Ultrasonic cleaner for carbs?

Ultrasonic cleaner for the carb's internals/passages.....soda for the outside.

I thoroughly degrease them first if needed, then 1 x u/s clean, then a soda blast, then plain hot water for a few mins in the u/s cleaner to dissolve any errant soda.

Then re-bush throttle shaft bores on the primary side if needed.
