I have a home that was sided with 3×10 pine half log siding 7 years ago. I am seeing alot of logs that are turning black and have tried various things to clean, bleach, and even sand out the black, but there is so much of it and nothing seems to be working. Can you recommend a product or a suggestion of what the problem might be. I am in Northern Wisconsin if you could recommend a contractor.
