I’m thinking of “automating” a bit the IPA cleaning with a “poor man’s” solution
I found this video for a DIY magnetic stirrer. The solution seems to be quite cheap.
On the other hand, I found out some people use a ~3 Liter ultrasonic cleaner with IPA. Those are also cheap on eBay.
So the question is… which gives a cleaner part for the time and the buck?
I have to point out that I’m not comfortable with the non-sealed lid of the typical ultrasonic cleaner if full of IPA. I’m not concerned about it catching fire, it is just the fumes/smell of the Alcohol that will evaporate all the time are not nice to breathe.
