just cleaned my new 870P for the first time (got questions)...

[Chris17404]

Hi guys,

I just cleaning my new 870P for the first time (just out of the box). It has the blued finish and Remington says there is NO cosmoline on the gun at all. From what I have read about cosmoline, I definitely do not think my gun has it.

I have a few questions...

1. To clean the barrel, I drenched inside and out with RemOil and let it sit about 30 minutes. Then I used a brass bore brush with cotton patch to clean the bore. The first few times through the bore, the patch was dark brown. Then I went though about 6 or 7 new patches until the patch came out clean. Once I was ready to assemble the gun again, I put a new patch with more RemOil on it through the bore. It came out dark brown again. Why? I used one more clean patch so that I'd leave a thin coat of oil inside the bore. So... why did the patch with RemOil on it coem out brown again if the bore was clean?

2. When re-assembling the gun, I put a few drops of RemOil on the action bars, the ejector spring, and blot assembly. Would you recommend oiling any other parts?

3. When cleaning the trigger assembly, I did exactly what the owner's manual said: sprayed RemOil on it and let it sit for 15 minutes, then spraryed more on to clean it, then shook of the excess oil. This still left quite a bit on there. But I figure this is an important part of keep well oiled. Should I have wiped it down a little more before re-assembly?

4. The last step was wiping down all metal exterior parts with the silicone cloth. When I did this, again, the silicone cloth had brown stuff on it. Does this mean the exterior of the gun was still dirty? Or is this normal?

Thanks!

Chris, what do you mean, please, by this: "Remington says there is NO cosmoline on the gun at all." ?

Documents on their web site (cited in another thread) claim the 870P comes shipped coated in Cosmoline & should be cleaned before shooting.

Did you speak to or get an email from them stating otherwise?

You're probably getting "rust" off the new blue job.

Remember. bluing is a controlled form of rust, and when a blue job is still new, it's said to be "green", or not fully cured.
Wipe the finish with an oily cloth, and you'll get brown stains.

Many people who do high-quality refinishing will soak a "green" or newly blued gun in warm oil for a week or so.
Every day, they'll wipe the surface gently with a clean patch soaked in oil, and this removes uncured bluing.
This looks like rusty brown stains on the patch.

After a week of this, the blue job is cured, and has a much higher gloss.

Many of the new Lubes like Rem-Oil and CLP Breakfree are very effective rust fighters, and will lift the brown uncured bluing off the gun.
This is probably what you're seeing.

Even old guns will shed a little rusty stains when the gun is coated with one of these new lubes.

As for the bore, I'm sure Remington does put something inside to prevent rust during shipping.

Probably, the Rem-Oil just didn't remove all of it.

Re-clean the bore with the brush and patches, but this time use a standard bore solvent.
This should remove any remaining preservative.

DFW, forgive my stupid question. When I think of 'soaking', I think of immersing it.

So by 'soaking', do you mean simply wiping it down and letting it sit, or literally bathing it in oil, as in a pan?

I suspect the former, but just to be clear...

Nematocyst-870,

Yes, I did e-mail Remington and they said they no longer use cosmoline on any of their guns. Various people on other forums have received the same response from Remington on this issue that I did. So, I think it's safe to assume it's true. But... I do agree that they make it confusing by having that statement about cosmoline on their website.

I've seen it done both ways.
One method a re-finisher I knew used to give a Python-quality blue job, was to actually immerse the parts in a glass pan of warm oil for a week.
He actually had a warmer set-up to keep the oil warm.
Once or twice a day he'd take the parts out and very gently wipe them down with a soaked patch.

The difference between a job done this way, and one not, was startling if you could compare them side by side.

I've also seen freshly done "green" bluing coated with oil, then wiped down once or twice a day for a week.
This too brings up a better gloss.

With the modern cleaner-type solvent lubes like CLP Breakfree, the aggressive cleaning and lubing action will lift brown stains off even older gun, especially ones that haven't had a heavy coat of protective lube on them.

To the point of the original question here, I think Chris17404's stain problem is just a fresh blue job still aging, and the Rem-Oil lifting off the stains, and second, most gun manufacturer's don't use the cleanest protective lubes on factory-new guns.

MOST new guns will have brown colored, dirty looking protective lube on them.

That warm oil and rub down twice a day works real good on my wife too, she spent a week at a spa and boy did she shine like never before.

LOL. Wow. I've evolved from jellyfish to worm. Hey, I'm making progress.

Thanks for the clarification, Fariswheel. Very helpful.
