Do You Own an Oceana Glass Sink
and is it in your bathroom? Mine has dulled/etched at the bottom around the drain like maybe where water doesn't drain out completely. It's a Crystal Reflections color so it's not noticeable to anyone other than me unless I point it out. But I'm considering put a cobalt copper color in my husband's renovated bathroom. It's a dark copper brown. Thinking if it does it again, it's going to show up worse on the darker color.
