As soon as possible, remove soot and ash from dry items using a hand vac or nozzle attachment (not the brush!). A “dry cleaning” soot sponge (see Useful Supplies & Equipment) can then be used for further cleaning.
Wipe off ash. It’s very abrasive and will scratch the surface.
Turn objects or unfold textiles or paper before vacuuming them. The soot will disperse.
