Bleach works well for cleaning up gray-wood, better on some species than others, but particularly well on EWP.
Regular old household bleach – Dilute it one to one in a garden sprayer, apply, then follow with a hosing – This fades the gray nicely, but leaves the wood dull looking – Follow with a treatment of Oxalic acid, commonly sold in powdered form in hardware’s as Wood bleach, this brings out some nice coloring, and is something I routinely do to Pine Frames after a cleanup planning and before applying finish.
I’ve also experimented in applying lightly tinted finish over light graying on newly hewn timber for a faux time driven oxidated look, even going to the trouble to roll sticks for even graying.
Never blasted anything, but I’d think Pine is not a likely candidate.
Tim – I have a deep aversion to sanding. Don’t own a sander, and if I buy sandpaper it’s by the sheet
