I not questioning the claim that peanut butter or petroleum jelly might remove white water blush stains from furniture finishes but don't understand how they might function chemically.
I thought that such watermarks were the result of microscopic globs of water suspended in the finish & removing them involves "sucking the water out" by means of a dessicant (like alcohol or diatomaceous earth.)
How then would petroleum jelly or peanut butter work? Aren't they both already saturated with water?
