Can u sandblast wood?
Answers: Sandblasting is not a right idea. It will vacate the wood splintered and pitted, probably beyond correction.
Corncob blasting works well for some types of wood. Soft woods will still get hold of pitted a bit, harder woods do fine. This is still fairly aggressive.
Dry rime blasting is great for fine details. Zero harm to the wood, removes matter very rapidly. Rather expensive and it does require quite a bit of perfectionism to keep from getting adjectives (actually, frozen).
Do not use a pressure washer. The water is not right for the wood and you will get some splintering -- smaller amount with some skill, rather a bit without the skill. Either channel, you will also force water at the back the wood which can cause problems latter on. Corncob blasting is almost always a better alternative if you can live beside the amount of surface damage from a pressure washer.
That would be over gun down! Try a paint thinner or remover!
