Carbon burn removal ?

[Revofan]

Recently picked up a new to me open gun 

had an old Cmore serendipity sight 

took it off to upgrade sighting system and there’s a Burn stain on the top of slide does anyone know how I can get this off without ruining hard chrome finish ?

hoppes 9 should remove most of it.  I use it around my brl holes and works great.

We don't have open guns but this stuff works for carbon crud

But is it safe to use on hard chrome finish ?

[MikeyScuba]

I found this in the FAQ section.

 

Q: Is the C4 Carbon Remover safe for use on chrome lined barrels?

A: Yes, the C4 Carbon Remover can be safely used on chrome lined barrels, chromoly steel barrels, stainless steel barrels and any other commonly used barrel steel.

fine steel wool?  And just rub the entire slide to get the same finish throughout.  Or scotch pad.

 

Very light bead blast?  I personally would bead blast it.

I would try lacquer thinner.  Won't hurt anything.

A Mr. Clean Magic Eraser might do the trick, or a scotchbrite pad. Just try in an inconspicuous location first. 

 

I've also used Slip200 Carbon Killer on the bolt tail of a chrome AR Bolt to help clean it up.

Try some CLR Cleaner. I have used it on my open guns to clean the carbon residue off the comp and it worked with no adverse effect on the chrome. Also cleans the smoke off your red dot really well.

I did try mineral spirits to no avail 

I’ll try some of these other ideas before ordering boartech product I’ll leave that as a last resort 

 

thanks all

Try some Flitz past.

Walmart carburetor cleaner. $2/can.  Spray it on the slide, and a shop rag, rub with vigor.  If it's persistent, you can use a poly gun brush.  If you REALLY need to, you can use a bronze brush.

I’ve used flitz to get the carbon off my hard chromed Galil gas piston without any damage to the finish

[Revofan]

Will it change the finish 

make it looked polished ?

[ltdmstr]

Yeah, I'd be careful with any kind of polish.  You don't want a bright spot that doesn't match the rest of the slide.  I'd say brake cleaner and brass/bronze brush (lightly) are the best advice so far.

[EEH]

I’ve cleaned revolver’s with it without any problems

[shred]

WD-40 worked as well as anything.  Put it on a cloth and rub.  Spray some more, rub some more.

Try one of those lead remover cloths. I find it removes the carbon buildup arond the muzzle and cylinders of my stainless revolvers.

[MikeyScuba]

I like those lead cloths for my revo too, but they do have a super fine polishing compound in them.  My 929 has gotten a little polished inside the frame.

yes, Flitz or other metal polishes will do that, so will lead remover patches.

 

Fast evaporating solvents like brake cleaner and laquer thinner are not very good for removing carbon. WD-40 and other oily solvents like kerosene, diesel, etc do a much better job, but you'll need to put some elbow grease into it as well. You could try some fine steel wool, or copper or brass scrubbing pad (i.e. Chore Boy pads). 

 

Chrome is pretty hard and durable, you don't need to worry about damaging it with most chemicals, just avoid abrasives like polishing paste, scotchbrite pads, or sand paper since all of those will change the finish.
