Most countertop problems I get called back for were preventable. Not because the homeowner did anything dramatic, but because of small habits that quietly add up: a vinegar spray bottle living under the sink, a magic eraser used for the wrong job, or a sealing schedule that drifted from "annual" to "I forget when we last did it." Here is exactly how to keep your stone looking the way it did the day we set it.
Daily cleaning, the boring truth
For both quartz and granite, your everyday cleaner is warm water with a few drops of regular dish soap on a soft cloth. That's it. There is no exotic product that will make your counter look better than gentle soapy water used regularly. We sell stone-safe spray cleaners at the warehouse if you prefer the convenience of a bottle, and they're fine, but they're a luxury, not a necessity.
A handful of practical rules:
- Wipe spills as they happen. Even on quartz, sitting coffee or wine for a full day is harder to remove than a thirty-second wipe.
- Use a soft microfiber cloth. Rough scouring pads scratch the polish on both materials. Save them for cast iron.
- Rinse with clean water and dry with a clean cloth. Especially in our dry winters, this prevents mineral spotting from hard water.
- Once a week, do a thorough clean. Soapy water, a wipe-down, a rinse, a dry. Five minutes.
For granite specifically, a pH-neutral stone cleaner (we recommend MB-5 or any product labelled "stone safe") is a small upgrade over dish soap because it leaves no residue at all. Quartz tolerates either equally well.
What NOT to use, and why
This is the section where most homeowners learn something new. Several products that are perfectly fine for laminate or tile will gradually damage stone counters. The damage is usually slow, which is what makes it sneaky.
Vinegar, lemon juice, and any acidic cleaner
Acid eats stone. Granite is mostly silica and feldspar, both of which are reasonably acid-resistant, but the polished surface and any sealer on top are vulnerable. Marble (which we do install in bathrooms) is far worse, but even granite will dull over months of vinegar exposure. Quartz handles acid better but the polymer binder is not infinitely tolerant. Skip the vinegar entirely on stone. If you want a glass-and-mirror cleaner, get one labelled stone-safe.
Bleach and ammonia
Bleach can lighten the colour of dark granite over time and will weaken any impregnating sealer instantly. Ammonia (Windex, most degreasers) is mildly alkaline and a regular nuisance to sealers as well. Neither is a one-spill emergency, but used routinely they shorten the life of your finish. If you absolutely need to disinfect, dilute hydrogen peroxide is a stone-safe alternative.
Abrasive scrubbers and powders
Steel wool, green scotchbrite pads, and gritty cleansers like Comet will dull the polish on granite and quartz in ways you can't undo with cleaner alone. If something is genuinely stuck, soak it with warm soapy water for ten minutes and try again. Patience beats abrasion.
The magic eraser problem
Melamine sponges (the white "magic" ones) are micro-abrasive. They work because they're sanding the top layer off whatever you're cleaning. On a polished stone counter, that means dulling. Save them for sinks and walls.
Heat protection, every time
I covered this in the quartz vs granite article: granite is heat-proof in any kitchen scenario, quartz is rated to about 150 Celsius. But the practical advice is the same for both materials: use a trivet, every time. Not because granite needs one (it doesn't), but because a trivet costs three dollars and saves you the question of whether this particular pan is too hot.
The two situations to absolutely never skip a trivet:
- Cast iron straight off the burner.
- A slow cooker or instant pot that's been running for hours. The base of these gets hot enough to scorch quartz over time.
Cutting boards, always
Granite and quartz are both harder than your knives. That's the issue. If you cut directly on stone, you will dull your blades quickly, and on quartz you can also leave fine scratches in the polished surface that catch light. Use a wood or plastic cutting board. Your knives will thank you, and so will the counter.
Sealing schedule for granite
We seal every granite counter at install with a quality impregnator. In the dry Yukon climate, that seal typically lasts 1 to 3 years depending on:
- How porous your specific granite is (light granites soak up more, dark granites less)
- How often you use alkaline cleaners that strip sealer over time
- How heavy the use is (a busy family kitchen wears faster than a vacation cabin)
The water test tells you when it's time. Drip a tablespoon of water onto the counter and watch it for 10 minutes. If it beads up and stays beaded, the seal is fine. If it darkens the stone or absorbs in, it's time to re-seal. We sell the same impregnator we use, and the application is genuinely easy: clean the counter, wipe on the sealer with a soft cloth, wait 5 minutes, wipe off the excess, done. One bottle does a typical kitchen.
Quartz never needs sealing. Skip this whole section.
What to do if something stains
Quartz stains are almost always surface residue, not actual stains in the stone. A non-abrasive plastic putty knife (or even a fingernail) plus warm soapy water will lift 95 percent of "stains" people report. For dried sauce, dried wine, or dried coffee, a paste of baking soda and water left for fifteen minutes does the rest.
Granite can actually absorb a stain if the seal has worn. Oil stains (cooking oil, butter, salad dressing) are the most common. Mix baking soda with hydrogen peroxide into a thick paste, apply over the stain, cover with plastic wrap, leave overnight. The poultice draws the oil up out of the stone. It works almost every time on a fresh stain. Older stains may need two applications. For wine or fruit-juice stains on granite, swap the hydrogen peroxide for plain water and add a few drops of dish soap to the paste.
Chips and scratches
Small chips on the front edge of a counter, especially around sinks and dishwashers, are the most common damage we see. They happen when something hard (a cast iron pan, a heavy ceramic mug) clips the edge. Both quartz and granite can be repaired with a colour-matched epoxy. We carry the matching kit for any stone we install. For deeper damage we come out and do it in person, usually a 30-minute job.
Hairline scratches on quartz, the most common cosmetic complaint we hear, are usually not actual scratches in the stone but residue (knife marks from a chef's knife dragged across the surface, for example). A non-abrasive cleaner like Bar Keepers Friend Soft Cleanser will lift these. If after that the scratch is genuinely in the resin, a polishing compound from us will buff it out.

When to call us back
Most of the time, you won't need to. But these are the situations where it's genuinely worth a phone call instead of an internet rabbit hole:
- A chip on a visible front edge that's bigger than a pencil eraser.
- A stain that hasn't lifted after two attempts at a poultice.
- A seam that's started to show a hairline gap or where the caulk has pulled away (this happens occasionally with cabinet movement).
- An undermount sink that feels loose or wiggles when you press on it.
- You're planning to replace your sink or faucet and want it done correctly without damaging the cutout.
- You bought the house from someone who didn't know how to care for stone, and you want a professional reseal and polish.
One number, no surprises. Our work comes with a real Quality Pledge, and our maintenance advice is free over the phone. If something looks off, call (867) 335-8226 before you experiment. We've seen most situations and can usually tell you in five minutes whether it's a wipe-and-go or a worth-a-visit.
Treat your stone gently, wipe up spills, use a trivet, and check the granite seal once a year. Do those four things and your counters will outlast the cabinets they sit on.
