Problems with hard water area

We live in a hard water area, over the past months we have noticed water marks around a very large area of our quartz work surface, no matter how hard I cleaned it was difficult to clean until of course I tried your Solid surface cleaner and polish. Now my Kitchen gleams with pride and have just phoned the suppliers of our worktops and the kitchen firm we purchased our kitchen from to recommend your products. I wish I had bought shares in your company as I am advertising your products with great joy and pride!! Well done
