Nice one Neil, I have argued many times at The "pops the grain" so does cooking oil, 3 in 1, wd40 or duck oil.
The only benefit I have ever found is, if wiped with the grain it does clean the dust out but so does a dry brush or a wet rag.
It's primary use was and still is for cricket bats and I never did see any benefit in slimeing that up either.
Best I could find at short notice Neil.
