How to Clean Quartz: A Step-by-Step Guide

Quartz is a popular countertop material because it is durable and non-porous, but it still needs regular cleaning to keep its shine. This guide covers the safest way to clean quartz, what to avoid, and how to fix common problems like streaks or stubborn stains.

What You’ll Need

Mild dish soap (like Dawn or Seventh Generation)
Warm water
Soft microfiber cloth or sponge
Rubbing alcohol (70% isopropyl) for disinfecting
Glass cleaner (optional, for streak-free shine)
Soft-bristled brush (for grout lines or textured quartz)

Step-by-Step

Clear the surface – Remove all items from the quartz countertop, including appliances, jars, and cutting boards. This gives you full access and prevents scratching from moving things around.
Rinse with warm water – Run warm water over the surface to loosen loose dirt and food particles. If you have a large countertop, use a spray bottle filled with warm water to mist it.
Mix a cleaning solution – In a small bowl, mix a few drops of mild dish soap with warm water. Do not use citrus-based soaps or degreasers, as the acid can damage the resin in quartz.
Wipe with a soft cloth – Dip a microfiber cloth or sponge into the soapy water, wring it out well, and wipe the entire surface in gentle, circular motions. Pay extra attention to areas near the sink or stove where grease and food splatter accumulate.
Rinse and dry – Rinse the cloth thoroughly with clean water, then wipe the countertop again to remove any soap residue. Dry with a separate clean, dry microfiber cloth to prevent water spots and streaks.
Disinfect (optional) – For a deeper clean, spray a 50/50 mix of rubbing alcohol and water onto the surface and wipe with a clean cloth. This kills bacteria without damaging the quartz. Do not use bleach or ammonia-based cleaners.

Common Mistakes

Using acidic cleaners – Vinegar, lemon juice, and products containing citric acid can etch the resin binder in quartz, leaving dull spots that are hard to fix.
Abrasive scrubbing – Scouring pads, steel wool, or abrasive powders will scratch the surface. Even if the scratch is fine, it traps dirt and makes the countertop look dull.
Leaving spills for too long – While quartz is non-porous, some liquids like red wine, coffee, or oil can leave a temporary stain if left to sit. Wipe spills immediately.
Using harsh chemical cleaners – Bleach, oven cleaner, and drain cleaner can break down the resin and cause discoloration. Always check the label for pH balance.

Tips

Use a cutting board – Even though quartz is scratch-resistant, it is not scratch-proof. Always cut on a board to protect the surface.
Use trivets for hot pans – Quartz can handle moderate heat, but sudden temperature changes can cause cracks. Always place hot pots on a trivet or cooling rack.
Clean up oil quickly – Oil can leave a film that attracts dust. Use a degreaser specifically labeled safe for quartz if you cook often.
Buff for shine – After drying, give the surface a quick buff with a dry microfiber cloth to restore its natural luster.
Test unknown cleaners – Before using a new product, test it on a small, inconspicuous area first to ensure it doesn’t cause damage.

Troubleshooting

Streaks after cleaning – This usually means soap residue is left behind. Rinse with clean water and dry thoroughly. For stubborn streaks, wipe with a 50/50 alcohol and water solution.
Dull spots – If you used an acidic cleaner, the resin may be etched. Try buffing the area with a quartz-safe polishing compound. If that doesn’t work, you may need to call a professional to re-polish.
Sticky residue – For dried-on food or adhesive, gently scrape with a plastic putty knife, then clean with soapy water. Do not use metal scrapers.
Water spots – Hard water can leave mineral deposits. Wipe with a damp cloth and then dry thoroughly. For stubborn spots, use a mixture of water and a little white vinegar (test first) – but rinse immediately and dry.
Discoloration – If a chemical caused yellowing, it may be permanent. Contact the manufacturer for advice. In most cases, the only fix is professional resurfacing.

Frequently Asked Questions

Can I use vinegar to clean quartz?

No. Vinegar is acidic and can dull the surface over time. Stick to mild soap and water.

Is quartz safe to clean with bleach?

No. Bleach can damage the resin binder. Use a gentle disinfectant like rubbing alcohol diluted with water.

How often should I clean quartz countertops?

Wipe down daily with soapy water to prevent buildup. Do a deeper clean with alcohol once a week.

Can I use a steam mop on quartz?

It’s not recommended. High heat and steam can stress the resin. Use a damp cloth instead.

Why does my quartz look streaky after cleaning?

Streaks are usually from soap residue or hard water. Rinse thoroughly and dry with a clean cloth.

Can I use a magic eraser on quartz?

No. Melamine foam is abrasive and will scratch the surface. Use a soft sponge.
