Title: anybody ever ultra-sonic clean fuel injectors?
Post by: tb3 on May 24 2013, 11:15:38 AM
I love my ultrasonic cleaner.  specially for cleaning carbs and what-nots  :rock:
the other day I got to thinkin (uh-oh) I wonder if it would hurt my never been cleaned fuel injectors from my 233,000 mile buick lesabre?  :chin:
after all, the car is still running great, so why not dick with it?   :rofl:
 
If I use a water-based cleaner like simple-green, it shouldn't hurt the plastic or electric componet parts of the injector as long as I get them completely dry right away, correct?

I would be careful with the simple green. It does like to eat some plastics.
I have not tried it on injectors.

The one shop I know that cleans injectors does use an Ultra Sonic machine but no idea what the cleaning agent is that they use?

Yamaha carb cleaner doesn't harm plastics.   Pretty sure CLR won't either as it comes in a plastic jug.

did a little net searching. 
looks like to just remove the oring and drop them in whole probably won't hurt anything, but might be a crap-shoot.
best method is to dissasemble and do it the correct way. 
I've never took a injector apart.  probably more trouble than its worth if you don't have the right tools.

They pulse them while they clean them - how would you do that?
