I'm not sure, but I'll check tonight. I didn't have time to experiment last night, but perhaps tonight.

Jim:
That sure sounds like my situation, even down to the description of the deposits.

I do, but this is happening on my blue guns as well.

I'm going to experiment a little tonight by spraying some metal has Ed's Red on it, some that is bear metal and some that has #9. I think SJRTX's comment about the ingredients is on point, since it has happened only with Prestone Break Cleaner. Maybe their secret sauce is the problem.

That's another good point. I'm going to spray it on some other metal and see what happens.

Tom:
That's a good thought. I'll try #9, just as a test. Ed's Red works too good to go back to #9, so I guess I'll have to stay away from Prestone Break Cleaner. I would like find out what this is. Next time I think I'll try to get a digital photo of it and post it.

Nope, they're tough little buggers!

I like your idea for another seminar. Marc and I talked about having either quarterly seminars, or perhaps three times a year. I think the reloading one will be next, then this is an excellent one. I know a very good pistolsmith that might be willing to do a seminar for us. I'll talk to him and let everyone know. Keep the seminary ideas coming.

Back to the break cleaner. The specs occur before any towel is used on the gun. After the cleaning, the gun still has a good bit of Ed's Red on it, so I spray it with the break cleaner and then use my compressor to blow it dry. That's when the specs appear, although they will also appear if I let it dry naturally.

The specs are small, white, hard flakes about 2/3 the size of a flake of Unique powder.

I've been using various brands of break cleaner to aid in gun cleaning for years. I buy the cheapest stuff I can find by the case; usually under $3/can. I've been running an experiment with Ed's Red for months now, but that was covered in another post, so I won't repeat it here.

As part of the cleaning process, I use the break cleaner at the beginning and end of the process. Currently, I'm using Prestone Break Cleaner and it works fine. However, after all of the cleaning is done, I spray everything with break cleaner to remove the Ed's Red. Unlike all other brands I've used, the Prestone is leaving small white specs on the gun. They don't wipe off with a towel, but a plastic straw or plastic pic removes them easily.

Has anyone seen this with Prestone or any other brand? Any ideas what it is?

Thanks,
Chas.
