I know oxalic acid is used to lighten wood but will it work on this?
I have spruce guitar top which I jointed, cut to shape, inlaid a rosette and sanded to near final thickness a couple of years ago. I was then distracted so it was put on a shelf. It was partly covered by a sheet of cardboard for protection but the uncovered bit has darkened, I assume by being exposed to daylight. Before I splash the acid on it, does anybody know if it would remove this type of discolouration?
