What Are Corian Sinks Made Of?

Corian is a solid surface material that was first created by DuPont scientists back in 1967. It‘s still produced exclusively by DuPont today. The name "Corian" is actually a trademark.

It‘s composed of a proprietary blend of:

• Acrylic polymer (about 2/3 by weight) – This provides durability, stain resistance, and renewability
• Natural minerals and pigments (about 1/3) – These add strength, durability, and color

The most common mineral filler used is aluminum trihydrate derived from bauxite ore. It‘s the same mineral that gives ruby gemstones their red color!

Corian can be molded and shaped, so a Corian sink basin is constructed by taking a solid block of the material and sculpting out the sink shape. This creates a non-porous, seamless sink perfect for kitchens and baths.

One of the key advantages of Corian over materials like granite or ceramic is that small scratches can be sanded out. It can also be renewed by sanding down the surface if significant staining or damage occurs.

While not completely indestructible, Corian is highly resistant to stains, scratches, and heat under normal use when properly cared for. Let‘s look at what can damage it if not addressed.

What Typically Causes Stains in White Corian Sinks

Now you know white Corian sinks are tough, but not impervious to damage. Here are the top causes of stains and discoloration:

Dyes from Clothing, Towels or Hair

The acrylic polymer in Corian can absorb pigment molecules from fabric dyes, especially when wet. Red socks bleeding pink into the sink is a common example. Hair dye is another staining culprit.

Prevention is key, so avoid letting dyed textiles soak in a Corian sink basin. Promptly rinse any dye transfer.

Paints and Finishes

Oil-based paints and stains contain pigments and resins that can penetrate Corian if spilled. Using Corian as an impromptu paint mixing station is asking for stains!

Latex paint is lower risk, but can still stain if allowed to dry on the surface. Avoid paint-related accidents by covering your sink when renovating nearby.

Prolonged Bleach, Acid or Alkaline Exposure

While brief exposure to cleaners is fine, letting harsh chemicals soak into Corian can cause gradual discoloration or damage. This includes bleach, oven cleaners, and drain openers.

Acids from foods and beverages like vinegar, citrus juices, and wine can etch or discolor the sink if allowed to puddle and sit.

Heat Damage from Hot Pans, Objects

While able to withstand boiling water, excessive localized heat can scorch, blister or discolor a Corian sink. Placing smoking hot pans directly into the basin is risky.

Let pots and pans cool briefly before putting into your Corian sink to prevent thermal shock damage.

Abrasive Scrubbing, Aggressive Scraping

The solid, non-porous acrylic surface of Corian is highly scratch resistant but not scratch proof. Frequent harsh scrubbing or scouring with abrasives can damage the finish.

Avoid scratching by using soft cloths and sponges for cleaning. Never cut or chop directly on a Corian sink.

Hard Water Spots and Mineral Buildup

Like any sink material, Corian can develop mineral deposits from tap water over time. This dulls the glossy appearance.

Prevent buildup by drying your sink after use and occasionally cleaning with a hard water remover made for solid surfaces.

Accumulated Grease, Oil and Grime

Letting oils and greasy gunk from food accumulate will stain any sink over time. Promptly washing away cooking residues prevents staining.

Use an oil-cutting detergent like Dawn Powerwash to remove grime and grease before it penetrates.

Okay, now that you know what damages Corian, let‘s get into the nitty gritty of cleaning and care!

My 3-Step Process for Cleaning White Corian

Most sinks require frequent cleaning to look their best. Here is my easy 3-step method to clean and maintain a pristine white Corian sink:

Step 1: Rinse and Wipe Daily

After each use of your kitchen or bathroom sink, give it a quick rinse and wipe down with a soft microfiber cloth. This prevents the buildup of grime, oils, and soap scum that can stain over time.

It only takes seconds! Just rinse and wipe as part of your daily habit.

Step 2: Wash Weekly with Mild Detergent

About once per week, give your white Corian sink a deeper clean using a mild liquid dish soap or detergent and a soft sponge.

Gently wash the basin, sides, and drain area. Avoid abrasive scouring pads! Rinse thoroughly.

This will remove any oils, food residue or grime that daily wiping may have missed.

Step 3: Disinfect Monthly with Diluted Bleach

To kill bacteria and sanitize your sink, mix one part regular bleach to nine parts water. About once per month, wipe down your Corian sink with this diluted bleach solution using a soft cloth.

Let it contact the surface briefly before rinsing thoroughly. Avoid soaking the sink in bleach solution for prolonged periods.

And that‘s it – just rinse/wipe daily, wash weekly, and disinfect monthly! Now let‘s tackle removing stains…

My Go-To Methods for Removing Corian Sink Stains

Even with great daily care, stains can still happen. Don‘t panic! Here are my pro tips for stain removal:

For Dye Stains:

Make a paste of baking soda and water. Apply to stained area and let sit 5-10 minutes before scrubbing with a soft bristled brush. The abrasive baking soda will lift dye from the Corian. Rinse thoroughly.

For really stubborn dye stains, use some acetone nail polish remover on a cotton ball. Wipe stain, allowing acetone to penetrate briefly before rinsing. This breaks down and removes pigment.

For Paint and Finish Stains:

Carefully scrape off any dried bits with a plastic putty knife. Then apply rubbing alcohol to the stain and let sit before scrubbing with a soft brush. The alcohol dissolves paint binders.

For oil-based paints, use mineral spirits applied with a cotton ball and rinsed promptly. Avoid nail polish remover as it may dull the Corian finish.

For Heat Stains:

Mix a mild abrasive cleanser like Soft Scrub with a few drops of bleach. Apply to the stain for 2-3 minutes before scrubbing with a soft brush. The combination of abrasive and bleach removes scorched discoloration. Rinse thoroughly after.

For Hard Water Stains:

Spray vinegar or lemon juice directly on the stain. Allow to sit 5 minutes before scrubbing and rinsing. The acid dissolves mineral buildup.

For really tough hard water stains, apply a commercial lime scale remover made for solid surface materials. Check manufacturer instructions.

For Grease and Oil Stains:

First blot excess oil immediately after a spill to prevent sinking in. Then make a baking soda paste and scrub into the stain before rinsing. The baking soda grabs and lifts grease.

You can also use an oil-cutting detergent like Dawn Powerwash spray to break down oils. Let it soak briefly before wiping clean with a soft cloth or sponge.

Okay, those are my best stain removal secrets revealed! Now let‘s get into the daily and weekly care that keeps your sink pristine…

Daily and Weekly Care Tips for Corian Sink Maintenance

We‘ve covered cleaning – now let‘s get into the key things you should do daily and weekly to maintain your sink:

Daily Care Tips

• Wipe down basin, sides & drain area after each use
• Blot spills immediately to prevent staining
• Avoid exposing sink empty sink to extreme heat
• Don‘t let fruit juices, vinegars or wines sit – rinse promptly!

Weekly Care Tips

• Wash entire sink with mild detergent and soft sponge/cloth
• Use a hard water removing cleaner weekly if you have hard water
• Disinfect monthly with diluted bleach solution
• Consider using a basin rack or rubber mat to protect sink bottom

That‘s all it takes to keep your sink looking like new day after day! Now let‘s talk about when to reseal…

Resealing Your Sink Every 6 Months is Recommended

While not strictly required, I recommend applying a penetrating sealer to your Corian sink every 6 months.

Sealing fills in microscopic pores and creates a protective barrier that repels stains. It also makes the sink surface smoother so grime doesn‘t cling as easily.

Look for sealers specifically made for solid surface materials like Corian. I recommend using the DuPont StoneTech Professional BulletProof Sealer – it works great!

After cleaning your sink, apply 2-3 thin coats according to the product directions, buffing in between each coat. Let the sealer cure fully before use.

And that covers the key points for care, cleaning and maintenance! Now let‘s get into some common questions about Corian sinks:

Answers to Your Frequently Asked Corian Sink Questions

I get a lot of questions from clients about Corian sinks, so here are some of the common ones along with my answers:

Are coffee and tea stains permanent in Corian sinks?

Nope! Corian is highly stain resistant. As long as you promptly rinse away coffee, tea, juice and other drinks after use, they won‘t stain. For dried on stains, use baking soda and water to remove.

Can I pour boiling water directly into my Corian sink?

It‘s best not to dump a full stockpot of boiling water into an empty sink as the sudden temperature change can damage any material. Run some hot tap water first to preheat the basin before adding boiling water.

Is it okay to cut food directly on a Corian sink surface?

I don‘t recommend it – Corian is durable, but not immune to knives and sharp objects. Always use a cutting board to protect your sink‘s finish.

Can I use Corian sinks in a rental property?

Definitely! Corian is an ideal material for rental units since it‘s durable and easy to renew by sanding out damage. Just expect to replace or resurface it every 5-10 years with heavy use.

How long will a Corian sink really last?

With proper care and maintenance, a Corian sink should last 10-15 years before needing resurfaced. I‘ve seen Corian in perfect shape even longer when well cared for.
