Coffee bags

[BJung]

Does anyone roast coffee? Will the coffee remnants in a coffee bag corrode my brass?

 

[horsemen61]

No clue I’d toss some not super great brass in one and wait a week or two and see what happens

I think I'd just wash the bags and forget about it.

I doubt that there would be any corrosion, I use the tall plastic Folger cans from Costco. And some small amounts of grounds remain. Never seen any adverse effects.

Coffee contains phosphoric acid. Often used in metal cleaning processes. It cant really do anything until hydrated. I use coffee bags for same purpose. Works fine.

Yep, me too. All my clean brass is in old Folger's or Kirkland cans/tubs. No trouble here. Now, leaving a tub uncovered while the evaporative cooler is running is a different story-- had to do some re-tumbling that time.

Your post made me curious. It seems that walnut shells also has several acids in them.

Operative word is DRIED walnut shell. lot of precursors of acids are inert until they hydrate. PH cannot be measured without water.

I know in the morning I'm inert until I have my coffee beans.

I'm concerned about dampness left in the bag.

Amen!

I would think a small amount of talcum powder shook around in the bag should pick up any moisture.

I'm another that uses the plastic Folgers Coffee cans. But I do rinse them out. Never noticed any corrosion. The shelves in my loading room resemble the coffee isle in Krogers!

That's why God invented dryers....

Regular or decaf?

If you use decaf, you'll get reduced loads!

Some reloaders have even gone as far as picking up a box of crushed walnut shells at Harbor Freight and a bottle of Nu Finish car polish. Rumor is you put a cap full of Nu Finish in your tumbler with the walnut shells and let it run 3-4 hours. I know it sounds radical but I've heard it works. FYI, run the walnut shells and Nu Finish for 20-30 mins before you add the brass. If you forget this step the first time you won't the second.

 

[BJung]

Are you trying to say that the Nu Finish will protect the brass from corroding. I would then worry about the Nu Finish in my tumbler because I use that for powder coating my cast bullets.

I heard of a guy once that had 2 tumblers.

Inconceivable!

 

[Mk-211]

Only 2?

Heck, I use one of these for 50 BMG alone! * pro tip, remove the paddles.

I've heard there are people that have more than 1 gun as well. I've never seen it myself.
