Our log home will need restained soon. I hear cob blasting damages the wood. Would you recommend cob blasting or pressure wash the old stain. If it fails the water test, do I need to remove the stain first?

DO NOT power wash to remove old finish. It will drive the water too deep into the wood fiber it will never dry out properly. Corn cob blasting works great, but it needs to be Osborne brushed after. The blasting does not damage the wood if done correctly. It only needs to be stripped if it is faded badly or is peeling. If the color is still good and the adhesion is good everywhere, then just a LIGHT wash with Log Wash and a maintenance coat of the SAME stain is needed.
