... story, here's what i do know. They are in bad shape,dull, with extremely cloudy film all over,scratched,ect. When the house was purchased, was told they were imported maple and to clean only with water/vinegar mixture.Maple? I really don't know.The house was built in 2000. The finish was kind of glossy looking and shiny, so i was convinced it was sealed with poly, after researching some and thinking about it, i thought no, it must be a wax and my method of cleaning over the past 4 years has slowly caused the wax to wear down and that's why its dull. After further inspection I can see that some of the scratches have gone all the way thru the surface finish and are super shiny underneath,also i can scratch those places with my fingernail and it just flakes right off in tiny pieces. But who the heck uses shellac anymore. So, I am seriously stumped!! I don't know what it is, hopefully someone who has knowledge in this field can help me out?? Thanks, cameron
