How do you clean your house’s face?

We have a Queen Anne Victorian and live in a pretty temperate climate where it doesn’t typically rain in the summer.

Our house gets SO DIRTY on the outside throughout the year even with rain- covered in a fine grit of dirt. On top of that we have orb weaver spiders that create super strong webs that also get dirty. How do I clean my house?

I don’t want to clean it so bad I have to repaint it sooner because I’ve stressed the paint and it’s a very tall house so power washing or scrubbing seem impractical.

Our windows are original so spraying the outside of the house with a hose doesn’t seem like the best idea either unless we want an indoor pool.

Any recommendations?
