Can You Use Rubbing Alcohol to Clean Quartz Countertops?

Quartz countertops are an increasingly popular choice for kitchen and bathroom remodeling projects. Made from engineered stone, quartz counters are praised for their durability, low maintenance, and stylish appearance. But like any surface, quartz countertops do require occasional cleaning to keep them looking their best. This raises the question – can you use rubbing alcohol to clean quartz countertops?

What is Quartz?

Before diving into cleaning methods, it helps to understand exactly what quartz countertops are made of. Quartz is an engineered composite material that consists primarily of quartz mineral rocks that have been pulverized into a fine powder. This quartz powder comprises roughly 90% of the material’s weight.

The remaining 10% is composed of polyester resins and pigments that bind the quartz particles together and give the countertops their color and pattern. Additional compounds like recycled glass or mirrors may also be added for sparkle.

The mixture is compacted under intense pressure and vibration, then hardened into slabs. Quartz slabs are extremely dense and non-porous, making them stain, scratch, and heat resistant compared to other natural stone counters.

While often referred to simply as “quartz”, these engineered slabs are not the same thing as a natural quartzite stone surface. Knowing the composition helps inform the best cleaning practices.

Is Rubbing Alcohol Safe for Cleaning Quartz?

Rubbing alcohol refers to either isopropyl alcohol (IPA) or ethyl alcohol diluted with water to create an antiseptic solution. It typically contains around 70% alcohol mixed with 30% water.

Rubbing alcohol is a relatively gentle disinfectant that can kill many common germs, viruses, and bacteria. It evaporates quickly without leaving streaks or sticky residues. These characteristics make it a convenient cleaner for many household surfaces.

But is it safe to use on quartz counters? According to most manufacturers, yes – rubbing alcohol is considered a quartz-safe cleaner when used properly. The key things to keep in mind are:

  • Use a diluted solution. 70% rubbing alcohol is typically recommended for cleaning quartz. Higher concentrations may damage some resin-based quartz.
  • Spot test first. Dab a bit of diluted rubbing alcohol on an inconspicuous area before widespread use to check for any adverse effects.
  • Avoid prolonged exposure. While brief contact is ok, you don’t want to soak the countertops in alcohol or leave it sitting for extended periods, as this could damage the resin binders.
  • Rinse after use. Make sure to wipe the surface with water after cleaning with rubbing alcohol to remove any residue.

With proper precautions, using rubbing alcohol to disinfect and clean quartz countertops poses little risk of harm. Just be careful not to oversaturate the surface and promptly rinse after using.

How to Clean Quartz Countertops with Rubbing Alcohol

Follow these steps for safely using rubbing alcohol as a quartz countertop cleaner:

Supplies Needed

  • 70% isopropyl rubbing alcohol
  • Soft, non-abrasive cloth or sponge
  • Water
  • Optional: Microfiber towel for drying

Step 1 – Dust and Dry the Surface

Before introducing any liquids, wipe the countertop with a dry cloth to remove loose dirt and debris. Make sure the surface is completely dry before applying the rubbing alcohol.

Step 2 – Mix the Rubbing Alcohol Solution

Pour a small amount of 70% isopropyl alcohol into a spray bottle. Avoid using higher concentrations like 90% as these are more likely to damage the resin.

You can dilute the rubbing alcohol further by adding an equal part water if desired. But 50-70% alcohol content is typically recommended.

Step 3 – Spot Test the Solution

Lightly spray or wipe a small amount of the rubbing alcohol solution onto an inconspicuous area of the quartz. Check for any discoloration or damage to the surface after 1-2 minutes. If no adverse effects are noticed, proceed to step 4.

Step 4 – Apply the Rubbing Alcohol

Spray or wipe the diluted alcohol onto the soiled areas of the countertop you wish to clean. Try to avoid saturating the entire surface – use only as needed for targeted cleaning.

Let the rubbing alcohol solution sit for 30-60 seconds so it can effectively kill germs and dissolve grease and grime.

Step 5 – Wipe and Rinse

After letting it briefly sit, wipe down the quartz with a clean damp cloth or sponge to remove any residue. Follow with a rinse of plain water over the areas where alcohol was used.

Make sure no alcohol remains on the surface before moving on. Overexposure can damage the resin sealants in quartz over time.

Step 6 – Dry the Surface

Finally, go over the counters with a clean microfiber cloth or towel to absorb any remaining moisture. Getting the surface completely dry helps prevent water spots or buildup of leftover cleaning product.

And that’s it! With this simple rubbing alcohol cleaning method, you can safely disinfect and remove many common messes from quartz countertops without worry. Just be careful not to oversaturate the surface, rinse thoroughly after cleaning, and dry well for best results.

What Types of Dirt and Stains Can Rubbing Alcohol Remove from Quartz?

When used properly, here are some of the many types of grime and messes that can be cleaned off quartz counters with rubbing alcohol:

  • Bacteria – Rubbing alcohol is an antiseptic capable of killing E. coli, Salmonella, Streptococcus, and many other bacteria.
  • Viruses – Effective against rhinovirus, influenza, norovirus, and coronaviruses like SARS-CoV-2.
  • Grease and Oil – Breaks down most types of grease and cooking oils easily.
  • Soap Scum – Removes built-up residues from hand soaps and dish soaps.
  • Hard Water Spots – These mineral deposits come off easily with rubbing alcohol.
  • Dye Transfer – Lifts away fabric dye, marker, and pen stains.
  • Cosmetics – Gets rid of smeared makeup and beauty products.
  • Food Stains – Especially effective for wine, coffee, tea, juice, and other drink spills.
  • Fingerprints – Eliminates oily fingerprint smudges effortlessly.

Just avoid using rubbing alcohol on quartz counters if the stain originates from strong chemicals like paint removers, oven cleaners, drain openers, etc. Test other harsh cleaners on a small spot first to ensure compatibility with the resin sealant.

Alternative Alcohol-Based Quartz Cleaners

While 70% isopropyl alcohol is readily available in any pharmacy or general store, some people prefer not to use rubbing alcohol on their countertops. In that case, a few alcohol-based alternatives can also clean and disinfect quartz effectively:


Most vodka contains 40% alcohol content, making it concentrated enough to sanitize countertops and remove many stains without leaving a medicinal aroma like rubbing alcohol. Any inexpensive unflavored vodka variety will work.

Denatured Alcohol

Sometimes called methylated spirits, this highly-concentrated ethanol formula will cut through residue but may need dilution with water to avoid damaging quartz resins.

Grain Alcohol

Another highly-potent solution, grain alcohol contains 95% alcohol content derived from fermented grains. Use extreme care and dilute substantially if attempting to substitute grain alcohol for rubbing alcohol on quartz.

Glass Cleaners

Many commercial glass cleaners rely on alcohol bases like ammonia to cut through dirt. Check that these products are approved for use on quartz counters first.

Hydrogen Peroxide

While not an alcohol itself, hydrogen peroxide is another antiseptic liquid that can often safely replace rubbing alcohol for quartz cleaning. Look for 3% solutions.

Be sure to spot test any alternative cleaning agents before widespread use on quartz counters to ensure compatibility. Follow all safety precautions when using alcohol-based cleaners.

Best Practices For Cleaning Quartz Countertops

While effective in many cases, rubbing alcohol isn’t necessary during routine quartz cleaning. Follow these best practices for maintaining sparkling quartz counters:

  • For daily cleaning, just use a soft sponge or cloth with warm water and a small amount of mild soap as needed. Avoid abrasive scrubbers.
  • For a deeper but gentle clean, mix together an equal parts solution of clear ammonia and warm water. Make sure the room is well ventilated.
  • Disinfect the surface periodically by wiping it down with a 50/50 white vinegar and water mixture. Rinse well.
  • For stuck-on dried spills or stains, apply a quartz-safe cleaner (like the alcohol options above) to a cloth and let it sit directly on the soiled area for 1-2 minutes before wiping.
  • Avoid using highly acidic cleaners like lemon juice, bleach, alkaline drain cleaners, etc. which can etch and damage quartz over time.
  • Reseal the countertops every 1-2 years with a quartz-specific sealer to enhance stain resistance.

By following the manufacturer’s care guidelines, quartz countertops are quite forgiving and low maintenance compared to other natural stone surfaces. But be sure to rinse completely after any cleaning agent to prevent buildup in the pores of this engineered composite material. With regular upkeep, quartz can stay looking like new for decades.
