What is the best way to polish quartz countertops

Polishing your quartz countertop is one of the most critical steps in its overall maintenance. However, it’s still best that you clean your counter every day to prevent scratches and marks from forming in the first place.

The good news is that quartz is a strong and durable material that can endure scratches from most items you place on it. All it takes is a bit of care; you can expect your quartz countertop to last several years.

Using a clean microfiber cloth is the first step for polishing quartz surfaces. Never use abrasive pads since these can leave behind ugly streaks and other unwanted marks on your quartz counter.

You can then clean the quartz surface with dish soap and warm soapy water, and vinegar can also be used for more stubborn stains. Rinse off the surface and wipe off any soap residue and water with a clean, dry cloth.

How do you polish a damaged quartz countertop

It’s uncommon for professionally installed quartz countertops to sustain chips and other damage. But if you notice a chip, rough patch, or any other flaw on the smooth surface of your quartz counter, you don’t have to worry because you can quickly repair it with a bit of rough treatment.

If your quartz countertop has a rough spot, use a hand sander with 200-grit sandpaper to buff the area until it’s smooth again. Just make sure that you don’t grind too fast or too rigid. Doing so may result in a dip in the already rough spot that can further affect the overall appearance of the material.

You can also use a commercial product of the same color as your quartz countertop to polish it. You can easily find these products in most local hardware stores and online shops.

However, while it might seem like a good idea to use an additional sealant polish, it might soon result in further buildup and a generally duller surface appearance.

Once you’re done polishing your quartz countertop, you will instantly notice a difference in appearance. Although you don’t need to do this process daily, doing so as often as possible can help you reduce any damage or buildup on the surface of your quartz countertop.

It’s also recommended to keep a spray bottle of mild dish soap and water handy to wipe down your quartz countertop so you can clean them right away once you notice them getting dirtier.

Wipe off dark liquid spills as soon as possible to prevent stains. Use a cutting board and hot pads before you prepare food, and set down pans on your quartz countertop.
