Stone care frequently asked questions

Discover essential guidance on daily cleaning, sealing schedules, heat tolerance, and stain prevention to keep your stone countertops and surfaces looking pristine.

How should I clean my stone countertops daily?

For everyday cleaning, use warm water, a few drops of mild dish soap, and a soft microfiber cloth. Rinse thoroughly with clean water and dry with a soft towel to prevent water spots. Avoid acidic or abrasive cleaners like bleach, vinegar, or ammonia, which can degrade sealers and dull natural stone surfaces.

How often do natural stone surfaces need to be resealed?

Most granite and quartzite surfaces benefit from resealing every one to two years, while softer stones such as marble may require sealing more frequently. You can test your surface by placing a few drops of water on the stone; if the water no longer beads and begins to soak in after 10–15 minutes, it is time to reseal.

Can I place hot pots and pans directly onto the stone?

Although natural stones like granite withstand high temperatures, sudden temperature shifts—known as thermal shock—can cause hairline cracks or compromise surface sealers. We always recommend using trivets or hot pads beneath heated cookware, slow cookers, and electric griddles.

What should I do if a spill occurs?

Blot spills immediately with a paper towel or soft cloth rather than wiping, which spreads the liquid. Liquids like red wine, coffee, citrus juices, and cooking oils can penetrate porous stone if left standing. Clean the area promptly with mild soap and warm water.

How do I remove stubborn stains or water rings?

For organic or oil-based stains that have settled into the stone, a specialized poultice paste formulated for natural stone can safely draw out the substance without harming the surface polish. Contact our team in Fletcher, NC, if you need advice on stubborn stains.

Can I cut food directly on my stone countertop?

While natural stone is exceptionally hard and scratch-resistant, cutting directly on your countertops will quickly dull your kitchen knives and can leave light metal marks or wear down the protective sealant. We consistently advise using cutting boards.

How should I care for natural stone fireplace surrounds?

Dust fireplace surrounds regularly using a dry microfiber duster or a soft brush attachment on a vacuum. For soot or residue, wipe gently with a damp cloth and a pH-neutral stone cleaner. Avoid harsh chemical oven or fireplace cleaners that can etch or discolor the natural stone.

What products should I avoid using on natural stone?

Never use products containing lemon juice, vinegar, bleach, ammonia, or abrasive scrubbing powders. These harsh chemicals strip the protective sealant and can cause surface etching, especially on calcium-based stones like marble and limestone.
