What Can I Use to Clean My Granite Counters?

So you just got new granite countertops for your kitchen? Congratulations! Now what? How can you ensure they stay beautiful and shiny throughout the years? Regular cleaning and sealing: that’s the key.

First, you’ll need to gather the right supplies. Here’s what you will need:

  • Warm water
  • Dish soap
  • Sponge
  • Isopropyl alcohol
  • Spray bottle
  • Clean cloth or towel
  • Optional: baking soda, plastic wrap, razor blade, gloves

As one of the most durable countertop materials around today, granite resists wear and tear and daily use very well. It also resists scratches and heat. But due to its porous nature, it can absorb liquids. That means if you spill a liquid, such as water, wine or juice, it may stain. No worries. You just need to seal your granite countertops once a year to combat this.

Follow these steps for cleaning your granite counters.

Clean Off Your Counters

Clear your counters of all objects, including small appliances. Brush away any crumbs with a dry sponge.

Scrub the Surfaces

Steer clear of cleaning agents that are acidic, as granite countertops contain a sealant that ensures they stay shiny and resistant to stains. If you frequently use vinegar, glass cleaner or bleach, this can both weaken the sealant and dull the granite underneath. Just a bit of dish soap and warm water ought to do it. Work up a good lather using the sponge and start cleaning. Don’t use a sponge with an abrasive side so you don’t scratch the counters. Scrub in an “S” pattern for best results.

Work on Stubborn Stains

Sometimes all the scrubbing in the world doesn’t work. In this case, you’ll have to use a razor blade to get off the built-up gunk on the surface. Make sure the edge of the blade rests on the counter, and you shouldn’t experience any scratching. Once you have worked away the spot, clean it off with the sponge.

Don’t have a razor blade? You can make a paste consisting of baking soda and water. Gently work a soft cloth into the paste and remove the stain, then rinse. If it still won’t come off, apply paste to the area, covering it with plastic wrap and taping the edges down. Once the paste dries (could be a day or two), wipe it away with a soft cloth and rinse.

Disinfect the Counter

Add a 50/50 mix of isopropyl alcohol and water into a spray bottle. Spray on your counters and wait a few minutes. Wipe it all off in a back to front, “S” pattern motion with a clean towel.

Make it Shiny

For a little extra gloss, put a dash of cooking oil on a soft cloth and swipe it over your counters, followed by a gentle buffing.  

Apply Sealant

Once a year, apply an approved sealant to your granite countertops to protect your investment.
