Today I took out a bunch of oak furniture that I built years ago for a new coat of oil finish. Getting it out in the sunlight I was surprised by how yellow it looks now (its about 9 years old). Almost looks like someone applied Golden Oak stain which I do not like so much.
The wood is quartersawn oak with several coats of oil applied originally and a recent coat of Tried and True Varnish Oil.
Would I have any luck trying to fume it now? My impression is that oil finish penetrates the wood so it might not let the ammonia work. On the other hand, ammonia is pretty potent stuff so it might penetrate the through the oil. Yes, I could test a scrap but I thought I'd post this question before I go shopping for ammonia, protective gear, etc.
Thanks in advance,
