Parts cleaner solution can wreck plastic shutter blades - learned this the hard way

Had a Nikon FE in the bath last week with what I thought was a standard parts cleaner. Guy from the camera club stopped by and saw me using it. He told me that stuff will eat the plastic shutter blades over time. I checked the bottle and sure enough it had ammonia. Switched to a water based cleaner and the blades are fine now. Anyone else run into this with modern shutter assemblies?

Plastic shutter blades" - I'm gonna call bull on that one. First off, like someone said, the FE has metal blades. But even if it didn't, how long does it take for parts cleaner to actually wreck anything? I've left lenses in ammonia based cleaners for a full day and they came out fine. People act like one wrong chemical will instantly destroy your gear. Most of these horror stories are from guys who let stuff soak for weeks or used industrial grade stripper. Water based cleaner is definitely safer but I bet your blades were never in danger from a short soak with standard parts cleaner.
