Corian Countertop Tomato Stain
I laid tomatoes on the Corian countertop to ripen. They left a yellow stain that I cannot remove. Tried 409, vinegar, hydrogen peroxide. All to no avail.
Any surface can be stained if the right substance is left on the surface long enough. Corian Countertops
are "technically" not porous. That is what the manufacturer claims. However, staining does occur from common substances so the net effect is that Corian at least performs like a porous surface.
And most stains in Corian countertops are not
like stains in quartz countertops
where a chemical bleaches or discolors resins or polymers used to make the countertop.
Corian can stain from food or drink spills left on the surface and either absorbing or bonding in some fashion to the surface which makes the stains difficult to remove by simply wiping with a typical kitchen or surface cleaner.
How to Remove Corian Countertop Stains
Scrubbing with a mild abrasive like the Soft Scrub cleaner
is often successful.
Man-made surfaces like quartz countertops
can be difficult to repair but Corian countertops and other solid-surfaces can be repaired rather easily in most cases whether it's a scratch, burn, or stain.
First, try the Soft Scrub cleaner
but if that is not successful you can lightly sand the damaged area with 300 - 400 grit sandpaper or with Scotch abrasive cleaning pads
to remove the stain, scorch mark, or scratch.
Corian countertops are a consistent material all the way through the entire thickness so light sanding will simply remove the damaged surface material without leaving any noticeable repair mark.
