Technetters,

In January, Brian Ellis raised some excellent points about the hazards of using nPB, or 1-Bromopropane. With the release of the OSHA/NIOSH Hazard Alert on nPB July 31, 2013, the pressure is on to stop using this stuff. We use the trade name Ensolv. While we slowly convert to aqueous batch cleaning, our need for spot cleaning on the bench will remain, as we are more like an R&D shop. We are using rosin core solder and RMA flux applied topically. The techs love Ensolv, and it does work great. Does anyone have a recommendation for a replacement of Ensolv? I have seen the specs of 3M Novec engineered fluid, maybe 71DA is a good choice?

Thanks in advance for your advice.

Howard A. Watson
