Defoamer in shot coolant?

[Hal A Looyah]

I am using eTrim 206 circulating in a parts cleaner. It is getting pretty foamy. I thought about adding some antifreeze to cut the foam. Any ideas?

Is defoamer not compatible?

we would get that happening in our grinding machines and the cheapest thing we found that worked was a small amount of kerosene.
