How to Clean and Care for Quartzite Countertops

Quartzite has a reputation as one of the toughest natural stone benchtop materials, and for genuine quartzite that reputation is earned. It forms when sandstone is compressed and heated deep underground until the quartz grains fuse together, leaving a surface that is harder than granite and far more resistant to everyday wear than marble. But quartzite is also one of the most confusing labels in the stone trade. Some slabs sold under that name are actually dolomitic marble, which behaves nothing like true quartzite once an acidic splash or the wrong cleaner meets it. Knowing which stone is actually on your bench changes how carefully you need to clean it.

The good news is that quartzite care is simple once you know the few things to avoid. Here is the honest, practical routine, along with what a sealer can and cannot do for you.

Daily Cleaning for Quartzite Countertops

Wipe the surface down after use with warm water and a few drops of a pH-neutral dish soap, applied with a soft microfibre cloth. Skip abrasive sponges, scouring pads and cleaning powders, all of which can scratch the finish over time even on a hard stone. Dry the benchtop after cleaning rather than air drying, which helps prevent hard water spotting around taps and sinks.

What to Avoid on Quartzite

Even genuine quartzite, while more acid resistant than marble, is not immune to acid. Repeated contact with wine, coffee, tomato sauce, vinegar and citrus can dull the surface over time. If your benchtop is actually dolomitic marble sold as soft quartzite, it can etch, leaving a dull mark, far more readily, sometimes on first contact. Bleach and ammonia based glass cleaners can also strip away any sealer sitting in the stone’s pores, so keep them off the benchtop entirely. Blot spills rather than wiping them across the surface, and rinse away any acidic splash as soon as you notice it. It is also worth checking cookware and appliances for rough or unfinished bases before sliding them across the stone, since dragging a heavy pot or mixer can scuff even a hard surface.

Removing Stains Without Damaging the Stone

For oil based stains such as cooking oil or butter, a poultice of baking soda mixed with water, left on the mark overnight under plastic wrap, will draw the oil back out. For hard water marks or soap scum, stick to a stone safe, pH-neutral cleaner. Avoid steel wool or kitchen bleach, both of which can scratch or discolour the surface permanently. If a stain has set in over time, a stone restoration professional can advise on options a home remedy cannot reach. Acting quickly always beats any remedy, so keep a soft cloth within reach in the kitchen rather than in a cupboard down the hall.

Sealing Quartzite: What It Actually Does

Many installers recommend sealing quartzite at installation and again every year or two. A sealer soaks into the stone’s pores and slows how quickly liquids are absorbed, buying you time to wipe up a spill before it stains. What a sealer cannot do is stop acid etching. That reaction happens within the stone’s own crystal structure, and no coating sitting on top of the stone changes it. The same is true for marble, which is why our guide comparing sealer versus protection film reaches the same conclusion for both stones. A sealer manages risk. It does not remove it, and it needs reapplying as it wears down.

Complete, Long-Term Protection with DURAFLEX

The only way to stop both staining and etching on quartzite is a physical barrier between the stone and whatever lands on it. That is what DURAFLEX does: an optically clear, heat-activated self-healing polyurethane film, heat-sealed to the stone at installation by automotive-trained specialists, and engineered for UV stability so it will not yellow the way an ageing sealer job can. It carries an up-to-10-year warranty and is installed across VIC, NSW, QLD, SA and TAS. Because engineered stone and quartzite carry the same protection case as marble, owners can request an instant estimate for a quartzite benchtop with the same confidence as for a marble one. For a full walkthrough of how the process works, see our complete guide to protecting stone benchtops, or visit the DURAFLEX protection film page to see the finish up close.

Frequently asked questions

Is quartzite really more durable than marble?

Genuine quartzite is a metamorphic rock made almost entirely of fused quartz crystals, which makes it harder and more resistant to everyday scratching and acid than calcite based stones like marble. The catch is that some countertops marketed as quartzite are actually dolomitic marble, which does not share that resistance. If you are not certain which stone is on your benchtop, treat it with the same care as marble until a fabricator confirms otherwise.

Can I use vinegar or lemon juice to clean quartzite?

No. Vinegar, lemon and other acidic cleaners can dull genuine quartzite over time and can etch dolomitic soft quartzite almost immediately. Stick to warm water and a pH-neutral soap, and rinse off any acidic spill, such as wine, coffee or tomato sauce, as soon as you notice it.

Do I need to seal my quartzite countertop?

Sealing is common practice and does slow how fast liquids soak into the stone, which is genuinely useful. It does not stop acid etching, because that reaction happens within the stone’s own mineral structure rather than on its surface. DURAFLEX film addresses both risks at once, which is why many owners choose it instead of a sealer that needs reapplying every year or two.

Does DURAFLEX film change how quartzite handles heat?

DURAFLEX can safely handle hot items like coffee mugs and freshly microwaved plates. For anything hotter, such as cookware from a gas flame or oven, we recommend using trivets to preserve both the film and your stone.
