I have used all sorts over the years.
My dad had some stuff called shine seal. It dried up and I binned it because I didn't think k it was any better than solvol autosol.
Having said that if I remember he used to dip the finished blank in to a liquid, can't remember if it was suagar soap..
or caustic soda..
I will have to dig his book out again to see what he used to do.. but that won't be for a while as the shed is going through a bit of a change around and sort out..
