How to Clean Granite Countertops: Do's and Don'ts

Protect your granite countertop investment with proper cleaning techniques. What to use, what to avoid, and how to maintain the shine.

Why Granite Needs Special Care

Granite is a beautiful, durable natural stone — but it is also porous. Without proper care, granite absorbs liquids that stain, loses its polished shine from harsh chemicals, and can develop etching from acidic substances. Many common household cleaners damage granite over time. The good news: proper granite care is simple once you know the rules. Many NC Triangle homes, especially in Cary, Apex, and Wake Forest, feature granite countertops that represent a significant investment worth protecting.

Daily Granite Cleaning

For daily cleaning, use warm water and a few drops of pH-neutral dish soap on a soft cloth or sponge. Wipe surfaces clean and dry with a separate soft cloth — do not let water pool on granite, as it can seep into pores and cause dark spots. That is genuinely all you need for daily maintenance. Skip the fancy granite-specific sprays for everyday use — they build up over time and can make surfaces hazy.

What to Never Use on Granite

Never use: vinegar, lemon juice, or any acidic cleaner (they etch the polished surface). Never use: bleach or ammonia-based cleaners (they strip the sealant). Never use: abrasive cleaners, scouring pads, or steel wool (they scratch the polish). Never use: generic all-purpose cleaners like Windex or 409 (they contain chemicals that degrade sealant). When in doubt, use only warm water and mild dish soap — it is safe and effective.

Sealing and Professional Care

Granite should be professionally sealed every 1-2 years to maintain its protective barrier. Test if your granite needs resealing by placing a few drops of water on the surface — if it darkens within 5 minutes, it is time to reseal.
