Visited a prospect at the end of last week - a small construction company with a textured ceramic floor, white on the high spots and a kind of artistic dark brown textured layer a bit lower. The office manager thought her current janitorial service was neglecting the floor, leaving a bit of dirt in the textured areas. I carry a small test kit in the trunk (I provide janitorial service in Phoenix AZ), so I brought in a bit of degreaser and a bit of an alkaline all-purpose cleaner, to see how much dirt I could easily remove. I squirted down a small puddle of each, let them set for a half minute (minimal dwell time, but I was in a hurry) and gave them a quick scrub with a stiff brush. Surprise! All the dark brown came off; the tile was supposed to be pure white after all. A quick scrub should take care of the rest.
Interesting what a dustmop followed by a string wet-mop will leave behind. Had the janitor been vacuuming rather than dustmopping, using a microfiber wet-mop rather than a string mop, and had any knowledge of janitorial supplies and equipment at all, he could have kept his client...
