Cleaning Wood Doors before Polyurethane

I have a number of wood doors that were stained but never polyurethaned. I would like to polyurethane the doors but would like to clean them, sand them, etc. to do things right. One of the doors is in a bathroom and has been subjected to moisture and is stained as a result of this.

Any suggestions on the best way to go about cleaning these doors before polyurethaning.

A light sanding (make sure not to go through the stain) should suffice on a door in good shape. The one with the water mark will likely have to be stripped and restained first.

If any of the doors were around a kitchen or other situation that might have left a residue of grease or oil wipe them down with mineral spirits/paint thinner to remove it.

It is never a good idea to leave stained woodwork without poly/varnish. You may have trouble removing the dirt/grime without affecting the stain. Be carefull with sand paper as it is easy to cut into the stain. Paint thinner may or may not bother the stain. You'll also want to be sure any wax or cleaners are removed before sealing the doors.

The only way to remove water stains is to completely sand thru them although you may be able to disguise it enough to get by with less work.
