I have all hardwood floors that were original to the house and I don't use polish for cleaning. I use vinegar and water for the most part.
I think there is more information out now and some products are safer but I was chemically poisoned when I worked in the Art Department at a University in the mid nineties and my life changed forever. Fortunately I realized what it was and what caused it, the system also knew and I was allowed to work from home but never received any monetary compensation. I was pretty much house bound for 3 years because of it and I still have to avoid some places and certain aisles in the grocery stores. But as a result they moved those classes to a different building that had better ventilation and enforced the EPA rules. In the past the printmaking instructor had relabeled or taken home the really dangerous chemicals. So at least I like to think some lives were saved. All the people who worked for many years in the building I was in have died from or had cancer or Parkinson disease. I have been lucky so far that the sensitives issues seem to have got me out in time.
I think the public has become more aware but I cringe when I see the latest air freshener made especially for dogs that claims it is safe. Well, the aerosol product that disperses it isn't. So please, read labels and if you have unexplained headaches, loose your voice or have respiratory or other issues check labels! Use no or low VOC paint especially inside. Avoid fragrances when possible including perfume. Rug cleaners and yard sprays particularly can be extremely toxic especially for dogs and children. My basic cleaning products are vinegar and water in spray bottles, vinegar in washing machine rinse water instead of fabric softeners and baking soda to clean sinks, stove and other places one would use a powered cleaner. All are also inexpensive.
