Quick word about Murphy oil Soap,
A good friend I just spoke with has over 40 years in finishing/refinishing all types of hard wood flooring.
When looking in to refinishing hard wood floors he makes a point in asking the client how they clean their floor.
Murphys is a red flag to him. Apparently it leaves a penetrating oil residue finish in the floors that causes him to sand deeper than needed. He has to pull off enough material to get past the sealed build up left by the Murphy. After a couple nightmare refinishes he found the culprit to be Murphys, he was having problems with his sanding screens gumming up, his stain and or clear finish having uneven and limited penetration and adhesion problems also.
Any Murphys left in the existing grain will react with the new finish, limiting penetration, softening it and giving a dull appearance. This is irreversible unless enough of the wood is sanded down past this 'Barrier coat'.

In his words:
"On some floors the longtime use of Murphys would require so much material to be removed that it can be cheaper to remove the old flooring and start over, unless they can live with 1/4" hardwood floors."
He also said if in doubt try searching on line for problems refinishing over Murphy oil.

I have no reason to doubt a 40+ year veteran.
