If you have natural stone countertops, or are considering them for the future, etching is something to be aware of in order to maintain the surfaces properly.
So what is etching?
Natural stones, including marble, granite and quartzite, contain calcium carbonate, which dissolves when it comes into contact with acid and creates etching. Acidic spills that are cleaned up within 45 seconds are typically ok, but anything longer can create etching and stains.
How to avoid etching?
Wipe up spills quickly, especially ones containing acidic qualities, and be sure your countertops are sealed. Protect your investment!
