What ultrasonic cleaning solution is better for IDI injectors

[dbrannon79]

Guys, I just ordered a small ultrasonic cleaner to try and clean up a hand full of 6.5 injectors I have, most are gummed up and have varnish on them. I did try them on an engine I have on a stand by pulling the IP line up enough to just test it out of the engine. some popped and some didn't and were completely stopped up.

I want to pull them all apart, inspect, clean, and test them. I will be making a new thread on this soon, but for now I would like some input on what solution would be good to use in the machine to remove the varnish and carbon deposits along with any other debris they might have before testing.

My first thoughts were a few bottles of the pour in type berryman's chem tool, this stuff seems to devolve carbon on contact but is extremely flammable.
other ideas were a can of carb dip solution. or should I keep to using a water base solution?

Here is the unit I ordered.

I opted for the mechanical over the digital button type timer and temp, I'm not a fan of chineese electronics failing, I figured if this unit has a true timer in it, if the ultrasonic portion fails after amazon's warranty is out, I can replace that part without fear of the timer or reostat on the heating element electronics failing.

I would make sure whatever you use is ok with the temperature you'll be using

This is the best carbon remover I've ever used, water clean up... Use this as the liquid in the ultrasonic machine https://www.autozone.com/fuel-and-engine-cleaners-additives/carburetor-and-throttle-body-cleaner/p/berryman-chem-dip-carburetor-and-parts-cleaner-96oz/139313_0_0?spps.s=1010&cmpid=LIA:US:EN:AD:NL:1000000ER:19488533498&CATARGETID=120054150001289410&CADevice=m&gad_source=1&gclid=Cj0KCQiAx9q6BhCDARIsACwUxu4ueI2TqmJWyZEHq3vFSQda1A08dcWe833NkRtajkwielUjVtElFhkaAodOEALw_wcB&gclsrc=aw.ds&=undefined&new_store_set=true.

No it's not flammable...

The ultrasonic cleaner arrived today! it's rather small, but will work for my needs. filled it with tap water to test, powered it on and dipped a small piece of aluminum foil in the water. within a few seconds I started to see the foil form pin holes within.

tried the heat and set it to 85 degrees. I did not expect it to be very accurate since it's chineese origin, in about 20 minutes it heat tap water to about 130 degrees by just setting the dial to 85. the dial goes all the way up to 175 degrees so I know not to go that high!

just as a test I poured some water base degreaser I use in the mop bucket and gathered some loose change I had in the cup holder of the truck along with a semi-rusty flat washer, dropped them into the basket and will run it for a 15 minute cycle as a test.

Test results.
