I have redwood plank fencing, the usual 1x6 stuff popular here where I live in SoCal. One section of fence is four years old and is now greying quite a bit because it wasn't treated properly with preservative. What can I use to revitalize the wood and get some of the original color back? I know there are chemicals and such but I'm afraid of killing the grass that borders the fence.
