Default Cleaning my own injectors

I found a place about 2 hours from where I live that can clean and balance injectors. The problem is that I need the injectors sooner than they can get them done. For now since I have them out I just want to clean them reseal them and reinstall them myself until they become less busy. What can I use to clean them? Varsol? dip them in injector cleaner? Can the entire injector be submersed? These are NA injectors.

Thanks

you can buy your own injector cleaner from snap on and a few other tool companies.

You might want to check out Travis' kits from Rennbay:

I don't know if that is EXACTLY what you are looking for, but the tutorial covers cleaning as well....

I made up an injector cleaning setup by taking an injector lead off of a scraped wiring harness (yeah, I know that doesn't help you much, right?) and wiring it to a momentary on type switch in series with a 9v battery lead. I got a cheap garden type pump sprayer and some fuel line that fits snuggly over the end of the injector. I fill the sprayer with injector cleaner, pump it up until I have a little bit of pressure on it, and then hit the switch for about 1-1.5 seconds at a time. You don't want to hold it open too long or you run the risk of burning the injector out. This will clean your injectors up nicely, and then just reseal them with a Rennbay kit, and put them back on the car. Don't forget to lube the seals and pintel caps with a bit of ATF first, before installing them.

Take the hat and seals off of the outlet side, get a two or three foot section of fuel proof hose that will fit over the bare end. Clamp this onto the bare end. Fill the hose with solvent and hit it with some 100 psi shop air. This will back flush the injector blowing any small particals out the back and also purging the inlet screen of crud. Depending on the solvent you use you can let the injector set then come back and hit it again to get any varnish out. Ultrasonic cleaner is suggested for subborn varnish.
