Other than bleach, what can be used to remove mildew and algae from siding? I use bleach regularly; however, there are times when I feel the bleach isn't strong enough. What is recommended to lift dirt from siding? Sometimes, I notice a gray stain left on vinyl overhang which I am unable to remove? Any advice on better chemicals to use or as to what this stain is and how to remove it?
Thanks!
