It depends on the type of floor (wood, stone, concrete, tile), how it is finished, and how soiled it is. Most commercial floor cleaners have a high pH plus additives. I'd suggest using a detergent less aggressive, and perhaps diluting it more to the point where bubbles begin to form but don't foam. If it's an historic floor a conservation surfactant/soap is probably a better choice, with a product like Vulpex or Triton. If it's a relatively modern floor with no historic or artistic furnishings or collections directly on the floor(e.g.furniture or sculptures), something like Murphy's is acceptable if it's diluted down. You also want to clean with a dryer damp mop when collections are present or nearby so as to minimize the amount of moisture that will be evaporating in the room if you have rH sensitive collections present. Of course you should look into strategies to minimize the need to clean - from applying wax and buffing to isolate dirt from the floor to using area carpets and floor coverings for high traffic areas. Also consider what people walk on before they come in the door. I've seen several historic buildings with sandy soil paths outside where the 200 year old wood door sills and floors near the entrances have literally been sanded down by visitors where the original wood has to be replaced. So always be proactive and consider ways of protecting original surfaces from what comes in on people's shoes. Cheers!
