I'm looking for plant safe products to wash the exterior of my house.
I wash the exterior of my house every Spring and use off-the-shelf products. The more gentle of the two (deck wash) does a decent job on the Hardiplank siding; I reserve the more powerful product (Chomp Gutter Cleaner) for the black stains on the vinyl gutter. Although I use plenty of water and elbow grease, I'm concerned that both solutions are a bit too strong to use around my shrubs.
I welcome any recommendations on alternative / safe products that are effective.
