Quartz countertops are an increasingly popular choice for kitchen and bathroom surfaces due to their durability, aesthetics, and low maintenance. However, cleaning quartz properly is key to keeping it looking its best. Here is an in-depth look at the best practices for cleaning quartz countertops.
What is Quartz?
Quartz countertops, sometimes referred to as engineered stone, are made from ground natural quartz crystals combined with resins and pigments. This combination creates an incredibly hard, non-porous surface that resists scratches, stains, and heat.
While granite and marble are mined from quarries in large slabs, quartz slabs are manufactured in factories under carefully controlled conditions. This allows quartz to achieve a more uniform appearance than natural stone. The resins added give quartz increased flexural strength and resistance to cracks and chips.
Routine Cleaning of Quartz Countertops
- Use a mild soap and warm water. Dish soap or a stone cleaner without acidic or harsh ingredients are good options.
- Wipe the surface with a soft microfiber cloth after each use. This prevents buildup of dirt and grime that can become harder to remove.
- For food prep areas, disinfect the surface occasionally with a food-safe sanitizing spray. Diluted bleach can also be used.
- Be sure to thoroughly rinse and dry the surface after cleaning. Letting water pool can lead to calcium deposits.
What Not to Use on Quartz
- Avoid abrasive cleaners like powders, scouring pads, or steels wool. This can scratch and damage the surface.
- Don’t use highly acidic or alkaline cleaners, including bathroom cleaners, vinegar, ammonia, or lemon. Only use cleaners specifically formulated for natural stone.
- Never use harsh solvents like paint removers, turpentine, nail polish remover, etc. These can stain and etch the surface.
Deep Cleaning Quartz Countertops
Over time, quartz can develop hard water marks, oil buildup, and sticky messes that require more intensive cleaning. Here are some safe methods to deep clean quartz:
Baking Soda Paste
Make a paste of baking soda and water and apply to difficult stains. Let sit for 5-10 minutes before scrubbing lightly with a soft cloth or sponge. Rinse and dry thoroughly. The mild abrasive action of baking soda can lift stains without damaging the finish.
Heat Treatment
For stubborn organic stains like coffee, tea, or juice, use a hair dryer to heat the area for 30-60 seconds. The heat helps loosen the staining molecules so they can be wiped away more easily. Be sure to use a microfiber cloth and keep the dryer moving constantly.
Hydrogen Peroxide
As a mild bleach, hydrogen peroxide can lift some stubborn stains. Apply 3% solution, let sit briefly, and scrub gently before rinsing. Be sure to spot test first, as prolonged exposure can cause lightening of the quartz color.
Quartz Cleaning Sprays
Specialized stone cleaners, polishers, and sealers are widely available. Look for water-based formulas free of acids, alkalis, bleach or ammonia. Spray on, allow to sit per product directions, lightly scrub, and rinse thoroughly.
How to Sanitize Quartz Countertops
Disinfecting quartz surfaces is important in kitchens and bathrooms. Here are safe and effective options:
- Bleach solutions – 1 part regular bleach to 9 parts water. Apply, allow to sit 1-2 minutes, then wipe and rinse.
- Hydrogen peroxide – Same dilution as above. Peroxide can help remove stains as it disinfects.
- Quaternary ammonium – Look for this active ingredient in sanitizing wipes and sprays formulated for stone.
- Vinegar – Straight white vinegar will sanitize without the color removal of bleach solutions.
- 70% Isopropyl alcohol – Safe for occasional disinfecting. Avoid other alcohol types which can stain.
Be sure to thoroughly rinse and wipe dry after sanitizing to prevent residue buildup. Avoid using harsh disinfectants like chlorine concentrates routinely.
How to Remove Different Stains from Quartz
Accidents happen, but quartz’s non-porous nature means most stains can be removed with the right techniques:
Oil-based Stains
- First try diluted bleach, hydrogen peroxide, or baking soda paste. For tougher stains, apply a degreasing cleaner like Formula 409® or orange oil concentrate.
Ink Marks
- Apply rubbing alcohol or nail polish remover immediately before the ink dries. This may take repeated applications.
Hard Water Marks
- Use a vinegar and water solution or buffered cream cleanser. Agitate with a soft cloth or non-abrasive sponge.
Dried Cement or Mortar
- First scrape off any excess material with a plastic putty knife. Apply an acidic remover formulated for natural stone and scrub gently with a soft brush.
Etch Marks
- These whitish marks require refinishing and re-polishing of the damaged area. Consult a stone restoration professional for this repair work.
With care and prompt attention, most stains and marks can be removed from quartz surfaces. Be sure to thoroughly rinse and dry after applying any cleaning solutions.
Maintaining Quartz Countertops
- Use cutting boards and trivets for hot items from the oven or cooktop. Thermal shock can damage quartz.
- Clean up spills immediately to prevent stains setting in.
- Consider applying an impregnating sealer every 1-2 years for extra stain protection.
- Have professionally applied finishes re-applied every 3-5 years by a countertop specialist.
- Avoid using quartz polish or wax, as this can create a slippery, streaky buildup over time.
FAQs About Cleaning Quartz Surfaces
Can I use vinegar to clean quartz?
Yes, diluted white vinegar is generally safe for routine cleaning of quartz. Avoid prolonged exposure and do not use colored vinegars which can stain. Rinse thoroughly after using.
What is the best quartz countertop cleaner?
A pH-neutral stone cleaner without bleach or acidic ingredients is ideal. Dish soap and warm water can be used for everyday cleaning. Look for products specifically formulated for engineered stone.
How do you remove dried food from quartz?
Use a plastic scraper or putty knife to gently lift off dried food debris. Avoid metal scrapers or abrasive pads. For stuck-on messes, apply baking soda paste and let sit before scrubbing lightly with a soft cloth.
How do you get grease off a quartz countertop?
Degreasing cleaners like Formula 409® work well to dissolve greasy buildup. Apply with a soft cloth and let sit to penetrate before wiping clean. Avoid harsh chemical solvents.
Can you use Scrubbing Bubbles on quartz?
Most Scrubbing Bubbles cleaners contain bleach, which can damage and discolor quartz over time with repeated use. It’s best to stick to pH-neutral stone cleaners instead.
Conclusion
With proper daily and deep cleaning habits, quartz countertops can stay looking like new for many years. Using the right products and techniques keeps quartz clean and prevents etching or damage. Avoid abrasive cleaners or acids, work to promptly remove spills and stains, and disinfect surfaces regularly. With a little care, quartz countertops will provide durable beauty in kitchens and baths.
