I would like to know where I can find TSP. To clean a 60 yr. old oak floor that has been underplywood and Tile in the dining room for 40yrs. Its in pretty good shape. Has never been cleaned or polished. It does have some wear by the kitchen.I thought I could get it back to it's old glow, without restoring. I don't want to polyurethene it.....The rest of the house has been under carpet, so it is not as bad. Also I need some tips on a good wax. I appreciate it very much, and you will make my day.
