if you are a noob and don’t know what equipment can clean which surface, here’s a quick guide. It’s not meant to be exhaustive, and it’s up for debate, but it’s a pretty solid start and I feel really amazing about it.
How do you define softwashing? (this can be like soap wars)
12 volt = softwash
pressure washer downstreaming = softwash
or both? I would say both 12volt for roofs, downstream everything else
I’d be beyond careful using pressure on Stucco or Dryvit. In fact don’t, just soft wash it.
