Quartzite countertops are a stunning and durable addition to any modern kitchen. While true quartzite is incredibly hard and naturally resistant to both scratching and acid etching, many varieties on the market are actually 'soft quartzites' that behave more like marble.
Because of this industry crossover, knowing how to clean quartzite countertops safely is essential to preserving their protective sealer and natural shine. Fortunately, proper quartzite countertop cleaning is straightforward once you know what works and what to avoid.
What never to use on quartzite
Before you reach into your cleaning cabinet, you must be aware of products that can strip your stone's protective sealer or damage mislabeled soft quartzite.
- Harsh acids: You should strictly avoid vinegar, lemon juice, and citric acid cleaners.
- Chemical cleaners: It is equally important to skip bleach, ammonia-based sprays, and heavy-duty bathroom cleaners.
- Abrasives: Never use abrasive scouring pads, steel wool, or gritty scrubbing powders that can scratch the surface finish.
Do not assume that natural cleaners are inherently safe for your kitchen. A DIY vinegar and lemon spray will dull a sealed countertop quickly, so you should stick exclusively to pH-balanced dish soap or specialized stone cleaners.
Safe quartzite cleaning methods
1. The daily cleaning routine
Your daily cleaning routine should be gentle enough to maintain the stone's sealer while effectively removing daily grime.
To clean your countertops, mix warm water with a few drops of mild, pH-neutral dish soap in a clean spray bottle. Then, spray the countertop lightly and wipe the surface in circular motions using a soft microfiber cloth or a non-abrasive sponge.
Once the counters are clean, rinse them thoroughly with a fresh, damp cloth to remove any leftover soap residue. Skipping this step allows soap buildup to dull the finish over time.
Finally, buff the entire surface dry with a microfiber towel to prevent water spots and achieve a streak-free shine.
2. Handle spills immediately
While true quartzite resists acid, the protective sealer on top can still be compromised if spills are left to sit. Liquid assets like wine, coffee, citrus juice, olive oil, and greasy foods can penetrate the stone if the sealer is worn down.
You should make it a habit to wipe up spills instantly before they have a chance to set into the surface. Keeping paper towels within arm’s reach of your main work areas is a simple way to prevent the vast majority of countertop staining.
3. Stain removal
If an organic substance like coffee or red wine leaves a dark mark, you can draw it out using a baking soda poultice. Mix baking soda and water together until it forms a thick paste, then apply it directly over the stain.
Cover the area with plastic wrap, tape down the edges to seal it, and let it sit undisturbed for twenty-four to forty-eight hours. Afterward, remove the wrap and wipe the area clean with a damp cloth.
The annual sealer test
Because quartzite is a natural stone, it relies on a chemical sealer to keep liquids pooling on the surface rather than soaking in. You should test the integrity of your sealer at least once a year by pouring a few drops of water onto a high-use area of the counter.
If the water beads up, your sealer is doing its job and your stone remains protected. If the water soaks into the stone within a few minutes and leaves a temporary dark spot, you should apply a high-quality natural stone sealer immediately to prevent future damage.
