And, again, we can get some data from existing electric propulsion use as well from neutral exhaust to see how quickly it clears the system.

The particles trapped in the Earth's field is on the order of single
digit kilograms and the residence time is around 6 months.  In half a
year the reaction mass expended by a power satellite project is around
a million tons or 10^9 kg.  Swamping the existing particles by a
billion fold seems likely to do something.
