GREAT FOR QUARTZ
Had been using the cleaner/sealant for years recommended by the tile company that installed the kitchen countertops.  Needed to reorder and the former came as a kit with a daily cleaner.  A bit skeptical, but find the daily cleaner is great, and do not have to use the sealer as much.  Also, found the daily cleaner does a super job on stainless steel as well.  No build up and removes finger prints and occasional water drips from fridge.
