Ultrasonic cleaner for knives?

[AfterDark]

Does anyone use an ultrasonic cleaner to clean their knives without taking it apart? The knives in question are FRN and G10 handled spydercos. I want to get them spotlessly clean but don't want to damage them in the process.

I do, it works perfectly and without damaging your knives.

This is my cleaning recipe for folders:

1) Brush with old toothbrush and a mixture of hot water & some dishwashing liquid.
2) Rinse under hot running tap while constantly working the pivot
3) Shake out excess water and let dry a few minutes
4) Spray the whole knife with WD-40 and put in ziplock bag for at least 30 minutes.
5) Then place the knife in an ultrasonic cleaner filled with a mixture of hot water & some dishwashing liquid.
6) Turn the cleaner on and watch the knife "explode" in grey clouds of gunk & debris, loosened by the WD-40.
7) Rinse under hot tap while working the pivot
8) If necessary repeat steps 6 and 7
9) Shake out excess water and let dry completely
10) Oil pivot pin with Nano-Oil
