Whats the most common question customers ask after you finish restoring their marble floor ??

"How do I care for my beautiful new floor ??" I would love to have a bottle of neutral cleaner to leave behind with my company name on it. Does anyone have any info about a company who offers such a service. Obviously there would be an order minimum to make it worthwhile for the printer. I have no problem with this as the cost would be figured into the price of the job. Just need to find someone who will do it......
