Update. Been now told jet washing is a no-no, so now holding off for
quotes to have the area properly cleaned (probably 'class H' vacuumed).

get a chair ready....
why not just rent a class H vacuum???

You don't want high pressure water as it blows the dust everywhere

just lots of low pressure water.

Though a standard home pressure washer can be used successfully to fog
or mist (dampen) large areas effectively.....

(Mine also has an additive pipe so one could add a detergent/whatever
if that was wanted/necessary)
