Oh my GWAD, there are 47 doors in this house (including closet doors). And all of them have two sides. The Husband Guys says, "Aren't you glad we don't have CUBE doors?". That would have been even more evil...
They're regular wooden panel doors with a white finish, so there are some rectangular patterns carved into it. Some are French doors, so they have glass panelling. We cleaned all the doors in pairs. One person scrubbed it with a Mr. Clean Magic Eraser to loosen the dirt and crud. The second person mops up the wet gunk with a sponge.
Christ, I didn't know doors could get that disgusting. For something that just kinda hangs there, mostly doing nothing, maybe swings back and forth being opened and closed, they get really gross.
But, it will be on the market soon. Woohoo! =D
