After far to long with any attention, I just cleaned my cedar log siding with a bleach based cleaner (nothing else would even make a dint in the filth) and it is now back to its original color with no grey or mildew so I am ready to treat it. I am thinking of using CWF-UV clear. It claims to be a penetrating stain that protects from sun, water, and mildew. Any thoughts on this product or other recomended products? Thanks!
