Granite is one of the toughest and most beautiful natural stones used in homes and businesses today. Its durability makes it a favorite for kitchen countertops, bathroom vanities, and even outdoor entertaining areas. But while granite can take a lot of wear, it’s not indestructible—especially when exposed to certain substances over time.
At Fuller Granite Repair, we’ve seen countless granite surfaces damaged by the same common culprits. To help you protect your investment, here are seven everyday items you should never leave sitting on your granite countertops.
1. Acidic Foods and Liquids
Citrus fruits, vinegar, wine, tomato sauce, and soda may seem harmless, but they contain acids that can dull the surface of granite over time. Even with a good sealant, prolonged contact can etch the stone or cause discoloration.
What to do:
Always clean up spills immediately and use cutting boards or coasters when working with acidic ingredients.
2. Oily Substances
Cooking oils, butter, lotion, and even some cosmetics can seep into unsealed or poorly sealed granite and cause dark stains that are difficult to remove. Oil stains are particularly common near cooktops and bathroom sinks.
What to do:
Keep oily items off the counter and store them in cabinets or on trays. Wipe surfaces regularly to remove residue.
3. Harsh Cleaning Products
Many people assume that granite can withstand any cleaner, but that’s far from true. Bleach, ammonia, and abrasive scrubbing pads can wear down sealant, scratch the surface, and damage the stone’s natural shine.
What to do:
Stick to pH-neutral granite cleaners or a mix of mild dish soap and warm water with a soft cloth.
4. Hot Pots and Pans
Granite is heat-resistant, but sudden and extreme temperature changes—known as thermal shock—can cause cracks or weaken the stone over time. Placing a hot pan directly on granite might not damage it right away, but repeated exposure increases the risk.
What to do:
Always use trivets or hot pads under pots, pans, and baking dishes, even if the exposure is brief.
5. Spilled Alcohol or Nail Polish Remover
Isopropyl alcohol, spirits, and acetone-based products can strip sealant and stain your granite, especially if left to sit. These substances are more common in bathrooms but can also show up during cleaning or entertaining.
What to do:
Wipe up spills right away and store chemicals securely in drawers or cabinets.
6. Rust-Prone Metal Containers
Metal cans or utensil holders may rust over time, especially in humid kitchens or bathrooms. The rust can transfer to your granite surface and leave behind stubborn orange or brown stains.
What to do:
Use plastic or rubber-bottomed organizers and avoid storing open metal containers directly on stone surfaces.
7. Unsealed Plant Pots
Houseplants are great for décor, but the moisture that seeps from unsealed pots can soak into granite and lead to stains, cracks, or mildew growth—especially if left for long periods.
What to do:
Use waterproof saucers or place plants on a protective tray to catch drips and condensation.
