The grey fuzzies are a semi solid structure forming out of silver particles being trapped on the surface tension of hydrogen bubbles that have grown too slowly to bubble off before being stabilized by the coating. As the bubble becomes coated, it becomes semi conductive and forms another slow bubble to become coated on top of itself..on and on in a never ending feedback loop. Wiping the fuzzies off breaks up the feedback loop, but it might start over again until water conductivity is high enough to draw the set current. Excess water current pressure is one factor that leads to the formation of these small bubbles. Another is too little current draw from ultra pure [highly resistive] water. Stirring too fast also runs a greater number of ions and particles past the electrode to be attracted by it, further exasperating the conditions of the loop. The slower you run the motor, the less stable it is. It may stall out at very slow speeds. So, shortening the stirrer allows for speeding up the motor without increasing stir rate. It doesn't take much to move that water and it should not move very fast at all. You can put a small bit of paper in the container to track the water currents. It should move sort of lazily around in an inverting spiral. One would think that running the stir rate really fast would blow the bubbles off, but apparently it only causes them to stick better on the surface that faces the direction of the water current and further compresses the bubble to keep it small. [The fuzzies grow into the direction of the water flow.] If you find yourself using ultra pure water, you can let the generator run without the stirrer until a localized area of conductivity [ion cloud] forms between the electrodes, then distribute that with the stirrer to bring the total conductivity up...or seed the water with a previous batch. Heating the water some also increases initial conductivity but heating too hot causes particles to collide with enough force that they can agglomerate right away.
On a good note, once the electrodes become pitted and rough from use, the hydrogen bubbles are formed in more localized an area centering on the pits [or, perhaps between them] and grow and bigger faster with fewer of them..and bubble off better. Formation of the grey fuzzies using pitted electrodes is rare. So, don't polish the electrodes, Just wipe them off.
