    Restoring Your Solid Surface Sink

    Solid surface acrylic resin countertops have captured the hearts of homeowners for years. Along with these countertops came solid surface sinks. These sinks are typically mounted under-mount but may also be integrated directly into the countertop. Another variety of solid surface sinks are top mounted.

    Solid surface acrylic resin sinks and counter tops are made by different companies and have various names such as Corian® Wilsonart® Formica® Avonite® Staron® and so on. However, these acrylic...MORE resin materials are not the same as quartz solid surfacing like Cambria® or Zodiac®.

    But as much as these solid surface materials provided an option to granite tops and stainless steel sinks, they lose their luster over time and use. Sometimes the solid surface tops can crack and need repairing, but most often the sinks just become dull looking and dingy.

    Come on, that's not the look you fell in love with, was it?

    So why do sinks get dull looking? Well, solid surfacing is non-porous so stains can’t penetrate the surface and take hold. But what can happen is that over time, the smooth luster of the solid surface sink gets dull due to the abrasion of dishes and metal pots and pans.  Also, thin layers of built-up food “gunk” may begin to adhere to the roughened surface.

    I asked Michael Chotiner, a master carpenter and writes about some home improvement projects, to provide some advice on how he restored his solid surface sink. If you find that you want to look for a new kitchen sink you can try big box home improvement centers who carry a wide variety of sink options.

    To restore your solids surface sink back to its original luster,  all you need is:

    • An abrasive cleaner like Comet®, Ajax®, Bar Keepers Friend®
    • An abrasive pad
    • A small bristle brush

    There are options to these cleaners of course. DuPont says to use an ammonia-based cleaner, others recommend Soft Scrub® or bleach or hydrogen peroxide, Mr. Clean Magic Eraser® or baking soda and salt.

    But in the end, all you need is Comet® with Bleach and some patience.

    Gather Required Supplies

    Gather the recommended items seen in the photo above.

    • An abrasive cleaner with bleach
    • Scotch-Brite® yellow/green sponge
    • Scotch-Brite® abrasive pad (if you need deep cleaning)
    • A small plastic bristled brush

    You can also use some Scotch-Brite Heavy Duty Greener Clean pads which are made with agave fiber and are supposed to be more environmentally friendly than their standard product.

    Spread the Cleaning Powder

    Wet the sink and spread Comet with Bleach all over the sink basins. Leave the wet powder on the surface for a couple of hours so the bleach will have some time to act on the caked on food gunk.

    Scrub the Sink with Cleanser

    Scrub with the green Scotch-Brite backing on the sponge (it’s wise to wear gloves and protect your hands when working with cleaners if you want them to stay looking good). Then, apply the bleach cleanser in two layers, and scrub with the heavy-duty brown scrub pad.

    In the case shown here, you will see a problem that could not be scrubbed away. That is scratches to the left of the drain.

    Scrub Sink with Brush

    Continue working with the scrub brush which should get most of the residual staining from the seam around the drain.

    If you face deep scratches like this tutorial shows use a finishing sander and sand out the scratches.

    Start with 400-grit paper and see if that works. If not, continue with more aggressive grits, even to the point of  60-grit.

    DEEP SCRATCH REPAIR: Grooving the Sink

    To tackle deep scratches, fit an old rotary tool with an aluminum oxide bit to polish out the dark scratches. Try cleaning away the dark deposits within the scratches with denatured alcohol. Finally, fit the rotary tool with a diamond cutting wheel and cut a 1/8-in.-deep groove right on the dark marks. Work carefully, and it’ll remove the last of the scratches, but you’ll need to fill them in.

    DEEP SCRATCH REPAIR: Epoxy Fill the Repair Groove

    Mix a 2-part epoxy filler and work it into the grooves with a putty knife, leaving the filler a little bit higher than the sink surface. Once the filler is cured, go back to sanding—first with 80-grit paper to knock down the filler down flush with the surface, then working with progressively finer abrasives up to 200-grit to restore the sink finish.

    Sink Restored

    Once final sanding is complete your sink should look like new.Once you’ve gone to this effort to restore your solid-surface sink, maintain it by regularly cleaning it with an abrasive cleaner and pad. It’ll be much easier if you keep up with it rather than dealing with two (or more) years of build-up all at once, down the road.
