In the time it took to get my spruce frame dried-in the timbers grayed heavily. I found that that a 1 part bleach to 8 parts water mix lightly sprayed on with a garden sprayer brings them back nicely. Since I've got a lot of stickered material stored inside rinsing the frame presents more chore than I'd like to take on if I don't have to. My test area after several days seems to be fine: no white salt residue and no odor of any kind. I'll be lightly sanding and applying tung oil.
Any experience with the bleach process and input regarding whether it should be rinsed or no? I understand the chemical process and what's left behind is basically table salt.
Thanks
