Can I use vinegar to clean new granite countertops after installation in Ottawa?

No, you should never use vinegar on granite countertops — whether new or old, it is an easy post-installation cleaning mistake to make. Vinegar is acidic, and granite is a natural stone that contains minerals sensitive to acid. Even diluted vinegar will etch the surface of granite over time, creating dull spots, removing the polished finish, and eventually compromising any sealant that was applied after installation. The damage may not be visible after one cleaning, but repeated use can noticeably degrade your countertops.

What to Use Instead on New Granite After Construction

For post-construction cleaning of newly installed granite countertops, the safest and most effective approach is a pH-neutral stone cleaner designed specifically for natural stone surfaces. Stone cleaners are sold at hardware stores and stone suppliers; look for one labelled safe for sealed granite. These cleaners are formulated to clean thoroughly without disrupting granite's mineral structure or stripping the sealant.

For the initial post-installation clean, your granite installer should have wiped down the countertops, but construction dust from surrounding work settles quickly. Start by wiping the entire surface with a dry microfibre cloth to remove loose dust particles. This is critical because wiping a wet cleaner over gritty construction dust drags abrasive particles across the polished surface. After dry dusting, spray your pH-neutral stone cleaner and wipe with a clean, damp microfibre cloth, then dry immediately with a separate cloth to prevent water spots.

Construction-specific residues on new granite require targeted treatment. Silicone caulk residue from sink or backsplash installation can be carefully removed with a plastic scraper and a small amount of isopropyl alcohol on a soft cloth. Adhesive residue from protective films or tape responds well to an adhesive remover labelled safe for sealed stone, wiped off promptly and followed with your pH-neutral cleaner. Grout haze from adjacent tile work is trickier — use a grout haze remover that is labelled as safe for natural stone, not a standard acidic grout cleaner which will damage the granite just like vinegar would.

Ask your installer whether the granite was sealed at the fabrication shop or needs sealing on site, and avoid wet cleaning until any new sealer has cured for the time the product label gives. If the countertops were not sealed, an impregnating stone sealer is a worthwhile step that makes ongoing cleaning much easier.

For a complete post-construction kitchen cleanup that includes proper granite care along with all other surfaces, ask cleaning companies for itemized written quotes, and ask which products they use on natural stone so you know they treat each surface correctly.
