Surface rust

[J-Man]

Any good oils in this regard that resist HEAT well too? I always smoke my barrel clean every shoot!

Is there anyway to remove rust from hard chrome? It seems like it's underneath the plating in the form of black specks.

Sounds like bad pre-chome plate prep'ing .. inadequate pickling maybe and/or nickel stage. Doubt much you can do therapeutically.

Not sure but ... an application of cola might just lightly phosphate treat it if permeable enough ... to arrest things. Not put that to test tho.

Cola Phosphate treatment??

Bill .. there is usually enough phosphate (phosphoric acid) in most colas to achieve conversion/stabilization on light steel rusting. You can use proprietory brands of phosphating treatments but colas will often be enough. Pepsi seems to do it anyways! Try it on a rusty nail.

Did you mean, "don't put that to the test?" Or is it safe to try it?

What I mean is ... try it! It is totally safe if you want to try and phosphate some light rust .... tho probably slower than using a proprietory formulation.

It should be possible after some exposure to the cola - then rinsing off with water .. to see a color change .. the brown turns very much darker which usually indicates it has been converted. De-greasing is needed BTW before any phosphating, as the solution is water based.

A gentle rub with finest wire wool should not produce any brown rust surface color or powder - if it does then buff gently again with fine wire wool and re-treat, with another rinse to follow ... and dry thoroughly of course.

It's not brown; it's black.

Oh sorry - I was forgetting your original point re black specks, hard chrome etc.

To be honest .. without seeing the offending item .... it's hard to know exactly what is there. Black can also suggest an iron sulfide ... what happens I wonder if you scrape a black spot with a toothpick ... just to disturb its surface a bit ..... will it still be black or not.

I have no hard chrome on any of my guns so - nothing to compare with at all.

Dang it - you gotta make those pics a smidgeon smaller .. this ol' phart is stuck on dial up!

Well - I see the specks but still hard to tell what they comprize. I think we need someone else to chip in here who has hard chrome and similar effect. This appears to be occurring just under edge of grip panels .. so possibly linked with moisture/sweat. Sorry not more help.

Yeah, I'm almost positive that it's from sweat. I have some forming on the dust cover as well. I wipe the gun very often now. The whole left side is prone to rust because of my sweat. Houston is too damn hot! I'll try to get some clearer pics later. I would love to be able to get these spots out.
