If your house is stucco buy a backpack sprayer and spray it down that way. Depending on how dirty it is youre going to want to be somewhere around 2-4% sh. Its going you take you forever buy like the other guy said above down streaming probably won’t touch it. Porous substrates need a stronger mix. Honestly you’d be fine just rinsing with a garden hose. There’s nothing professional about doing it that way but it’ll get the job and you can experiment with different % of sh to get an idea of what you’ll need to do in the future.
I wouldnt plan on cleaning your driveway with a rental unless you can rent a surface cleaner with it…and the correct nozzles. In my opinion its not really safe to hit residential concrete with anything over 2500 psi. I learned that the hard way. Alot of resi concrete is really soft amd only rated for 2000-3000 psi but unless you can talk to the guy who poured it theres almost no way to know.
