If it looks like crystalised jello then it is residual glycerine IMO. Why are you using vinegar ? That has usually been suggested for breaking emulsions, but if you have a complete reaction then you shouldn't need vinegar in the wash. Prior to using vinegar try the quality wash test, found here: http://journeytoforever.org/biodiesel_vehicle.html#quality
