I spent 7 hours yesterday polishing out a shower. Cerium oxide for the glass and granite sides, compound for the travertine upper (soft sheen) and the floor was a hot mess.

Black marble, 4" tiles.
Efflorescence everywhere, lime buildup of 1/16" to 1/8" thick along edges and the grout where the shower heads dripped.
I scraped and scrubbed. Used Renew and a concrete brightener. Honed from 120-800, polished out and it looked lovely.

Until it dried completely. Then I could still see scratches, and significant lime still at the edges.

Gotta redo it. Now I am sad. My back hurts, my arms hurt, my neck hurts and my feelings are hurt. And I seem to weigh 700 pounds.

I hate doing my own showers in the house and they are made of plastic.

learned a key lesson, especially with black marble, before you transition out of the more aggressive diamonds , dry completely and check for stray scratches ....

I use a torch to dry the joints when doing black marble tiles of any size. Lippage can be a killer.

Ted all they really wanted was the lime encrustation removed. Being an idiot, I thought I could dissolve it and dove right in. Totally forgot how scratches fracture down into the stone.
I used a multitool to grind the edges on the second day, with acceptable results. Then repolished all the way up. The customers were delighted, even if I wasn't.
