Break Cleaner - strange deposit

[stevie_d_64]

But you have a Stainless semi-auto right???

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.

I think he is right as well...

If you don't get the same result, try doing the mix on a neutral surface like glass...Try adhiering a light coating (layer) of the Ed's Red stuff on Pyrex, and let it set...Then spray or apply the Prestone to it...See if it beads up, flakes or crystalizes like it did on the guns...

Just a wild thought...

Is the Prestone's chlorinated? I remember reading somewhere you are supposed to use the non-chlorinated stuff. I forget the name of the stuff I buy at Walmart, but it's the cheapest they have and is non-chlorinated.

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