My log home exterior is extremely dirty and has many black stains and black stained drip markings. I’m told it’s from dirt sticking to pollen. I live in a heavy pine tree area with lots of pollen. I’ve tried washing with TSP, no bleach though, but it didn’t help much at all. I need to know how to clean these logs without stripping or damaging them. They are very, very dirty and sticky.Thanks
