What’s the best everyday cleaner for quartzite countertops in the bathroom?

Warm water and a microfiber cloth. That’s it for daily bathroom quartzite cleaning — toothpaste splatter and soap residue come right off. For hard water spots and mineral buildup around the faucet, add a few drops of dish soap or use a pH-neutral stone spray like StoneTech Daily Cleaner. Avoid bathroom cleaners with bleach or abrasives, since most aren’t formulated for natural stone. The shower is a different story though. If you have quartzite on a shower surround, squeegee after every use or you’ll fight hard water deposits weekly. The staining people see on bathroom quartzite is almost always from standing water, not the wrong product. Wipe it dry, keep it sealed, you’re good.
