We have Della Terra Quartz -Shiitake on our kitchen counters. We love the look and color. After a short time we had water marks developing and marring the look. After trying a variety of cleaning/polishing products and a lot of frustration, we contacted a rep at Arizona Tile. (Denver) A representative responded the next day and made an appointment to visit our home within the week. She brought a product called Counter Kleen by Miracle. Using this with a Scotch Brite scouring pad, and rubbing the marks started to lift off. She also recommended starting with some Soft Scrub gently using the scouring pad first. Then following up with the Counter Kleen. This second process works amazingly well!
I wish we’d known about this cleaning process 2 years ago when the Quartz was installed, but we appreciate the response from Arizona Tile.
