Onyx stone countertops are undeniably beautiful and elegant. They’re favoured for their unique beauty that easily becomes the focal point of any setting when paired with great lighting and other decorative elements.

Onyx itself is a translucent stone used in a wide range of applications such as flooring, backsplashes and countertops, in both bathrooms and kitchens. This diversity paired with its stunning appearance is what makes it a sought-after material among both designers and homeowners.

However, being a calcium-based stone, it requires proper maintenance to prevent damage and ensure it looks great and lasts. We want you to enjoy your onyx countertops for years to come, which is why we’ve come up with these tips to clean and care for it.

5 Simple Steps to Maintain Onyx Stone Countertops

Whether you’ve just bought an onyx stone countertop or are looking to purchase one, here are some tips on how to clean and care for yours.

  • Cleaning

Onyx countertops are made from silica-based soft stones that occur naturally. They need to be looked after well as their surface is vulnerable to acids and can be damaged by common household liquids like vinegar, coffee, lemon juice and red wine. Also, it’s best to avoid homemade cleaners, ordinary kitchen cleaners and window/glass cleaners as they generally cause more harm than good.

When choosing commercial cleaners, steer clear of abrasive ones as these can damage the appearance of your onyx countertop. Make sure you read the label first to avoid using something that might be too harsh or acidic. Instead, purchase ones with a neutral pH level.

You can use a soft microfibre cloth to clean your onyx countertop, but the best results are generally attained by using a soft tissue. Also, remember not to pour or spray the cleaner directly onto the onyx. Being porous in nature, it may absorb some of this liquid which can in turn affect its appearance.

  • Wiping Spills

Like all natural stones, onyx stone countertops are, as mentioned, porous, so it’s necessary to clean up spills when they happen rather than letting them sit. Blot the liquid with a paper towel as wiping will spread it. Letting acidic substances like lemon juice or wine remain can etch the countertop which will dull the stone.

  • Sealing

Although sealants don’t necessarily make your onyx stone countertop stain-proof, they slow the rate at which spills are absorbed and keep its durability and shine intact longer. However, it’s best to have this done professionally by your countertop provider as they will have the necessary materials and tools. If they don’t provide the service and you have to get a contractor, be careful. Onyx is a rare stone which is unlike sealing other natural stones such as granite and marble.

If you’re thinking about sealing it yourself, conduct thorough research to ensure you purchase the right product. Avoid ordinary stone sealers as these can harm the surface. Ask your countertop provider or installer for recommendations on suitable products.

Onyx countertops need to be sealed every one to three years to keep their durability and beauty intact. The frequency depends on the amount of abuse the countertop receives, the cleaners you use and the colour of the stone. (Lighter surfaces stain more easily than darker ones so need to be sealed more often.) Again, your countertop provider should be able to provide a resealing schedule to allow for the best results.

  • Polishing

Your onyx stone countertop is bound to develop tiny scratches, stains and other imperfections. To keep damage to a minimum, always use a cutting board in your kitchen. Remember, once damaged, it’s a lot harder to fix and can be costly in terms of money and time. By having a professional polish your countertop, you ensure it stays smooth and looks good longer.

Whether bathed in backlight or natural light, there are a few alternatives to onyx’s unique beauty. It is indeed a stunning natural stone option for kitchens and bathroom countertops. However, its care and maintenance can be tedious. If you’re thinking of buying an onyx countertop, you’ll need to invest in its upkeep. Your onyx countertop provider can recommend a maintenance program tailored to its usage and placement.
