Important Notice: This Common Ingredient Could Damage Your Countertops

Natural stone surfaces like quartz, granite, and marble add elegance to any kitchen or bathroom. Not only are they stunning, but they’re also incredibly easy to maintain. Their durability means they can last for many years with the right care. Though staining is rare, it’s still possible under certain conditions.

When it comes time to clean, there’s an important caution to consider. A popular natural cleaner found in many households should never be used on stone countertops or other natural stone surfaces—lemon.

Why Lemon Juice Can Harm Stone Surfaces

Lemons are packed with acidity, which gives them their sour taste and makes them perfect for enhancing drinks, sauces, or salad dressings. As a cleaning agent, lemon juice is antibacterial, acts as a natural bleach, and leaves behind a refreshing citrus scent.

The acid in lemon juice can damage your stone countertops by breaking down the protective sealant, if one is present, and eventually harming the stone itself. Without a sealant, the acid can quickly seep into the porous surface, causing stains. Other acidic products like vinegar or strong bathtub cleaners can also have the same effect, so it's best to avoid them on stone surfaces, warns The Stone Collection, a major stone countertop retailer.

It’s not just cleaning products to watch out for—acidic foods should also be kept off your countertops. While a quick spill of lemon juice or acidic wine won't cause lasting harm if cleaned immediately, it's best not to place cut lemons or limes directly on the surface.

There are cleaning products made specifically for natural stone, and these are your safest bet for preserving your countertops. Be cautious with other household cleaners, such as Dawn Powerwash, which works wonders on grease but may contain acids that could damage your stone surfaces.

When cleaning natural stone, it's best to avoid homemade cleaning solutions that might contain hidden acidic ingredients. Instead, opt for a cleaner specifically designed for stone surfaces to maintain and protect the elegance of your countertops.
