Cleaning a quartz countertop is something that you will need to stay on top of to avoid any sort of stain build-up or bacteria. To clean the flooring so that we don not damage the quartz surface, it is important to use suitable products and techniques. Mild dish soap diluted with water is an appropriate option for daily cleaning. Wipe the surface with a soft cloth or a sponge without an abrasive side. Do not use chemicals, like bleach or ammonia, which can dull the finish.
