I recently moved into a new-to-me home that was built in the 1950's with original hardwood still in place. I cleaned the floors extremely well and put the polish down in one room last night and this morning am very pleased with the results. It doesn't appear to have a milky appearance at all. I hope it doesn't happen over time, based off others reviews. But for now, I am pleased with the appearance and hope it stands against my small pups and their nails.
