Marble, Dry-Treat, & Porcelin OH MY!!!

We have been cleaning and sealing one of our Distributor's showrooms (we are an installation company also) this past week. Floor is a unpolished/unfinished Italian Porcelin with Marble/Slate/Granite inserts here and there. We use our porty with a Turbo Hybrid going over with stripper on the first coat then StoneTech Restore on the porcelin (not the polished stones) afterwords. Floor looked great in the process of cleaning after the first day so we sealed with Dry-Treat stainproof. Come back the next day you can still see the marks and some dirt on the porcelin. Owner is 'ok' with the job knows it is much cleaner but this is a BRAND NEW install 2 months old. We have had problems with unfinished porcelin's before and their marks but nothing like this. My question is what has anyone used to remove the Dry-Treat or get some shoe/dirt marks off from the stone once sealed? Secondly, we used Klenzall on the polished stones with the turbo and they are noticing alot of scratches in the marbles. In the light you can see them looking almost like a circular motion. We have used this tool many times before on these surfaces with no problems but owner is sure it is from us. We are trying to make the best of this situation using honing powders and going to Dia-Glow with some success but we are scared to grind down with diamonds these areas because we cannot seem to get the factory finish back up if we do. Sorry about the novel but any comments or help will be much appreciated.

P.S Al, I'm awaiting your response, please!
