Pros: works well, chlorine and phosphate free
I tried this surface scrub on my sink, which had become a pretty dingy yellow color. It did a really nice job cleaning and whitening the sink without too much effort on my part. I just spread a bit in the sink, scrubbed for a few seconds, repeated once, and it came out looking pretty good. As soon as she saw it, my wife - who often doesn't notice when I've cleaned something - immediately remarked 'wow, the sink looks really good!'. So clearly the scrub did a nice job. My wife also tried it on our dingy countertops with equal success.
It doesn't use chlorine or phosphates, and mostly relies on oxygen bleach which Mrs. Meyers claims is "naturally safe". I don't know much about oxygen bleach, but it does a good job!
