If you’ve spent time scouring the internet, you’ll have seen people recommend vinegar and others tell you to steer clear of it. It’s not a straightforward answer to a seemingly simple question. Of course, it’s your choice to use whatever you think works best for your countertops. In general, you shouldn’t use vinegar for regular cleaning. If you do choose to do so, dilute it before applying it. The reason it’s discouraged is that vinegar’s pH levels can actually damage your countertops over time: it can cause clouding, yellowing, or dullness in the quartz finish.
What you typically want is something very mild as a cleaning agent on your countertops daily. We recommend a few drops of dish soap in water and a microfiber towel to clean. Make sure you wipe off any excess moisture afterward. Additionally, don’t let spills or food sit on the counter any longer than you have to. The one circumstance that some people recommend a vinegar solution is for restoring a shine to the countertops. They recommend a 25% water and 75% vinegar solution to apply a small amount and shine with a clean microfiber towel. In general, this should be a last resort and tested on an inconspicuous section of the counter first.
