Bidding a job with a bunch of travertine floors. Did one with a strong alkaline cleaner and my extractor. Didn't get it out og the crevices. Thought on the next one I would hit ti with bleach after to at least try to get rid of the dark color of what remains in the crevices. Pictured is a completed tile, and a before.  Any ideas?
