my personal experience is that one can save a significant amount by using SimpleGreen as a primary cleaner for 5-10 minutes, then transitionning thru a ‘splash bath’ of old IPA, and a final wash in IPA.
I did a write up in here about 8 separate tests we ran on this. We have even set up an inexpensive method of re-claiming IPA, and as such, we’re able to recycle 75-80% of the IPA repeatedly. You can look in this forumn for post production cleaning…
i really would do that, rather than dumping hundreds into another cleaning liquid (which must then be handled as another potential chemical problem).
