Cleaning and maintenance of granite countertops

Granite countertops are naturally resistant to stains, cracks, scratches, and cuts because of their naturally smooth and shiny surface. However, they are not foolproof. Granite countertops that have been used for a long time and have been exposed to daily kitchen use can be vulnerable to knife scratches, hot pan burns, and oil stains.

Common granite countertop stains

Granite countertops are naturally porous and can be prone to stains. Some of the common stain-producers are acidic substances like lemon juice, vinegar, and wine. Acidic substances can cause stains because they strip away the protective sealant of granite countertops. Another stain-producing substance is cooking oil. It seeps through the pores and crevices and stain the granite countertop from the inside out.

Common granite countertop scratches

Granite countertops are usually scratch resistant because of their shiny coat. However, they can still be prone to scratches caused by chopping or cutting directly on the surface or by dragging heavy kitchen equipment such as food processors and mixers across the surface.

How to care for your granite countertops

Despite the tough exterior of granite countertops, they are sensitive to stains and scratches. Granite countertops are expensive so they have to be properly maintained. Here are some ways on how to care for your granite countertop and maintain its shiny and polished surface.

• Seal granite countertops periodically. Granite countertops have already been presealed by manufacturers. Sealing is a process of closing the granite pores to make them resistant to any type of absorption that can lead to moisture buildup and stains. Sealing also gives granite countertops their noticeable shine. Professionals recommend having your granite countertop sealed once or twice a year, depending on how frequent you use it. Have it sealed more often if it has been exposed to acidic or oily substances.
• Clean granite countertops regularly. Your granite countertop has to be wiped down after each use. This is done not only for sanitation and hygienic purposes, but also to remove any leftover particles, debris, or substances that can scratch or stain it. The best cleaner that you can use is a simple solution of mild soap and water. Apply it on your granite countertop with a soft sponge and rub gently. Remember to rinse it with water to remove excess soap. Never use detergents, abrasive soaps, and rough sponges or scrubs to clean your granite countertop because they can cause scratches. Some manufacturers offer cleaning kits that come with the cleaning solutions and buffers. These kits can cost a bit more, but they can help maintain your granite countertop.
• Use a chopping board or other alternative surfaces during food preparation. Using a chopping board to prepare food can protect your granite countertop from the cuts and scratches. Also, do not drag kitchen equipment across your granite countertop to avoid scratching it. Most hardware stores sell protective pads that you can stick under the blender, food processors, and mixer. These pads do not only help you move around your appliances effortlessly – they also protect your granite countertop from scratches and abrasions.
