It's such a beautiful sink! We sealed it with the bottle of sealer that came with it, but we are getting annoyed by the little stains that have already popped up on the sides and bottom of the sink. We don't want to scrub it too hard but they are there after only been a few weeks of use. Just annoying because we were told that quartz is supposed to be one of the most durable sinks available. I would love suggestions.
