It isn't cost effective. the additives for fuel injection cleaning are more for minor cleaning that a high quality gas such as mobil would prevent anyway. It won't hurt it. As opposed to that , I would recommend a professional fuel injection cleaning that entails disabling the fuel pump and running the engine directly off of the cleaner. Another good service to perform is an air induction service to remove carbon.
and on the piston head will get dry from the heat of combustion. When this carbon dries it will act like a sponge, sucking the fuel into it as it enters the combustion chamber. Anyways, try this as good maintenance:

I like to use castle hydroblast. You spray it into a vacuum line such as the brake booster line if nothing else is accessible. Full spray for 3 minutes, stall the engine with it or have someone kill it while your spraying. Let it set for a few hours then take for a short drive in low gear, revving the rpms to help break it up. First use Castle cleansrite to clean the throttle bore. Try to get the throttle plates scrubbed good with a brush, while your spraying. Use a rag to wipe the carbon out between brushings. Seafoam is another good product, but smokes a lot.
IF you can't find Castle, here is my rep's email:
