Doug, well done on the link, on viewing the video, we need at all times to be mindful of just we have, how we use such and store them and the cloth, it's not a case of even binning them, I'll think about drying mine as I do over the rungs of the ladder across the shop roof trusses.
I have from over time, but not used BLO, Linseed, Turps etc.. it's mainly Danish I use, if it were in it's original can I'd read up on it, something to think about should we decant, have that something not sure what or may even mix and make that special finishes, safe maybe some, but then just what cocktail we may have could be a time bomb.. the man said: 9 out of 10.. lets not be 1 ..
All have a safe 2013.
