Daryl, I have used raw linseed oil to clean stocks and checkering on older stocks with original oil finishes. I believe that method came to me via this board and Mr Petrov. Worked well on a 1910 Mauser sporter stock that also had blooms of white spotting (mold?) on its buttstock.
Yep. Water stains also when caught in a rain. I keep touting Timberluxe, especially the No. 2 formula that’s a little thinner, but once you use it, you’ll throw rocks at boiled or raw linseed oil. It’s not cheap, but it it is good. Cheerio.
