Just a few moments ago I went thru this exact process. picked up any intact leaves on the floor because they'll possibly plug your shop vac hose up.
Shop vac'd , looked for bleach and had none, so I loaded up the atomist with 29% h2o2 (diluted of course, I'm cleaning a room not removing paint/skin/whatever)and doused every-fucking-thing.
Got in there on my hands and knees and mopped that shit up with a old towel. loaded up the atomist with Riptide(pyrethrin based insecticide , went heavy since the rooms empty. this flushes spiders and shit from hiding too) blasted the room with the Riptide.
Took 2 mg xan.
Did some mods and changes.
Took a smoke break.
about to get back up at it even though they call for a 12 hour re-entry time on pyrethirns , safe for mammals I might add.
I'll be moving plants in tonight more than likely.
