A common problem that I see customers running into is mineral deposits on their countertops. This is a common result of ‘hard water’ or high mineral content in their water. To get to the root of the problem, you should have a professional check out your water filtration system. However, what we are discussion here is the residue that is left behind on your countertop after the water dries
WHAT TO DO:
If you have granite countertops, this is an easy fix. All you need to do is get a flat razor blade and scrape the residue off from the top. Hold the blade at a 45 deg. angle and gently scrape at the residue. It should come right off like powder. THIS WILL NOT HARM YOUR COUNTEROP. I am often met with surprise when I do this, but it has to do with the mohs hardness scale. 1 (talc) is the softest, 10 (diamond) is the hardest.On this scale, a razor blade is 5.1. Granite, which is made up of mostly feldspar and quartz, runs anywhere from 6-7. It’s just science!
Now, if you have marble, it is a whole different ballgame. Marble is extremely soft, ranging anywhere from 2-5 on the hardness scale. A razor blade WILL scratch your top in this case. So what you can do is use a solution of ammonia and water to gently scrub it away with a bristle brush. DO NOT USE any acid-based solutions like vinegar or lime juice. These can etch your marble (a whole other topic I will write about in the future). If the ammonia and water solution doesn’t work, then call your local professional. When working with marble, it is better to err on the side of caution!
