We recently had the metal roof on our home painted. The paint crew looked at the green lichen growing on our foundation bricks. When I commented that it was time to get a pressure washer in, they said, “No. Go get some Spray and Walk Away.”
After some more questions (Where can we get this? Sherwin Williams) we decided to give it a go.
Basically, it is a solution you dilute 1:5 in a regular garden sprayer, wet down the growth and walk away! Works on mold, lichen, algae, etc and can be used on roofs, painted surfaces, bricks, vinyl siding, decks.
This is one home maintenance product that lives up to expectations. The green algae on the deck and painted rails was gone in a mater of days. The moss/lichen on the brickwork two weeks later is just a grey haze.
For cleaning home exteriors without the hazards of pressure washing, Spray and Walk Away gets the job done!
