Midew on exterior

[MBB]

Hi, Looking to get ideas on the best way to remove midew from the exterior of the house without damaging paint?

You can spray a mixture of bleach and soap with a garden sprayer or you can spray bleach plus Jomax with a bleach tolerant bug sprayer. If you do the latter, be sure to get the bleach/Jomax concentration exactly right and wash thoroughly with water after the specified time period, particularly if you have darker paint. Otherwise, you'll end up with bleached streaks across the entire surface. If done right, bleach with Jomax will literally melt the thickest mildew away in minutes. But you must be careful. Also avoid breathing fumes. Use a respirator.

Alternatively, and something I myself have not investigated, you can use the enzyme formulations that supposedly eat mildew away and can be left on the surface. This is something I would very much like to find out about, so if someone else has used the enzyme products, please comment.
