How to Clean Unsealed Quartz Countertops

Quartz countertops are durable and low-maintenance, but they still require regular cleaning to keep them looking their best. Unsealed quartz is more porous than sealed quartz, so it’s important to clean it properly to prevent stains. Here is a step-by-step guide on how to clean unsealed quartz countertops.

What You’ll Need

  • Microfiber cloths
  • Soft scrub brush
  • Mild dish soap
  • Water
  • 50/50 vinegar and water solution
  • Quartz cleaner or stone cleaner

Routine Cleaning

For day-to-day cleaning, follow these steps:

1. Remove any debris

Wipe down the countertop with a dry microfiber cloth to remove any crumbs or spills sitting on the surface. This prevents them from getting smeared around in the next steps.

2. Mix dish soap and water

In a spray bottle, mix a couple drops of mild dish soap with warm water. Avoid using harsh cleaners or anything acidic.

3. Spray and wipe

Spritz the cleaner onto the countertop and wipe down the surface with a damp microfiber cloth. Scrub gently with a soft brush if needed.

4. Rinse

Wipe again with a clean, damp cloth to rinse away all the soap.

5. Dry

Finish by wiping the countertop down with a dry microfiber towel. This prevents water spots or mineral deposits from building up.

Deep Cleaning

For a more thorough cleaning, do a deep clean treatment:

1. Clean as normal

Start by doing steps 1-4 of the routine cleaning. This removes surface debris and dirt.

2. Disinfect with vinegar

Spray the countertop with a 50/50 mixture of water and vinegar. This helps kill bacteria and gives a boost of cleaning power.

3. Scrub and rinse

Scrub the vinegar solution over the surface with a soft brush, then rinse thoroughly with clean water.

4. Quartz cleaner treatment

Apply a quartz-specific cleaner or stone cleaner over the entire countertop. Rub it over the surface with a damp microfiber cloth. This helps remove stubborn stains from grease, food, and more.

5. Rinse and dry

Rinse thoroughly with clean water and wipe dry with a cloth. This completes the deep clean.

Stain Removal

For stubborn spots and stains, use these techniques:

  • Dried food stains – Let a damp cloth soaked in the dish soap cleaner sit on the stain for 5 minutes, then scrub gently.
  • Grease/oil stains – Spray with an all-purpose stone cleaner and let sit for 5-10 minutes. Scrub then rinse.
  • Water spots – Dab white vinegar on the spots and wipe immediately.
  • Other stains – Make a baking soda paste with water, apply to the stain for 5-10 minutes then scrub and rinse.

Maintenance Tips

  • Use coasters under cups or containers to prevent etching.
  • Seal any cracks or seam lines to prevent moisture damage.
  • Avoid exposing the countertop to strong chemicals like paint removers or oven cleaners.
  • Re-seal the countertop every 1-2 years for added protection.
  • Clean spills promptly to prevent stains setting in.
