As a chem dry tech with 6 plus years in the business i had all the knowledge of anything floor care related from carpet fibers to tile cleaning. Chem dry also does stone polishing in Utah, something i did not know a lot about. As me and Gary where called out to a stone polishing in Utah job we both where at a learning experience with stone polishing. We where there about 6 hours and learned a lot in that time. What works and what doesn’t. I had my regrets about any results because of the stone. But we did achieve results. I think we learned a lot and now can do stone polishing better with our added experience and knowledge.
