Use a shop vac .=)

monammonium phosphate powder blue - not toxic, but a little irritating, and it will definitely corrode electrical equipment and you do not clean brush well. Try to take place in powder form as much as possible with a shovel and a brush, then (as suggested before) use a shop-vac.
