Still experimenting with it. Used 40/40% vinegar-hydrogen peroxide 20% H2O then soak in water with 2 table spoons of baking soda and table spoon dawn dish soap per You Tube. Also 40/60% water/ Simple Green, both seem to work the same. It helps to place the objects you want to clean in a plastic container with the cleaning solution, then place that in warm water inside the cleaner. Cuts down on amount of cleaning solution and makes clean up easier.
I would use caution with the HF cleaner as the heating element will not turn off automatically, this is something you need to keep a eye on. Also if you use it more than 3 times consistently with the heat on it will shut down. The water gets hot so run it twice with the heat on then turn off the heat function and run only in the ultra sonic mode. After what I thought were clean parts then placing them in the cleaner and seeing the results of the dirty solution it appears to me to work well. As to the longevity of the HF cleaner, your guess is good as mine.
