I also clean my injectors by soaking and shaking mildly using denatured alcohol. I have left the injectors soak over night with no seal deterioration but have also left soak over vacation and the seals will deteriorate with prolonged exposure.
Tip: change your alcohol frequently to prevent any residue build up which would ultimately affect the appearance of future repairs.
Pay it foward,
