Use a timing light hooked to the coil wire to see the actual spray cone and droplet configuration.

The stroboscopic effect will make the spray pattern a 'Stop Action' so you can get a good look at it.
If you want to slow the flashes down, connect to one of the spark plug wires...
Cleaning is easy depending on what type of injectors you have.
Some can be removed and manually cleaned.
Others have to be 'Pressure Cleaned' in place with a special solvent.
Still others can't be practically cleaned and have to be replaced...
Howell uses an early type of GM TBI that can be disassembled and serviced.
Personally, I'd take them apart, clean them with a healthy solvent, paying particular attention to deposits around the nose, and reassemble with fresh seals.
Remember, don't use a wire brush or anything that can scratch the injector or the injector body!
Nylon brush and strong solvent will do the trick.
