How to Remove Stains from Quartz Kitchen Countertops

Quartz countertops are a popular choice for kitchens due to their durability, stylish appearance, and low maintenance. However, like any surface, quartz can get stained from spills and daily wear and tear. The good news is that quartz is non-porous, making stains easier to remove than on porous natural stone. Here is a comprehensive guide on how to remove stains from quartz kitchen countertops.

What Causes Stains on Quartz Countertops?

Quartz is resistant to scratches, heat, and most household stains. However, some substances can discolor or stain the surface over time. Common causes of stains include:

  • Oil-based products like cooking oils, grease, and lotions
  • Foods and beverages with pigments like tomato sauce, coffee, and wine
  • Hard water spots and mineral deposits
  • Mold, mildew, and bacteria buildup
  • Harsh cleaners and chemicals that eat away the sealer

Proper daily maintenance and prompt cleaning of spills can prevent most stains. But accidents happen, so it helps to know how to remove existing stains from quartz.

Supplies Needed for Removing Quartz Stains

Having the right cleaning supplies ready will let you tackle stains quickly. Here are some must-have items:

  • Mild liquid dish soap
  • White vinegar or ammonia-based cleaner
  • Baking soda
  • Soft damp microfiber cloth
  • Non-abrasive scrub pad or sponge
  • Small brush or toothbrush for grout
  • Quartz polish or sealant (optional)

Avoid using any abrasive pads, scouring powders, or strong chemicals like bleach that could scratch or dull the quartz. Test any new cleaners in an inconspicuous spot first.

Step-by-Step Guide to Removing Tough Stains

Follow these methods to clean various stubborn stains from quartz countertops:

For Dried Food, Grease, and Oil Stains

  1. Scrape off any chunks of dried food gently with a plastic scraper or card. Don’t use anything sharp or metal that could scratch the surface.
  2. Mix a paste of baking soda and water and spread over the stain.
  3. Let sit for 15-30 minutes. This draws out oil and grease stains.
  4. Scrub with a damp microfiber cloth or soft bristle brush in circular motions.
  5. Rinse clean and wipe dry with a soft towel.

For Tomato Sauce, Beetroot, and Other Red Pigment Stains

  1. Wipe the stain with undiluted white vinegar using a cloth. The acetic acid in vinegar breaks down pigment stains.
  2. Let sit for 5 minutes so the vinegar can work.
  3. Scrub gently with a damp microfiber cloth.
  4. Rinse with clean water and dry.
  5. For stubborn stains, make a baking soda paste after the vinegar and scrub.

For Coffee, Tea, Wine, and Fruit Juice Stains

  1. Mix equal parts baking soda and hydrogen peroxide into a spreadable paste.
  2. Apply the paste on the stain and let sit for 20-30 minutes. This bubbly mixture lifts both pigments and tannin stains.
  3. Wipe clean with a damp microfiber cloth.
  4. Follow with a clean water rinse and buff dry with a soft towel.

For Mold, Mildew, and Bacteria Stains

  1. Mix one part chlorine bleach to four parts water for a safe disinfecting solution.
  2. Apply to stained areas and let sit briefly.
  3. Scrub with a soft bristle brush and rinse thoroughly.
  4. Allow to dry fully before using again. Bleach can dull quartz over time, so use sparingly.

For Hard Water Stains and Mineral Buildup

  1. Make a paste of baking soda and water and apply to the stains.
  2. Let sit for a few minutes before scrubbing with a soft bristle brush. The baking soda is a gentle abrasive.
  3. Spray leftover paste with white vinegar and let fizz for 2-3 minutes. Vinegar helps dissolve mineral deposits.
  4. Rinse clean with water and dry completely.
  5. For tough hard water stains, use a quartz-safe limescale remover.

For Stains from Harsh Cleaners or Chemicals

  1. Wet the stained areas of the countertop.
  2. Sprinkle some baking soda and gently rub it in using a damp microfiber cloth.
  3. Let sit for 10 minutes before rinsing clean. The baking soda polish helps remove acid-based stains.
  4. Follow up by buffing the areas with a quartz sealant using gentle circles. This seals and protects the surface.

Tips for Preventing Future Stains

Once you get your quartz counters stain-free, follow these tips to keep them that way:

  • Wipe up spills immediately to prevent setting.
  • Use coasters under glasses and bottles.
  • Avoid abrasive pads or powders that could scratch.
  • Clean regularly with a mild PH-neutral soap.
  • Reapply quartz sealant every 1-2 years per manufacturer instructions.
  • Don’t use countertop as a cutting board to avoid nicks and cuts.
  • Keep cooking oils and pigment-rich foods away from counter edges.

Can All Stains Be Removed from Quartz?

In most cases, stains can be removed from quartz surfaces with the proper cleaning methods and a bit of elbow grease. But some very stubborn stains may permanently discolor if left too long. Avoid harsh chemicals like paint removers, oven cleaners, etc that can quickly damage quartz. For super tenacious stains that don’t respond to home remedies, contact a professional stone restoration company.

Proper maintenance and prompt cleaning help ensure your quartz countertops stay looking like new for years. Follow these stain removal techniques and prevention tips to keep your kitchen counters gorgeous. With a little care, quartz provides a durable, low-maintenance surface that stays spotless.
