Hello. I have MSI Calacatta Verona quartz counters. After a few years of just using water to clean, I used Bar Keeps Friend soft scrub on a water ring stain. Im now noticing this permanent ring that looks brighter. Im not sure if I should try BK Friend all over or cut my losses. Its only noticeable in the sunlight. i called the installer and they recommended a 3/1 spray which def cleaned and shined but it didn’t help with this mark. Any advice? Thank you!
