Well, since I believe the ink is water soluble, I believe all you've proven with the wet cloth is that there is ink (dried or otherwise) within reach of the water in the cloth. 

Since you aren't getting a cartridge error, it sounds to me like the cartridges are plugged, or dried out. If they are actual HP cartridges, they should have an expiration date built into the electronics that prevent the printer from using them after a time. But that might not apply to 94/95s. The next logical test would be those carts in a different printer, or known working carts in that printer. So you are on the right track.
