ADS Aviator
Flush
Do you have experience with an ultra-sonic? Have you seen this before? I could use an opinion as to the cause or if anything is to be done?
See pic below. The inlay of the chip on the left is visibly grey compared to the chip on the right. Both chips went through the US at approx the same time (within a few minutes of each other).
US- Vevor 6L & Salad Spinner
Cleaner - Red Devil TSP (1 tablespoon per 4 cups of water)
Water - Distilled
Temp - 38-41C
Time - 45sec
I've cleaned many hundreds of Paris $1s & $5s and never had this happen. I usually run $1s for 1min @ 41-43C & $5s for 30sec @ 36-38C. Not exposed to sunlight. Thoughts?
