Thank you Lobster for that, (cornish fisherman) ? To fill in a big gap
in my request, the idea is to clean timber, I make furniture from
scaffold boards, and what i would like is an effect similar to that
found with beach found timber. If sand blasting is rather messy is the
pressure itself enough to erode the wood, that is if it is high enough.


I think you might be better off with an air driven sand blaster. The
Karcher is very messy.
