The Cleaners I Tested
The [iSonic P4810 Commercial Ultrasonic Cleaner](https://www.amazon.com/s?k=iSonic+P4810+Commercial+Ultrasonic+Cleaner&tag=thetestedhub-20) was my top pick because the heater reached temperature in under eight minutes and the two liter tank fit my whole carburetor.

Quick answers
Yes. Warm water around 50 to 60 degrees Celsius breaks down oils faster. My grease-test parts cleaned in half the time with heat on.
You can, but a drop of dish soap or a proper jewelry concentrate triples the result. Plain tap water leaves a faint film.
