Just throwing this out there for you guys. We have an oxygenated cleaner that we designate as an all-purpose, but safe for all natural stone. We weren't expecting it to perform the way it has, but it's been good to us. I have been using it for soap scum and it's been working well. 10-15 minute dwell time and scrub with rags. Maybe not ideal for professional use, but great for homeowners or when you're in a pinch. Guaranteed safe for any natural stone. Non toxic, biodegradable.
Here's the rag I used on the porcelain shower.
