How To Whiten/Brighten a Corian Sink

TheRVgeeks Annual Maintenance, Cleaning, Maintenance, Plumbing 7 Comments

Corian is a great material, but it isn’t impervious to staining and discoloring. Here’s a quick, easy tip for whitening a Corian or similar solid-surface kitchen or bathroom sink. Whether in your RV or in your house, this simple technique will rejuvenate even the dingiest and most discolored sink.

When our RV’s sink first began getting dingy and stained, we tried whitening it with bleach, which we’d heard was very effective. Bleach is just so smelly and toxic that we decided to stop using it.

Then our dear friend (and fellow RVer) Orene began waxing poetic about the wonders of Oxiclean. We’d originally been turned off by the in-your-face advertising for the product by pitchman Billy Mays, so we had never tried it before. Orene insisted we take a small ziploc bag of it back to the RV and now we wouldn’t be without it. Thank you Orene!

  1. Hey guys,
    You’re probably right, the only way to experiment with this is with the sink. Usually when we do the sink we add two large scoops of OxiClean to six gallons of water. That’s the approximate size of our sink. I’m going to try to do it next time with 1/2 as much.

    The next time I do the black water tank I’m going to use half as much oxy and see if I get the same result.

    Let me know if you try this especially after you clean your tank using ice cubes. I’m very interested.

  2. Your video on OxyClean helped us clean our Corian sink beautifully . It got me thinking, can we clean the black water tank the same way. We were having problems with our sensors. In the video it appears you use one small scoop for about a gallon of water. Its also worth noting that our sink holds about 6 gallons of water.
    To clean our black water tank we flush it a few times until it ran clear. Next I started filling up the black water tank via the sprayers. While that was going on I mixed up 30 small scoops of OxiClean in hot water and flush them down the toilet.
    (I don’t think it really matters but 15 scoops mix thoroughly in a 2 gallon bucket, 2x)
    I actually filled the tank until the full marker (F) came on and let it sit there for 4 hours.

    So that would be approximately 30 small Scoops to 40 gallons of water?

    I drained the black water tank and observed brown water rushing out.
    My empty (E) is now working.
    I flushed my black water tank after this experiment.

    This may be a great video for you guys to do or tell folks why they shouldn’t do it.
    My sensors a peer to be attached to the outside of the tank. Another thing in the video that would be great would be explained how sensors actually work.

    Thanks for the sink cleaning tip guys

      Hi David & Kathy! Glad to hear you got your sensor working again! We think it’s possible you might have used more Oxiclean than you needed to, since the stuff is pretty powerful & concentrated… but it’s great that it got the job done. We only used as much as we did for the sink because we needed lots of whitening action. Thanks so much for sharing your experience!

      Because we have a fiberglass roof, we don’t get black streaks on our RV. But our first rig (a Fleetwood Bounder) had a rubber roof, and we used a popular black streak remover like this one: Since we don’t use it ourselves, we aren’t recommending this particular brand, but it does have very good reviews on Amazon, and is the type of product you need. After cleaning the streaks off, the best way to keep them from returning as quickly is by keeping the roof as clean as possible (of course if you’re going to clean the roof, probably best to do that first, before cleaning the black streaks… always best to clean from the top down). ;-)
