Vacuum smells like farts after using it for protein powder spill

Made the mistake of picking up half a container's worth of protein powder that my son spilled on the floor with our indoor carpet vacuum cleaner (and by "my son," I mean me). Now the vacuum smells awful when its turned on. I was thinking of sucking up a can of ajax or some other type of powder cleaner and let it sit in the guts of the vacuum for a couple of days. Is that a terrible idea? Anyone have another suggestion?



Thanks in advance!
