Osmo oil is very good but what we use is boiled linseed oil mixed with 40% pure turpentine : spill plenty of oil on then half hour later wipe off , do this three times , job done and do not use wax. What are the benefits : it is time tested for 100`s of years and it is not so expensive but the most important benefit is that you can communicate with your customer ,you give them a pot of your "special oil" to esily apply if they wish to brighten the finish and over the years it gives the BEST finish and when their pot of oil runs out they come back to us for a refil and then we quite often get another commission to make another piece of furniture for them .
