How to Whiten Quartz Countertops

Quartz countertops are a popular choice for many homeowners due to their durability, aesthetics, and low maintenance. However, over time quartz can become stained or yellowed, making your countertops appear dingy. If your quartz countertops have lost their original bright white luster, don’t worry! With the right products and techniques, you can restore them to their former glory.

What Causes Quartz Countertops to Become Stained?

There are a few common culprits that can cause quartz countertops to become stained or discolored:

  • Spilled foods and beverages – Things like wine, coffee, and tomato sauce can stain if left to sit.
  • Grease and oil – Cooking oils can leave behind a yellowish residue.
  • Hard water deposits – Minerals in hard water can leave dull, whitish spots.
  • Sun exposure – UV rays can cause quartz to yellow over time.
  • Improper cleaning – Harsh cleaners and abrasive pads can damage the surface.

How to Whiten Quartz Countertops

Step 1: Clear counters and rinse

Before whitening, thoroughly clear all items from the countertops. Give the counters a thorough rinsing to remove any debris or loose dirt. This allows you to see the stain and focus on problem areas.

Step 2: Mix baking soda and water paste

Make a paste by mixing equal parts baking soda and water. Baking soda is a gentle abrasive that can help lift stains without damaging the quartz. Mix to form a spreadable paste.

Step 3: Apply paste to stained areas

Use a soft cloth or sponge to rub the baking soda paste onto stained areas. Apply a thick layer of paste and let it sit for 5-10 minutes. Re-apply as needed. Avoid scrubbing harshly.

Step 4: Rinse and dry completely

Thoroughly rinse countertops with clean water to remove all paste. Make sure to rinse any crevices. Wipe the countertops completely dry with a soft cloth.

Step 5: Use hydrogen peroxide

For stubborn stains, apply hydrogen peroxide directly to the stain. Let it bubble for 2-3 minutes, then wipe away. Rinse again. Hydrogen peroxide can help lift discoloration without bleaching.

Step 6: Clean with non-abrasive quartz cleaner

Use a specially formulated non-abrasive quartz cleaner and a soft cloth to remove residual stains. Clean the entire surface to restore even shine and luster.

Step 7: Re-seal and polish

Apply a quartz countertop sealer per manufacturer instructions. This adds protection. Finish by polishing with a quartz polish to maximize shine.
