This may cause a smile. After the soaking in Acetone let the Acetone dry out of the wood. Next soak the wood in Vodka overnight of course do not use good quality Vodka though. As you would expect the Vodka soaks into the wood, then you allow the Vodka to dry off but only the Alcohol escapes the wood quickly leaving a small amount of water in the wood. You could use a low percentage industrial Alcohol but on this side of the pond they put all sorts in the stuff to make it smell and taste not so good to stop people drinking it, hence the Vodka.

The only lessons in my life I truly did learn from where the ones I paid for!
