My new log cabin sat without stain for 10 months and then the somewhat weathered and darkened logs were sprayed with a bleach/water mix and left to sit for a few hours. The logs were looking very nice and clean and white and then, just a few hours after bleaching the cabin was stained with a clear linseed oil based product. The logs now have black spots and splotches. How can I get rid of the black splotches if it has just been stained. Need help much because I want the logs to be light and
