Mildew on Gutters, Siding

March 1st, 2010 by admin Leave a reply »

I have mildew growing on the gutters and vinyl siding on the side of the house that doesn’t get much sun. I noticed on your website that you suggested the use of Jomax, bleach and water. Is this recommended for gutters?

Answer:

Mildew or mold will always grow on exterior surfaces that don’t see much sun – at least in our Wisconsin climate. I would definitely wash with a Jomax solution, bleach and water. Follow the label instructions. Often you can just spray the solution on the stains with a garden sprayer and then rinse them off. This is an inexpensive cleaning solution that “activates” the laundry bleach.

I’m not sure how the Jomax chemical works, but I know that it works great on vinyl, aluminum siding, and aluminum gutters. It also works on any hard surface with mold or mildew. I found that it does not harm plant materials, but I would wet them down before and rinse them after you use Jomax.
