Black quartz countertops are a popular choice for modern kitchens and bathrooms due to their sleek, stylish appearance and durability. However, like all countertop materials, they require regular cleaning to keep them looking their best. Here is a comprehensive guide on how to clean black quartz countertops.
What is Black Quartz?
Black quartz countertops, also sometimes called black quartzite, are made from crushed quartz aggregated with resin binders. The quartz pieces give the countertop its hardness and durability, while the black pigment provides its dark color.
Black quartz is non-porous, making it resistant to stains and easier to keep clean compared to natural stone countertops. It has a glossy, mirror-like surface when polished, giving kitchens and bathrooms a modern, sophisticated look.
Routine Cleaning of Black Quartz Countertops
Daily cleaning is simple for black quartz countertops. Here are tips for keeping them looking pristine day-to-day:
- Wipe up spills immediately using a soft cloth or paper towel. Don’t let liquids sit.
- Use a mild soap and warm water. Apply it to the cloth/towel instead of directly on the countertop.
- Rinse thoroughly after cleaning and dry with a soft cloth to prevent water spots.
- For dried messes, use a non-abrasive cleaner formulated for stone surfaces.
- Disinfect periodically with a cleaner containing bleach.
- Avoid harsh cleansers, alkaline or acidic cleaners, abrasive pads/sponges, and scrubbing.
What Not to Use When Cleaning Black Quartz
It’s important to avoid certain cleaners and techniques when cleaning and maintaining black quartz:
- No acidic cleaners like vinegar, lemon, etc. These can etch the surface.
- No abrasive pads, scrubbing brushes, or powders. They will scratch the glossy finish.
- No harsh alkaline cleaners like oven cleaner. These can damage the resin binders.
- No oil-based soaps. They will build up and create streaks.
- No ammonia-based cleaners. They can discolor quartz over time.
Deep Cleaning Black Quartz Countertops
For a more thorough periodic cleaning, use these steps:
Step 1 – Remove everything from the countertop
Clear all accessories, appliances, etc. so you can access the entire surface.
Step 2 – Clean with a stone-safe cleaner
Apply a non-abrasive stone cleaner to the quartz. Let it sit for 5-10 minutes before scrubbing lightly with a soft cloth or brush. This will help lift oil and grime from the surface.
Step 3 – Rinse and dry the surface
Rinse thoroughly with clean water to remove all cleaner residue. Wipe dry with a soft, lint-free cloth.
Step 4 – Disinfect the surface
Use a disinfectant designed for stone to sanitize the countertop. Common options are hydrogen peroxide, rubbing alcohol, and bleach solutions.
Step 5 – Reseal if needed
Quartz countertops are non-porous so sealing isn’t required. But it can help strengthen protection from stains. Use a sealer made for quartz every 1-2 years.
How to Remove Common Stains from Black Quartz
Black quartz is less prone to staining than lighter colored natural stone. But some stubborn stains can still occur. Here are tips for removing them:
- Oil/grease stains – Use baking soda and water paste. Let sit briefly before scrubbing and rinsing.
- Dried food stains – Soak with wet cloth then use a plastic scraper to gently lift off. Rinse.
- Wine, coffee, juice stains – Clean with hydrogen peroxide and rinse thoroughly.
- Hard water spots – Use a little white vinegar and rinse completely.
- Marker, paint, dye stains – Try gently wiping with rubbing alcohol. Rinse thoroughly after.
- Mold/mildew stains – Use hydrogen peroxide or chlorine bleach cleaner. Don’t mix bleach and ammonia.
If stains persist, contact a professional stone restoration company. Harsh scrubbing can damage the quartz.
Maintaining the Finish on Black Quartz Countertops
Black quartz has a durable, glossy polished finish. But proper care is needed to maintain its flawless look over years of use. Here are tips:
- Use coasters under glasses and placemats under dishes.
- Don’t cut directly on the countertop surface. Always use a cutting board.
- Avoid dragging cookware or appliances across the quartz. Lift instead.
- Blot up spills immediately – don’t let liquids sit.
- Routinely clean using only recommended stone-safe cleaners.
- Consider having the quartz professionally re-polished every 2-3 years.
