I am not familiar with your specific firearm, but when we take our M16's to the armory and they get dropped in the solvent tank, the stocks come out really grey/white stained (kinda like a bleach stain i guess). What I have found that works to get the original color back is to put CLP on a toothbrush and scrub it into the stock, untill your color returns. Then wipe it down real good. We only have CLP at the armory, so Im not sure if another lube would work the same way. I hope this helps.
