For the life of me I cannot understand how our old cupboard doors seem permanently wet, almost soaked through. We had them dipped and stripped in 2000 and ever since they have had wet patches on them come hot, dry summer or winter. I have a dehumidifier in the room constantly which has made the room completely damp free (old house) but alas the water is still in the wood. I do not understand why this should happen as it doesn't make sense and defies the laws of physics.
