How to Care for Quartz Countertops: The Complete Maintenance Guide

One of the most frequent questions we get after a quartz countertop installation is: 'What do I need to do to maintain it?' The honest answer — and the reason so many homeowners choose quartz in the first place — is remarkably little. Quartz is the most maintenance-friendly countertop surface available. No sealing. No waxing. No annual treatments.
But 'low maintenance' is not the same as 'no maintenance,' and there are a handful of mistakes that can damage quartz faster than years of normal cooking and cleaning. This guide tells you exactly what quartz needs, what it does not need, and what to never do to it — so your investment stays beautiful for as long as you own your kitchen.
Quartz does not require maintenance. It requires knowing what to keep away from it, which is a shorter list than you might expect. |
What Makes Quartz Low-Maintenance
Quartz countertops are engineered from approximately 90–94% crushed quartz crystals bound with polymer resins. The resin binder fills the microscopic voids between quartz particles, producing a surface that is essentially non-porous. Non-porous means liquids cannot penetrate — wine, coffee, olive oil, citrus juice, and virtually every common kitchen substance sits on the surface rather than absorbing into it.
This is the fundamental difference from granite and natural stone, which are genuinely porous and absorb staining agents over time if not properly sealed. Quartz requires no sealing because it does not need sealing — the material itself does not absorb anything.
Daily Cleaning: Simple and Fast
Routine cleaning
For daily cleaning after cooking and preparing food, a damp cloth or paper towel with a small amount of mild dish soap is all that is needed. Wipe the surface, rinse with clean water, and dry — the whole process takes under a minute. The dish soap breaks down cooking grease and food residue without affecting the quartz surface or its finish.
For stubborn messes
For dried or stuck food — the pan that boiled over, the sauce that sat overnight — dampen a cloth with warm water, let it sit on the stuck material for a few minutes to soften it, then wipe clean. For persistent residue, a small amount of isopropyl alcohol (rubbing alcohol) on a cloth will cut through grease and dried material without damaging the surface.
What Not to Use on Quartz
This is the more important list. Several common kitchen cleaning products — things that seem reasonable or even gentle — can damage quartz over time or in a single application.
⛔ Products to NEVER Use on Quartz: Bleach or bleach-based cleaners break down the resin binder with repeated use. Oven cleaners — highly alkaline; will etch and dull the surface. Drain cleaners poured on the surface — same alkaline damage risk. Acetone (nail polish remover) — dissolves the resin binder; a single application can permanently damage the surface. Abrasive scrubbers or steel wool — scratch the finish. Highly acidic cleaners (muriatic acid, strong vinegar solutions) — though quartz is acid-resistant, prolonged contact with concentrated acids causes surface degradation. Furniture polish or wax — creates a residue buildup that dulls the finish. |
Note on the acid question: quartz is significantly more acid-resistant than marble. A splash of lemon juice or vinegar wiped up promptly will not harm quartz. The concern is concentrated, prolonged contact, and cleaning products specifically formulated with high acid concentration.
Heat: The One Area to Be Careful
Quartz's most discussed limitation is heat resistance. While quartz is manufactured to withstand normal kitchen temperatures, the polymer resin component is susceptible to thermal shock — sudden, intense, localized heat — in a way that pure stone is not.
A hot pan placed directly on quartz from a stovetop can cause discoloration, cracking, or surface damage in the area of contact. This is not a defect in the quartz — it is a known characteristic of the material. The solution is simple: use trivets and hot pads for any item coming directly off a heat source. This is a habit most home cooks develop naturally, and it fully protects the surface.
What quartz handles without concern: warm pans that have been sitting off the heat, normal hot water, hot mugs and cups, and the ambient heat of cooking in an active kitchen.
Cutting and Scratching
Quartz is very hard — approximately 7 on the Mohs scale, harder than most natural stones. Under normal kitchen use, it does not scratch easily. However, the recommendation is to always use a cutting board for food preparation — not because quartz will visibly scratch from a single use, but because repeated knife contact over the years will eventually dull the finish in cutting areas, and because cutting boards protect both your countertop and your knife edges (a cutting board is kinder to knife sharpness than stone).
The abrasive concern in a Lowcountry kitchen is less knife-on-quartz and more grit. Sand tracked in on shoes or bags and left on the countertop surface can scratch quartz if dragged across it. Wipe grit off the surface before wiping with a cloth — dragging a cloth over sand-covered quartz is the most common cause of fine surface scratching in coastal homes.
Stain Scenarios — Specific Guidance for Common Kitchen Events
SUBSTANCE / EVENT | WHAT TO DO | WHAT NOT TO DO |
Wine, coffee, tea | Wipe promptly with a damp cloth; mild soap if needed | Nothing special — quartz resists these easily |
Olive oil/cooking grease | Dish soap + warm water; isopropyl alcohol for dried grease | Abrasive scrubbers |
Permanent marker | Isopropyl alcohol on a cloth usually removes completely | Nail polish remover (acetone) |
Nail polish | Isopropyl alcohol applied carefully — test first | Nail polish remover; acetone damages quartz |
Dried/caked food | Soak with warm, damp cloth, then wipe — do not force-scrape | Metal scrapers, abrasive pads |
Paint | Isopropyl alcohol, while wet; consult us if dried | Paint thinner or chemical strippers |
Bleach splash (accidental) | Rinse with water immediately; typically, no damage from brief contact | Do not let bleach sit or use bleach cleaners routinely |
Long-Term Appearance: What to Expect Over Years
One of quartz's genuine advantages over natural stone is its consistent, predictable appearance over time. Because it is engineered rather than quarried, the material does not change character over the years the way marble patinas or granite darkens. A well-maintained quartz countertop looks essentially the same in year fifteen as it did on installation day.
The only common long-term appearance change in quartz is finish dulling from repeated contact with cleaning products outside the recommended range, or from abrasive cleaning practices over the years. Both are preventable with the guidelines in this post. The quartz we install in Lowcountry kitchens is backed by manufacturer warranties of 10–15 years — and with proper care, the material performs beautifully well beyond that.
🏠 From the CDC Team: When we install quartz countertops in your kitchen, we leave behind the manufacturer's care guidelines specific to your product. Every quartz manufacturer has slightly different recommendations — particularly regarding approved cleaning products. When in doubt, simple dish soap and warm water is the safe choice for every brand and every application. |
