You should always wash your home siding by starting from the bottom and working your way upward. Applying your cleaning soap in this upward direction prevents ugly streaks from permanently staining your clean vinyl walls.

You can use a living utility for effective wall washing to maintain your home. You must keep the spray wand moving continuously to avoid concentrating the water pressure on a single spot. Holding the stream still for even a few seconds can warp plastic or puncture your expensive siding.

You need to angle the water spray downward so you do not blast moisture underneath the siding panels. Spraying upward forces water into your walls, which creates hidden mold problems inside your home structure.
