I have lots of trim, ledges, and doors in my house that were covered with a dark stain and then polyurethaned. Looks great until the tiniest ding or scratch, at which point it turns white. Even minor vibrations and movement around door handles that were a little loose has left a white outline where it touches the door.
I can use Pledge™ or orange oil on these and they disappear perfectly…for about 1-2 weeks. Then the oil dries out (?) and the scratches are evident again.
Is there a way to fix these long-term (at least 12 months at a time), other than sanding/staining/repoly?
