Should I clean before filling out the list?

No. Record first, then clean, so the original condition is visible in your notes.

Who should read the finished list?

Share it with your inspector, electrician and any odor provider so each starts from the same observations rather than from memory.

Walk the room again after any drying, repairs or cleaning, and compare against the first set of photos.

No. Leave and follow the safety steps in the butane guide before continuing.

That is a good result. Keep the photos and notes anyway, since they document a clean baseline for later comparison.

Do these from the doorway when you can, and stop if anything feels unsafe.

Note whether the room is powered and whether any timers, ballasts or extension cords remain plugged in.
Look for scorched outlets, melted plugs or discolored cover plates.
Check for added subpanels, oversized breakers or unlabeled circuits.
Make a note of gas cans, cylinders, regulators or hoses.
If you smell gas or solvent, leave and contact the gas utility or emergency services.

Press softly on drywall at floor level and in upper corners for softness.
Look for rippling paint, bubbling, salt-like crust or dark spotting.
Check baseboards, door casings and any wood trim for swelling.
Look at the floor edges and carpet tack strips for staining or rust.
Photograph ceiling stains and note their position relative to the old light fixtures.
