How to clean badly stained white corian sink?

Bought house in which previous owner severely stained the white kitchen sink. My guess would be coffee dumped daily into the sink. Like for 5 years. Settlement was yesterday and I have tried several things with only minimal improvement. Soft scrub with bleach. Hydrogen peroxide. Baking soda and vinegar. Green scotch brite scrubber. Bar keeper's friend. Lots of elbow grease. Soaked overnight in cascade granular dish detergent. Some improvement noted.... but still very noticeably stained. Help!

Pity you did not make cleaning it up so no stain showed a contingency in the offer - because this would normally be considered a must-do on an inspection, given the difficulty of deep cleaning Corian.


Here are links to the DuPont care and cleaning info -

Here is an article on the specific brown stain subject -


" target="_blank">https://www.washingtonpost.com/life>


Ordinarily, 409 or scratchless Comet will do it, but for deep staining probably going to have to be abrasive ground - normally done using a flexible rubber backing disc on a palm sander under about 80 grit silicon carbide standpaper then working to finer and finer - then resealing after it is through the stain, if it goes that deep.


You could also try TSP on a wet rag - plug the drain opening while scrubbing, then flush with ample water when done. Should not hurt the pipes at all but I am not sure about garbage disposal - hence the plug suggestion. OK to use white veinegar as the rag wetting agent plus TSP powder on the rag or shaken onto wet surface like you would with Ajax (which might also work - the regular Ajax, not the safe for porcelain stuff.


Some people have said denture cleaning tablets (several to half a dozen in a sink full of warm water) work also. Some say Mr Clean Magic Eraser or Barkeepers Friend powder (the bar will scratch grooves in it because of the curves).


IF there is a chance this is staining from hard water, try LimeAway.


Sometimes heavy bleaching is necessary as part of the process if the stain has really penetrated. First try Comet or Soft Scrub with Bleach - if that does not do it, then what I have used (on pure white Corian only) is 50% chlorine bleach in water, on a rag that is draped over the edge of the sink NOT touching chrome or faucets or such) and let sit in direct contact against the brown surface. You have to be sure to evenly bleach the surface, and you do NOT want it going down the drain and sitting for a time so build a plug in the drain with a rag. Try 1 hour contact time first, increase or redo if necessary. not guaranteeing it will work if stain is deep. DuPont says up to 16 hours is safe - but I certainly would be sure the bottom is firmly plugged if leaving for an extended time, and try to keep the rags (or paper towels) just wetted, not dripping to minimize leakage into the pipes till ready to flush it out.


Any time you try something like this in a sink or such, be sure to seriously block off/cover to keep kids and pets out, of course.


Note anything abrasive that is used will remove the sealer, so you would need to reseal it after cleaning, and fine abrasive polishing as needed.


A Countertop contractor who routinely works in Corian can do this refurbishing for you - I would say probably about $250-300 for one side, $300-350 for two sides if both are heavily stained - including resealing afterwards. Make sure any chrome or trim is fully protected with heavy tape during the process so it does not get gouged or scratched.

Mr Clean Magic sponges - you'll need more than one, but it worked for me.
