10 Substances That Will Stain Your Granite Countertops

We all know that granite is durable, and when properly sealed and cared for, resistant to just about any stain. But there’s no such thing as a surface that is completely impervious to staining. Even granite can be marred if spills are left to sit or if surfaces are not adequately sealed. That’s why it’s important to use the proper stone surface cleaning and sealing products on all your granite countertops!

Granite isn’t a particularly porous stone, but, like all natural stone surfaces, it does let liquid in if it isn’t properly sealed. To tell if it’s time to re-seal your granite countertops, perform a safe and simple water test. Sprinkle a few drops of water on your countertop. If the water beads up, then your seal is probably going strong. If the water soaks in and darkens your granite, then it’s time to re-seal. Sealing is vital, as it creates a barrier of protection around your natural stone.

Other types of stone are differently affected by potentially staining liquids, so different kinds of countertops may require different care, or be particularly susceptible to certain types of stains. Whatever kind of countertop you have, though, your best bet to prevent stains is to clean up spills immediately, and always use the right stone surface cleaning and sealing products for your countertop.

What are some of the substances that can leave a permanent stain in your beautiful granite countertop if not properly cleaned up right away? Watch out for red wine rings if you leave your glass on the countertop, or a leaking carton of fresh blueberries. Some other culprits include coffee, tomato juice, grape juice, mustard, citrus products, toothpaste, and anything with chemicals. When water seeps into your granite countertop, it leaves a dark spot that evaporates in a few minutes and returns to normal. But substances like cooking oils that don’t evaporate can cause permanent stains if they’re allowed to soak into the stone.

The best thing to do to protect your granite countertops from stains is to clean up spills as soon as they happen. Even a completely sealed granite countertop can stain if a spill is left to sit for long enough. And, of course, more lightly colored granite is more likely to show stains than darker colors, so if you have a white or other pale-colored granite countertop, it’s important to be extra vigilant.
