On the subject of why some people report using Danish Oil on veneered doors without incident... (me included) On being told recently by a supplier that I should DEFINTELY not use Danish oil on their veneered doors, I told them that I bought 7 of the same doors from them 8 years ago, and they still look great, no sign of the glues being compromised by the oil. So I asked a carpenter friend why he thought my doors were okay. He said, manufacturers have been steadily reducing the thickness of veneer on doors over the last few years. When I bought mine, he says the veneer may have been say 3mm thick, and as I'd applied the oil with a cloth, it wouldn't soak in enough to affect the glue. These days, he says, the veneer on many doors is only 1mm deep, and therefore it is now a lot more likely that Danish Oil will penetrate the veneer and reach the glues.
