Ghost marks???

[Tiger Wolf]

I have P95 and I was cleaning it and noticed some fingerprints within the bluing on the front of the slide. Is it from the factory or did I possibly do it. There is no rust and or pits and it looks smudged. I thought the finish should be harder than that. Just by chance how long would it take for wet or oily fingerprints to affect the bluing? It is less than 1 year old and I always wipe it down the same day used or within a couple days. I would take pictures but, it is only visible at certain light angles. I have a similar mark under the decocker lever that I positively did not do, kind of looks like a wide scratch that was covered by an extra liquid blue. The marks are lighter than the normal blue and would normally be noticed and do not seem to have damaged the metal. The fingerprints look smudged. What chemicals would dissolve blue? Could it be my fingerprints yes, but I already take great care to prevent rust and scratches. I use cotton gloves when cleaning and a full flap holster when in service. By the way I bought this NIB and it had only left the factory a couple months earlier and never left Prescott, it’s a Davidson gun.

I would guess it the prints of the last person to touch your slide before it went to the blueing tank.
Some of the foaming bore cleaners are about the only thing that I know of that would ruin blueing, well I think some brake cleaners will but I am not sure.

Have you used any of those?

No,just normal Hoppes, molly lube, and WD40.

Without photos it's hard to say what's going on with your pistol's finish (might still be hard with photos), but if you are using the WD40 as your final wipe down, stop and change to something formulated for that; WD is not a good choice for protecting finishes on blued guns.

What is wrong with WD-40?

What is wrong with WD-40?

The worst thing about it to me is it attracts dust like a maganet which wicks off the lubricant.
In a dust free world its good stuff for rust protection, we use it at work in the clean room and it works great. Outside that room and you can tell where its used.
I use CLP or Remoil.

WD-40 attracts dust and it repels oils and causes your lubricants to be much less effective. It's generally a bad thing for a gun.
