At 60k you shouldnt have to pull the injectors and clean them. Unless you are experiencing driveability or poor mileage problems, I would buy a can of Toyota injector cleaner and add it to the tank with only a couple of gallons left in the tank so the cleaner is more concentrated. This stuff works but costs $10 a can. I just put in one can a year and I've had no problems.
