How to Keep Black Quartz Countertops Shiny

Black quartz countertops can add a modern, sophisticated look to any kitchen or bathroom. However, like all countertop materials, quartz requires regular cleaning and maintenance to keep it looking its best. Here are some tips on how to keep black quartz countertops looking shiny and new.

Clean Regularly

  • Wipe down quartz countertops daily with a soft, damp microfiber cloth to remove dust, crumbs, and spills. This regular cleaning helps prevent buildup that can dull the surface over time.
  • For a deeper clean, use a nonabrasive quartz cleaner and a soft cloth or sponge once a week. Avoid harsh cleaners like bleach or abrasive scrubbing pads which can damage the finish.
  • Thoroughly rinse and dry the surface after cleaning. Leaving any cleaning solution behind can cause streaks.

Remove Stains Properly

  • For dried spills or stains, try a gentle quartz cleaner first. Spray it on the area, allow it to sit for a few minutes, then wipe clean with a soft cloth.
  • For stubborn stains, make a paste of baking soda and water. Gently rub the paste on the stain using a soft cloth or plastic scraper. Rinse thoroughly.
  • Avoid using abrasive cleaners or scrubbers which can permanently scratch the quartz. Always check cleaner labels to ensure they are safe for use on quartz.

Reseal as Needed

  • Quartz countertops are nonporous so liquids don’t penetrate the surface, but sealing is still recommended every 1-2 years. This adds an extra layer of protection against stains.
  • Use a sealant specifically formulated for quartz. Apply a thin layer across the entire countertop following label directions. Buff off any excess.
  • Resealing annually helps maintain the glossy just-installed sheen. It also makes regular cleaning easier.

Prevent Damages

  • Use cutting boards, trivets and heat resistant pads under hot pans and appliances. Direct high heat can damage quartz.
  • Clean up any spills immediately to prevent possible stains, especially oils, wines and acidic liquids like citrus juice.
  • Avoid sitting or placing heavy loads on countertop edges which can cause stress cracks or chips over time.

Professional Care

  • For periodic deep cleaning and resealing, consider hiring a professional quartz countertop cleaning service. They have specialized tools and products.
  • Professionals can also polish out minor scratches and etching in quartz. Refinishing restores the smooth surface shine.
  • Ask about warranties – some companies guarantee their countertop cleaning and refinishing services for a certain time period.

DIY Polishing

  • Minor scratches can often be buffed out at home using a handheld quartz polishing kit. Choose a kit with a 3000+ grit diamond polishing pad.
  • Work in small sections, keeping the pad flat against the surface. Rinse pads often to remove residue. Several passes may be needed.
  • Be cautious using polishing kits near edges or seams which are more prone to chipping. Consider hiring a pro for these areas.

With proper care and maintenance, black quartz countertops will maintain their beautiful polished look and last for many years. Consistent cleaning, prompt stain removal, and resealing are the keys to keeping quartz shiny and lustrous. Taking steps to prevent damage will also preserve the smooth surface shine.
