How to Care for Your Countertops After Installation
Short answer: for the first day or two, treat your new countertops gently while everything cures. After that, everyday care is simple — clean with mild soap or a pH-neutral stone cleaner and a soft cloth, always use trivets under hot pans and a cutting board under knives, and wipe up spills promptly, especially acidic ones on natural stone. Natural stone is sealed at installation and re-sealed periodically; quartz and porcelain never need sealing. Do that, and your countertops will look new for decades.

The first 72 hours
Your installation includes epoxy-bonded seams where two slabs meet, silicone/caulk at the joints where the countertop meets the walls and cabinets, and — on natural stone — a fresh sealer. Give these time to cure:
Wait about 24 hours before heavy sink use or getting the caulked wall-and-cabinet joints wet.
Don't sit, stand, or set heavy loads on the countertops or overhangs while everything sets.
Skip harsh cleaners for the first day or two — plain water and a soft cloth are perfect.
Everyday cleaning: what to use (and avoid)
Use warm water with a little mild dish soap, or a pH-neutral stone cleaner, and a soft cloth or non-scratch sponge.
Avoid abrasive scouring pads and powders, and harsh chemicals like bleach, ammonia, and vinegar or other acids — these can dull natural stone and, over time, degrade the finish on quartz too.
For dried-on messes, let warm soapy water soak briefly rather than scrubbing hard.
The three things that cause most damage
Nearly every damaged countertop we see comes down to heat, knives, or weight.
Heat. Always use trivets or hot pads. This is essential on quartz — heat can scorch the resin — and smart on all surfaces to protect sealers and prevent thermal shock.
Knives. Always cut on a cutting board. Even hard stone can dull knives and be scratched by grit, and cutting directly voids most surface warranties.
Weight & impact. Don't stand on counters or drop heavy objects near edges, corners, and cutout areas around sinks and cooktops — the most vulnerable points.
Sealing: which surfaces need it
Natural stone (marble, quartzite, granite) is sealed at installation and should be re-sealed periodically — often every year or few years depending on the stone and how hard the kitchen works. Quick test: drip a little water on the surface; if it soaks in and darkens within a few minutes, it's time to re-seal.
Quartz never needs sealing — it's non-porous.
Porcelain / sintered stone (Dekton, Neolith class) never needs sealing — one of the most maintenance-free surfaces available.
Spills to wipe up fast
On natural stone especially, acidic spills are the main enemy. Blot — don't wipe and spread — these promptly: wine, coffee, and fruit juice; lemon, tomato, vinegar, and other acidic foods; oils and anything greasy. Marble and some quartzites can etch (leave a dull mark) from acids even when sealed, because sealing prevents staining, not etching. Prompt cleanup is the best protection.
Quick guide by material
Quartz. No sealing. Mild soap and water. Always use trivets — heat is its one weakness.
Natural stone. pH-neutral cleaner, re-seal periodically, blot acidic spills fast, use trivets and cutting boards.
Porcelain / sintered stone. Nearly bulletproof — heat-, scratch-, and stain-resistant, no sealing. Still use a cutting board to protect your knives and avoid sharp impacts on edges.
FAQ
How soon can I use my countertops after installation?
You can use them right away for light tasks, but wait about 24 hours before heavy sink use or getting the caulked wall-and-cabinet joints wet, and avoid placing heavy loads while everything cures.
What's the best everyday cleaner for countertops?
Warm water with a little mild dish soap, or a pH-neutral stone cleaner, with a soft cloth. Avoid vinegar, bleach, ammonia, and abrasive pads.
Do I need to seal my new countertops?
Only natural stone needs sealing — it's sealed at install and re-sealed periodically. Quartz and porcelain/sintered stone never need sealing.
How often should I re-seal natural stone?
It varies by stone and use — often every year to a few years. Use the water-drop test: if water soaks in and darkens the stone within a few minutes, it's time to re-seal.
Can I put hot pans directly on my countertop?
Always use a trivet. It's critical on quartz, where heat can damage the resin, and it protects sealers and prevents thermal shock on stone and porcelain.
Can I cut directly on my countertops?
No — always use a cutting board. It protects the surface, keeps your knives sharp, and preserves your warranty.
What removes a stain or etch mark?
Stains on natural stone can often be drawn out with a poultice; etch marks (dull spots) may need light polishing. Reach out before trying aggressive products and we'll advise on your specific surface.
Are quartz and porcelain really maintenance-free?
They're the lowest-maintenance surfaces we install — no sealing, easy cleanup. Just use trivets on quartz and cutting boards on everything to keep them flawless.
