I feel a little embarrassed asking this, but I have a WC customer that also wants the organics cleaned off her brick window sills. A few are second story, can I just hit them with 4% and let rain do the rest or will pressure be needed? I’m not comfortable getting on a ladder wanding off brick.
If you hit them a couple times with 4-5%, just normal garden hose pressure will rinse it off. For you, it’s probably easiest to hit them first thing when you get there, get your WC stuff all set up, hit them one more time, then clean those windows last and just spray it off with a garden hose before you wash them. I would not leave for time and rain to finish the job. They are paying to have nice clean windows, I’m sure they don’t want to look out of them and see white chunks stuff on the sills.
Scruba dubba doo. Get a bucket of 50/50 with some elemenator and scrub them clean. Make sure you charge for having to bust out the muscles. Price goes up as soon as i touch a scrub brush and step on a ladder.

I do what Tampa said. I keep a couple palm-size stiff bristle brushes for things like this.

Perfect, thanks guys. Got up there and soaked with 4%, let sit for a while, scrubbed with stiff brush and everything just rinsed right off.
