Rubbing alcohol won’t damage most countertops, and you can mix it with water to create a disinfecting spray to keep your kitchen clean. It’s safer than using bleach on countertops, which can stain and cause discoloration. Be careful with rubbing alcohol when it comes to lacquered or varnished surfaces, though.

With proper maintenance, concrete countertops can last for decades, with a life expectancy of 50 years or more. At a minimum, they should last 20 years before major issues arise. Their longevity depends on the quality of materials, proper installation, and consistent care. Because concrete is porous, it is prone to cracking and staining. Regular maintenance, including resealing, waxing, and repairing any chips or cracks, is essential to preserve its lifespan.

You don’t need a cutting board. In fact, cutting is the original purpose of butcher block countertops. That said, wood is porous and can harbor germs. You’ll need to clean your countertop thoroughly after use. Knives can also scratch the surface. This adds to the patina of the wood, but not everyone likes the look—in which case, you may want to use a cutting board.

The frequency for sealing marble countertops depends on several factors, including the quality and color of the stone, the type of sealant used, and the amount of traffic the surface receives. Marble has a porous surface that requires sealing to maintain its shine and resist scratches. As a general rule, you should seal countertops at least once a year. However, for heavily used surfaces, like those in a busy kitchen or family bathroom, you may need to reseal them every three to six months. Conversely, countertops in a rarely used guest bathroom might only need resealing every few years.
