I buy a bottle of house wash from homedepot.
I reuse the bottle.
It's basically Clorox. The bottle siphons/meters the Clorox. I refill the bottle with Clorox and some tsp about a table spoon or so.
Is it safe for the plants? Thanks.
I've never had an issue with the plants, but mine are spaced away from the siding. Some I'm sure gets on them. I'm careful not to spray directly on them.
Some times if I think a lot got on them I rinse them with the hose.
Is your home single or 2 story?
I did have to get on my 6ft a ladder to spray from the bottle , to the top of the siding on my 2 story.
My new pressure washer has a tank , with a down steam 1/15 mix, so I can mix Clorox and tsp in that and apply with the extension wand and black nozzle.
