Quartz is one of the easiest countertop surfaces to live with, which is a big part of why it has become the go-to choice in Phoenix kitchens and bathrooms. It does not need sealing, it shrugs off most everyday spills, and it cleans up with little more than soap and water. But "low-maintenance" is not the same as "no rules," and a few habits will keep your quartz looking new for decades instead of slowly dulling out.
This guide covers exactly how to clean quartz day to day, what to keep away from it, and the handful of Phoenix-specific issues, intense sun and hard water, that affect quartz here more than in other parts of the country. Everything below applies to the quartz Superior Stone & Cabinet installs across the Valley, including the Silestone line.
Times you will ever need to reseal quartz. The resin binder makes the surface non-porous for life. The single biggest care advantage quartz has over granite and other natural stone.
Why Quartz Is Low-Maintenance
Quartz countertops are engineered stone. They are made from roughly 90 percent ground natural quartz combined with resins and pigments, then formed into slabs. That resin is the key to the whole care story: it binds the surface into a solid, non-porous material that liquids cannot soak into.
Because it is non-porous, quartz does three things well with very little effort from you. It resists stains, since spills sit on top of the surface instead of being absorbed. It resists bacteria for the same reason, which is part of why it is popular for kitchens and bathroom vanities. And it never needs sealing. The protection is built in at the factory and does not wear off, unlike the topical sealer that natural granite requires every year or two.
What quartz is not, however, is indestructible. The same resin that makes it easy to care for is sensitive to heat, harsh chemicals, and prolonged sun. Knowing those few limits is really all there is to caring for quartz.
Everyday Cleaning
Daily care could not be simpler. For routine cleaning, you need warm water, a few drops of mild dish soap, and a soft cloth or sponge. Wipe the surface down, then dry it with a clean towel to avoid water spots, which matters more in Phoenix than most places, as we will get to.
- Wipe spills as they happen, especially pigment-heavy ones like wine, coffee, turmeric, and tomato sauce
- Use a soft cloth, microfiber, or non-scratch sponge, never steel wool or abrasive pads
- Clean with mild dish soap and water, or a pH-neutral surface cleaner made for stone
- Dry the surface after cleaning to prevent hard water film from building up
- For a weekly refresh, wipe the whole surface with a quartz-safe cleaner
What to Avoid: Heat, Chemicals, Sun & Knives
Almost every quartz problem traces back to one of four things. Steer clear of these and your countertop will stay flawless.
Direct Heat
The resin in quartz is heat-sensitive. A hot pot, pan, or baking sheet set straight on the surface can scorch or discolor it, sometimes permanently. Always use a trivet or hot pad. In a Phoenix summer kitchen, cookware comes off the burner extremely hot, so this is the rule that catches people most often.
Harsh Chemicals
Bleach, ammonia, oven cleaner, drain cleaner, and high-alkaline or strongly acidic products can dull, etch, or discolor the finish. Skip abrasive scouring powders too. Pigment from these cleaners can also leave a haze. When in doubt, mild soap and water is the safe choice.
Prolonged Sun
Many quartz products are not rated for constant direct sunlight, and over time strong UV can fade the color or add a yellow tint. In Phoenix this is a real consideration for counters under big windows, and it is why standard indoor quartz should not be used for outdoor kitchens.
Cutting Directly
Quartz is hard and scratch-resistant, but a knife blade can still leave fine marks on a polished surface over time, and it dulls your knives fast. Always use a cutting board. It protects the countertop and your blades at the same time.
⚠ Never use these on quartz
- Bleach, ammonia, or other harsh household cleaners
- Abrasive scouring pads, steel wool, or scrubbing powders
- Acidic cleaners like undiluted vinegar or lemon for routine cleaning
- Hot cookware placed directly on the surface without a trivet
- Strong solvents such as paint thinner, nail polish remover with acetone left to sit, or bleach pens

Hard Water & Phoenix-Specific Care
Two things make caring for quartz in the Valley a little different from caring for it anywhere else: our water and our sun.
Hard Water and Mineral Film
Phoenix has some of the hardest water in the country. Over time, the dissolved minerals leave a cloudy film or chalky white spots on quartz, especially around faucets, in bathroom vanities, and anywhere water is left to air-dry. Quartz will not be damaged by hard water, but the buildup makes a polished surface look dull if it is never addressed.
The fix is mostly prevention: dry the surface after use, particularly around the sink. For film that has already formed, clean with mild soap and water or a quartz-safe cleaner, and lift any hardened deposits with a plastic putty knife or scraper held flat. Resist the urge to reach for an acidic lime-and-scale remover, the acids that dissolve mineral buildup can also wear down the quartz finish.
Sun and UV Exposure
Phoenix gets strong, direct sun year-round. For indoor counters under large or west-facing windows, that constant exposure can, over years, fade or yellow some quartz colors, lighter and pure-white tones tend to show it most. If you have a sun-drenched counter, consider blinds or a UV-filtering window film on the sunniest exposures. And if you are dreaming of an outdoor kitchen, talk to a designer about UV-stable materials rather than assuming indoor quartz will hold up to Arizona patio sun.
Removing Tough Spots and Stains
Most messes wipe away with soap and water. For the stubborn ones, here is the safe escalation path, always moving from gentlest to strongest, and never jumping straight to abrasives.
Dried-On Food, Grease, or Gum
Let warm soapy water soften the spot for a minute, then lift it with a plastic putty knife or the edge of a credit card held flat against the surface. Follow with a soapy wipe. Never use a metal blade or a scouring pad to scrape quartz.
Ink, Marker, or Adhesive Residue
Apply a small amount of isopropyl (rubbing) alcohol to a cloth, gently work the spot, then rinse with water and dry. Isopropyl alcohol is safe for quartz and handles most permanent marker, label adhesive, and similar marks.
Stubborn Stains
For a mark that will not budge, use a non-abrasive cleaner formulated for quartz or stone, following the product directions, and finish with a clean-water rinse. If a stain still resists, contact your installer rather than trying harsher chemicals that could damage the finish.
Your Quartz Care Schedule
Caring for quartz takes very little time. Here is the whole routine at a glance.
Wipe and Dry
Wipe spills as they happen and give high-use areas a quick clean with mild soap and water. Dry the surface around sinks to keep hard water spots from forming. That is the entire daily job.
Full Surface Clean
Wipe down the whole countertop with a pH-neutral or quartz-safe cleaner to keep the polish even and lift any light film before it builds up. Buff dry with a microfiber cloth.
Spot Treatment
Scrape dried-on spots with a plastic scraper, treat ink or adhesive with isopropyl alcohol, and clear hard-water film around faucets. Only when something specific calls for it.
Resealing
Skip it entirely. Unlike granite, quartz never needs to be resealed. If anyone tells you your quartz needs an annual sealer, it does not.
Quartz vs. Granite Care
If you are weighing surfaces or you have a mix of both at home, it helps to know how their care differs. The short version: quartz asks for less ongoing maintenance, while granite tolerates heat better. Here is the side by side.
| Care Factor | Quartz | Granite |
|---|---|---|
| Sealing | Never needed | Reseal periodically |
| Daily cleaning | Soap and water | Soap and water |
| Heat tolerance | Use a trivet | More heat-tolerant |
| Stain resistance | Excellent (non-porous) | Good when sealed |
| Sun / UV | Limit direct sun | Very UV-stable |

Do quartz countertops need to be sealed?
No. Quartz is engineered from ground natural quartz bound in resin, which makes it non-porous. Unlike granite, it never needs to be resealed. The stain resistance is built in at the factory and lasts the life of the countertop. That is the single biggest care advantage quartz has over natural stone.
Can you put hot pots and pans on a quartz countertop?
It is not worth the risk. The resin that binds quartz is sensitive to high heat, and setting a hot pan or baking sheet directly on the surface can scorch or discolor it, sometimes permanently. Always use a trivet or hot pad, especially in a Phoenix summer kitchen, where cookware comes off the stove very hot.
What is the best cleaner for quartz countertops?
For everyday cleaning, warm water with a few drops of mild dish soap and a soft cloth is all you need. For a deeper clean, use a pH-neutral or quartz-safe surface cleaner. Avoid abrasive powders and scouring pads, which can dull the finish over time.
Can you use vinegar or bleach on quartz?
Both are best avoided for routine cleaning. Bleach, ammonia, and other harsh or high-alkaline cleaners can dull or discolor the resin, and acidic cleaners like vinegar and lemon can wear down the finish if used regularly. Stick to mild soap and water or a pH-neutral cleaner to keep the surface looking new.
Does quartz fade or discolor in the sun?
It can. Many quartz products are not rated for prolonged direct sunlight, and over time intense exposure can cause fading or a yellow tint. In Phoenix, keep that in mind for counters under large windows, and avoid standard indoor quartz for outdoor kitchens. Window coverings on the sunniest exposures help protect the color.
How do you remove hard water stains from quartz?
Phoenix has very hard water, so mineral film and white spots are common, especially around faucets and on bathroom vanities. Wipe the surface dry after use to prevent buildup, and clean existing deposits with mild soap and water or a quartz-safe cleaner. For hardened spots, a plastic scraper lifts deposits safely. Avoid acidic descalers, which can damage the finish.
Can you cut directly on a quartz countertop?
You should not. Quartz is very hard and scratch-resistant, but cutting directly on it dulls your knives and can leave marks on a polished finish over time. Use a cutting board to protect both the countertop and your knife edges.
Does quartz stain?
Quartz resists stains very well because it is non-porous, but it is not stain-proof. Spills like wine, coffee, turmeric, and oil should still be wiped up reasonably soon rather than left to sit for days. For most everyday messes, a quick wipe with soap and water keeps the surface clean.
