Quartz countertops are a popular choice for kitchens and bathrooms due to their durability, aesthetics, and low maintenance. However, like any countertop material, quartz can become stained over time with use. The good news is that quartz is non-porous, making stains relatively easy to remove with the proper cleaning methods. Here is an in-depth guide on how to fix stains on quartz countertops.

Supplies Needed for Stain Removal

Before tackling stain removal, gather the proper supplies:

• Mild dish soap or delicate stone soap
• Soft cloths and sponges
• Clean water
• 50/50 vinegar and water solution
• Baking soda
• Hydrogen peroxide
• Non-abrasive scrubbing pad or soft-bristle brush
• Poultice powder (pre-mixed or homemade blend)
• Painter’s tape
• Eye and skin protection

Assessing the Stain

Not all stains on quartz countertops are created equal. To properly remove them, you must first identify the type of stain.

Types of Stains on Quartz

There are five common categories of stains:

Organic Stains

Caused by food, beverages, plant matter, mildew, mold, or bacteria. Examples are coffee, tea, wine, fruit juice, and vegetables.

Oily Stains

Caused by vegetable oils, grease, cosmetics, lotions, butter, etc.

Metal Stains

Caused by reactive metals like copper and iron. Prolonged contact can etch into the surface.

Ink Stains

From markers, pens, permanent ink, etc. These can be challenging to remove entirely.

Water Stains

Mineral deposits and hard water stains. These appear after evaporation of standing water.

Determining Stain Age

It’s also important to consider how long the stain has set:

• New stains are within 24 hours old.
• Intermediate stains are 1-7 days old.
• Old stains exceed 1 week old.

New and intermediate stains are easier to remove than old, stubborn stains.

Performing a Spot Test

Always do a spot test of any cleaning solution on an inconspicuous area of the quartz. This will indicate if the solution is too harsh and could potentially damage the finish.

Cleaning Solutions for Stain Removal

With the supplies gathered and stain assessed, you can choose the best cleaning solutions for removing it:

For New and Intermediate Stains

• Dish soap – dissolve in warm water and apply to stain with soft cloth or sponge. Rinse thoroughly.
• Baking soda paste – mix with just enough water to form spreadable paste. Apply and let sit for 5 minutes before scrubbing and rinsing.
• Vinegar solution – moisten stained area with 50/50 vinegar and warm water. Allow to sit briefly before wiping and rinsing.
• Hydrogen peroxide – apply small amount directly on stain and allow to bubble. Rinse thoroughly once bubbling stops.

For Old, Stubborn Stains

• Poultice – cover stain completely with poultice paste. Allow to set according to directions, then rinse. May require repeating.
• Bleach or ammonia – use as absolute last resort and carefully spot test first. Apply sparingly to stain and rinse immediately.

Step-by-Step Stain Removal Process

Follow these steps closely for best results removing stains from quartz:

1. Prepare the Countertop Surface

• Clear countertop of any dishes, appliances, food, etc.
• Tape down paper towels or plastic wrap around the stain to prevent runoff to other areas.
• Ensure you have adequate ventilation.
• Put on gloves and eye protection.

2. Try First Cleaning Attempt

• Start with the gentlest option like dish soap or DIY poultice based on stain type and age.
• Follow directions accordingly. Allow time for solution to work before rinsing.
• Scrub gently with soft cloth, sponge or non-abrasive pad. No rough scouring.
• Completely rinse area with clean water, wiping excess moisture with dry towel.

3. Check Results

• Allow countertop to fully dry.
• Inspect area under adequate lighting to determine if stain persists.
