Corian Countertop Tomato Stain

by Lois

QUESTION:

I laid tomatoes on the corian counter to ripen. They left a yellow stain that I cannot remove. Tried 409, vinegar, hydrogen peroxide. All to no avail.

ANSWER:

Any surface can be stained if the right substance is left on the surface long enough.

Corian Countertops are porous, so staining is possible. Like stone and quartz, stains and damage occur below the surface where regular cleaners won't do anything to remove the stain.

Man-made surfaces like quartz and Corian solid-surface tend to be more difficult to repair than stone and damage is far more often permanent, but following the procedure outlined in the Removing Granite & Marble Stains e-book will work on any porous surface unless the stain is old or too deep.

corian does not stain
by: Jon Olson

Corian is a non-porous surface. I suggest you use soft scrub .

Corian does not stain-- well actually it does
by: Ryan

Jon,

Corian is essentially "non-porous" relative to other materials, but it does have pores. Corian is very stain-resistant.... not stain-proof.

The manufacturers of quartz and solid surface countertops do market their products to give the consumer the impression that it is impossible to stain a quartz or Corian countertop... but that is just not true.

Quartz CAN be stained and damaged. Corian CAN be stained.

Soft scrub may work if mostly on the surface. Or you can also try light sanding, which is possible with Corian to remove scratches and light shallow stains.

Corian-Stain Resistant
by: Anonymous

We have been solid surface fabricators for over 15 years. Corian is nearly impossible to permanantly stain. We have not come across a problem that we were unable to fix yet. All you usually need to remove any stain is a scotch brite pad or soft scrub. If you are having trouble you can call a certified professional to come sand out the stain. Remember Corian can be resurfaced, and is completely repairable and renewable.

The idea that a stain can't be removed is often stated by countertop companies that want to sell you granite. However if you stain your granite, which is completely pourous, there is very little you can do to remove it.

RE: Corian-Stain Resistant

Hey Anonymous,

Thanks for your insights on removing Corian stains.

We certainly don't state that Corian stains can't be removed... just that Corian can be stained despite marketing that would have you believe otherwise (same deal with quartz).

And any countertop company that is advising a client on which surface to install should recommend granite over corian.

Granite is more expensive, but granite (or quartz) is a far better surface for the kitchen (where you want the most durable low-maintenance surface) than corian is. There is no deception recommending granite over corian when considering performance only.

If cost is the most important factor, then I'd recommend laminate over corian myself. You get similar performance for far less and from a design perspective laminate has essentially caught up to corian.


I do have to correct you about your statement regarding granite stains....

Granite is a natural material so you can't make a 'general' statement about performance. Some granite is very porous. Some is moderately so and many granites are still porous, but essentially non-absorbent because they are so dense.

Such dense granites are virtually stain-proof and certainly the most stain-resistant surface you could install save maybe stainless steel.

The idea that ALL granite is absorbent and must be sealed is false.

So yes, granite can stain, but contrary to what you state it is almost NEVER permanent. Only neglected stains that are very old and deep will be troublesome, but even then you can re-surface the stone to remove the stain and bring the granite back to like-new condition if desired.

And remember, nobody "owns" or "makes" granite so there isn't any creative marketing needed. It's the man-made products that need to somehow try and "sell" a story that their surface is better than granite... no one has been able to do that yet.

We do our best to tell our visitors the whole story minus the marketing biases and claims.

Way off with the "facts"
by: Jeffrey Purcell

Where did you get your facts? Your comments pertaining to granite out performing solid surface and your comparison liking solid surface to laminate are absurd.
Unfortunately, any statements posted on the internet with level of eloquence will be believed by some. What a load.

Facts
by: Ryan

Jeffery,

Thanks for your participation. I take it you are in the industry, although your comments are a bit surprising, since I can't imagine why or how any fabricator could ever argue that Corian performance somehow compares favorably with granite.

Such a fabricator would be considered an inexperienced, ill-informed novice or possibly heavily invested in selling corian.

When Corian first came out it was thought it may rival granite. Of course, every professional who worked with both quickly found out that was not true.

Most granite will easily outperform corian.

Some granites are very porous and will stain easily (although stains can be easily removed). Corian won't stain easily and stains can be removed as well.

But no man-made product has yet to better the performance characteristics of the best granites, which are very dense and essentially stain-proof, do not scratch, do not etch and can take heat easily.

Quartz offers nearly the same performance, except when damaged it cannot be repaired as easily as granite.

However, Corian isn't close enough to even be in the conversation. And here's the facts:

1. Corian scratches easily.... granite does not

2. Corian cannot take heat.... granite takes heat easily

These two facts easily put granite on top especially for a kitchen countertop.

Neither stain easily, but as stated some granites are basically stain-proof, which is a fact (#3)... and you know that Corian is not.

Again, this is not true of all granite, but it is very easy to choose a granite that is nearly imposible to stain. So, when looking at 3 of the most important performance characteristics... granite wins. No contest.

Corian has an advantage with the capability to install without seams, but that is truly the one and only advantage Corian has over granite.

And comparing Corian with laminate is far from absurd.

Both laminate and Corian can be scratched. Neither can take the heat. Both are fairly stain and chemical resistant although both can be stained. So, essentially the same.

Corian has an advantage that it can be repaired and laminate typically cannot, however, laminate is also waaaaay cheaper than Corian.

So, Corian does make a more durable surface than laminate, but dollar for dollar laminate is easily a better value.

Some may argue style vs. both laminate and granite, but that has nothing to do with performance.

And you are right about opinions on the internet. Eloquence (even when wrong) can be convincing for some people just like sarcastic, superscilious, rude, arrogance is sometimes mistaken for knowledge.

You claim that "facts" are missing, yet you present none to support your "opinion".

We welcome all voices and comments. However, if you wish anyone to take you seriously, then present some evidence or at least a reasoned argument to support your position.


corian stains
by: PROJECTPERV

Yep....it stains. The wife made salad and the red onion rolled off the cutting board and it rested on the seashell color corian countertop for a few hours and made a mild yellow stain.
I used 1/3 water with 1/3 white distilled vinegar and let it sit for 30 minutes and it faded out at 85%
Going to use a little soft scrub and see If the remaining 15% comes out. Happy Memorial Day everyone

"But the salesman said!"
by: Anonymous

All man-made countertop surfaces are impervious to stains -according to the person who sold you the new counter-top- except for the fact that pretty much all of them stain instantly if you get so much as a single drop of hot-sauce, tomato sauce or coffee on them and don't wipe the stain off within about 3 seconds.

Likewise, all of these materials resist burns from hot pots and pans, so long as you keep all of those pots and pans on the stove and off the counter-tops.

A pot or pan that's sitting on the stove will not burn a Corian counter-top. However, if you take that pot or pan off the stove and set it on the Corian counter-top you will have an instant burn mark.

Not to worry, because Corian can be repaired so that you'll never know there was any damage, except for the fact that it can't really be repaired, and you can only kind of/sort of hide the damage but will always notice the pattern in the material looks a bit off on the spot where you had the burn.

==== Countertop Specialty Comment:

The hyperbole is amusing, but I certainly understand the sentiment.

Man-made surfaces like Corian countertops and quartz countertops are generally excellent choices and perform well in general use.

However, the marketing does tend to lead consumers to believe that they are nearly invincible and have conquered all the faults of natural stone, etc., when in fact, these countertop materials can be damaged and stained, do have their unique problems and limits like all other countertop materials: wood, concrete, marble and granite.

We do our best to enlighten consumers regarding this issue and not expect any surface to be impervious to damage.
