Your floor is fresh, new and looking great and you want to keep it that way. Finishes are 70% cure after 24 hours, 90% cure after 48 hours and 100 % cure after 72 hours. For that reason NO Shoes for a week. NO Rugs for those three days and furniture can be placed, NOT dragged, on this beautiful new surface. Be smart and place new felt on your movable furniture. The finish should be fully hardened after a month so until then treat it nicely
When cleaning, you'll be happiest with just plain water. Sometimes using 1 to 10 water diluted detergents to clean up grease or vinegar to disinfect. In my experience, any cleaner that brings shine to the finish is definitely does more harm than good. It is recommended that you vacuum your floor regularly but only after the first month of refinishing. Steamers are fine to use and so are swiffers.
The longevity of your floor depends on you. Those who use shoes will wear the finish quicker than those that don't. Keeping your floor always clean adds a lot to its life. When the floor finish is dulled, from years of use, a floor can be recoated. Another coat of finish can be applied which will bring back all the luster. It will remove scuffs, hide scratches and prevent wear through into the bare wood. The cost is a small fraction of the cost to refinish, is done in less than a day and adds several more years of life to the performance of your floor. Wood floors can only be refinished so many times so refinishing is not always the best answer. Stay on top of the wear and tear, add years of life and save money. In my book, that's the best way
