How To Clean Stubborn Stains On Quartz Countertops

Quartz countertops are popular in many modern homes due to their durability, aesthetic appeal, and low maintenance. However, like any surface, quartz can get stained over time with spills and daily use. The good news is that quartz is non-porous, making it resistant to stains. With the proper cleaning methods, you can often remove stains from quartz and restore its original beauty. This comprehensive guide will provide tips on how to clean even stubborn stains on quartz countertops.

What Causes Stains on Quartz Countertops?

Quartz is impressively stain-resistant, but not completely stain-proof. Certain materials can leave behind stubborn marks if left on the surface. Here are some common causes of stains on quartz:

Food and Beverages

Foods and drinks that are strongly pigmented or acidic can seep into microscopic pits and pores in the surface. Examples include:

  • Wine, coffee, tea, juice – These can leave behind colored stains.
  • Tomato sauce, mustard, curry – Contain staining pigments.
  • Citrus fruits – The acidity can etch the surface.
  • Oil and grease – Can leave oily residue and buildup.

Household Products

Cleaning agents, chemicals, and cosmetics can react with the quartz and alter its appearance:

  • Bleach, oven cleaners, drain cleaners.
  • Nail polish remover, perfume, makeup.
  • Metal polish or jewelry cleaner.
  • Dyes or pigments from potting soil, arts and crafts.

Hard Water Buildup

Mineral deposits from tap water can leave cloudy streaks and spots on quartz when left to accumulate.

Other Causes

  • Melted plastic or rubber.
  • Heat damage from hot pans or objects.
  • Scrapes and scratches from rough handling.
  • Discoloration from UV exposure.

How to Remove Common Stains from Quartz

The secret to cleaning quartz lies in using the gentlest method that effectively lifts the stain. Start with milder techniques and gradually work up to stronger methods for stubborn marks.

Step 1: Soft Cloth and Water

For light stains that have not set in, simply use a soft damp cloth or paper towel to wipe the area gently. The moisture can lift many fresh spills before they have a chance to soak in.

Avoid abrasive scrubbing, which may spread the stain further. Wipe in a circular motion and rinse the cloth as needed.

Step 2: Mild Soap and Water

If water alone does not do the trick, add a couple drops of mild dish soap. Use a soft sponge or cloth to clean the stain gently with the soapy water.

Rinse thoroughly afterwards, then dry with a soft towel. The soap helps lift oil-based spills. Take care not to use harsh detergents.

Step 3: Baking Soda Paste

For more stubborn stains, make a paste of baking soda and water. Apply the paste directly on the stain and let it sit for 5-10 minutes. Baking soda is a mild abrasive that can help lift surface discoloration without damaging the quartz.

Use a soft brush or sponge to gently scrub the paste. Rinse and dry the area thoroughly afterwards. Avoid scrubbing too vigorously.

Step 4: Hydrogen Peroxide

As a bleaching agent, hydrogen peroxide can help remove some stubborn food and beverage stains, like coffee and tea. Use a 3% solution. Apply a small amount directly on the stain and let sit for 10 minutes.

Use a soft cloth to blot the hydrogen peroxide and lift the stain. Rinse thoroughly. Repeat if needed for tough stains. This generally lightens stains without damaging the surface.

Step 5: Acetone

For dried on oil stains or residues, try using a small amount of acetone on a soft cloth. Wipe the stain gently. Take care not to spread the spill.

Acetone can remove stubborn grease but can also damage quartz if used harshly. Use sparingly and rinse thoroughly afterwards. Wear gloves when handling. Work in a well-ventilated area.

Step 6: Quartz Cleaner

Specialized quartz cleaning solutions are formulated to remove all kinds of stains without harming quartz surfaces. Look for non-acidic cleaners made specifically for stone and quartz.

Apply a small amount directly on the stain as directed. Gently scrub with a soft brush or sponge. Avoid abrasive pads. Rinse thoroughly afterwards.

Step 7: Magic Eraser

Magic erasers work well for surface stains on quartz. Their melamine foam lifts pigments and residues without scratching. Dampen the eraser and rub gently over the stain. Apply light pressure and avoid excessive scrubbing.

This works well for stains from food, drinks, and dyes that are not etched into the surface. Rinse and dry thoroughly afterwards.

Tips for Preventing Stains on Quartz

Prevention is key for keeping quartz counters in pristine condition. Follow these tips to minimize stains:

  • Wipe up spills immediately before they have a chance to set in. A quick wipe makes cleaning much easier.
  • Always use cutting boards, trivets and mats when prepping food or placing hot items on quartz. This prevents direct contact that can stain or damage the surface.
  • Clean counters frequently with a mild soap and water to prevent buildup of grime.
  • Avoid exposing quartz to strong chemicals like paint removers, oven cleaners, etc. Always keep such products away from the counters.
  • Rinse quartz surfaces thoroughly after cleaning to remove any residue.
  • Reseal quartz annually with a penetrating sealer to reinforce stain protection.
  • Check manufacturer care instructions and follow any specific maintenance guidelines.
