best way to clean injectors on car

I thought I saw a large aerosol type can that tapped into the fuel rail?

Only type I saw around here was intended for a proprietary kit. In other words (at the time and with that can) the problem was actually hooking the can to something, lol. I screwed up, this was on my 86 Ranger. I forgot about the regulator bypass and essentially when I hooked up the can, I dumped the contents into the tank via the regulator bypass tube lol.

Then I found this at the thrift store
