disolves.
Wait about 8 hours, longer if you wish.
Drain the sink, rinse.
Observe the results.
I did the test 1/2 sink with baking soda and Peroxide and the other half with baking soda and vinegar! The vinegar side won, hands down! Took pictures too, but can’t post it!
I had a corian sink one of my tenants was using curling tongues and died her hair red it left two red lines on the marble like sink. I tried everything but I had not tried vinegar and baking soda, so i did and used wire wool, and to my amazement it disappeared took about 30 to 40 rubs but it completely disappeared and the counter top looks perfect again – thank you so much!
glass ring on my counter top can not get it out?
I have no problem using bleach. In fact, I’ve used it the last few years on my light tan Corian sink. It’s more than 10 years old, and the stuff that used to disappear instantly with a bleach/water soak is getting more stubborn. I recall a Corian technician saying that sanding it with the finest grit sandpaper would be fine. He had a large, roundish, flower-shaped sander that I’ve NEVER been able to find at any hardware store.
You’re looking for a resurfacer/polisher. Makita makes one, but they are not cheap.
I had a coffee stain in my sink for several months. I tried Soft Scrub, Barkeeper’s Friend, and steel wool. Nothing worked. I read this blog and ordered the Iron Out. In the meantime, I tried the hydrogen peroxide and baking soda, and that did the trick! Thank you for the tip.
I had a stain on a light tan corian countertop. I tried baking soda mixed with a little white vinegar and rubbed the stain, for no more than 30 seconds and the stain is virtually gone!
THESE INSTRUCTIONS OF BAKING SODA AND HYDROGEN PEROXIDE DO NOT WORK!!!!!!!!!!!!!!!!!!!!!! NOT EVEN A LITTLE BIT!!!!!!!
I used the baking soda & peroxide method & it was great — as good as bleach & way less toxic.
Carolyn said, “The Corian cleaning recipe works GREAT”. Well, which of the Corian recipes worked great??? They recommend a bunch of things and none have worked for me.
That’s great, Carolyn! I’m so glad it worked well for you.
This corian cleaning recipe works GREAT! I had an awful stain and and it got rid of 90%; the key is patience. If I had let it sit overnight instead of just for 2 hours I bet it would be all gone. I did cover it with plastic wrap. THANK YOU!!!!!
I was disappointed to find that our new white corian sink looked stained after we were done doing the dishes every day. I’ve been scrubbing it with oxy & a green scrubbing pad, but now I realize the surface has become rough & even more susceptible to staining. Is there a way to sand it smooth again?
Light brown stains can be caused by tea or coffee. To remove them, try a scrub powder with oxalic acid, such as Bar Keepers Friend or Zud. If that isn’t enough, use bleach in water. In its advice about disinfecting Corian surfaces, DuPont recommends using a solution of half bleach and half water, so even that strong a solution should be okay for removing stains. Or you can use a product that has bleach included, such as Comet Cleaner With Bleach or Soft Scrub With Bleach.
I have stains caused by hydrogen peroxide on my white corian benchtop from where the spa cleaner sat. Any suggestion how t get them out? At my wit’s end!
