Anyone use TPS to clean their house siding?
TPS is tri sodium phosphate.
Someone recently told me to use TPS and Bleach, in equal parts. Mix with warm water and apply with a sprayer, and I shouldn't need to use a scrub brush at all.
I asked about the dogs, and the environment. He said follow up with hosing down the grass where it all drops from the house. Or put a sprinkler on for an hour or 2, to water it down.
I wonder if I can use it without the bleach?
My white house gets a lot of green gunk on the back. Seems this is pollen from my maple trees. Once it settles, then all the rain, and this green gunk develops. That is what I need to remove.
Any thoughts appreciated!
