Refinished hardwoods not holding varathane
We just recently refinished all the hardwood floors in our house. We followed all the necessary steps, sanding, washing, etc. Applied one coat of varathane, waited 24 hours, did a light sanding (to remove dust particles) then applied another coat of varathane. Then waited again for 48 hours before putting furniture on them. The floors looked beautiful for the first 12-14 days, now over time it appears as thou the varathane is wearing off of the floor. The high traffic areas seem as thou they have no varathane left on them, but low traffic areas are still shiny. Any suggests, thoughts, ideas?
Also, what is the best to use for cleaning them. I've heard vinegar and water, Murphys' Oil soap? I've tried both, and neither one seem to give me a nice shine.
