*tip* tough carbon on case neck

Postby ShootnMathews » Thu May 22, 2014 8:34 pm

I've been prepping brass these past few days and thought I'd share a quick tip for getting that stubborn carbon off of case necks. When I first started loading I would just throw brass in my tumbler with corncob media for an hour or so. I noticed that when I took them out not all of the carbon would be removed from the neck but the rest of the case would be really clean. :think: Some use steel wool to clean it off but I don't like that. I found that I could take an ordinary paper towel from the kitchen and wet it with rubbing alcohol, and simply pinch it over the case neck and twist for 2-3 seconds. 90% of the carbon will come off on the paper towel and the remaining comes off in the hour tumble.....completely clean brass. :thumbup: The alcohol also evaporates very fast so the case is dry going into the tumbler. Just thought I'd share incase someone else likes their brass as clean as I do.

Rubbing Alcohol comes in various purities, I would bet the 70% would work better than the 50% stuff they sell. I wonder what would happen if you put some brass in a rock tumbler with Alcohol??

Not sure. That's an interesting idea. I've thought about trying some alcohol and brass in an ultrasonic cleaner.

Sounds like a quick clean way to d-carbonize the case neck prier to tumbling. I think if the tumbler was a sealed type the alcohol bath would work. What do you do with the waste alcohol as its full of chemicals an shouldn't be used again. That would be the only down side -- proper waste disposal. If you just wipe it on to clean with all the dirt id in the rag.

That's a good question Jerry. I guess I've never thought of rubbing alcohol as a chemical. Being country my grandparents used it for about every kind of skin injury. Is it really that bad? Ill have to do a little web searching. I can't imagine he carbon on the case would be harmful. I guess it could be though.

I was talking about washing them in a tumbler with alcohol. Although there not corrosive - there are leftover residues of spent primer and powder in the alcohol.

That's essentially what a sonic cleaner is. A tumbler that is not as agresive and just uses liquid instead of solid mediums.

Nice read Ben. Makes me want to buy an ultrasonic cleaner. Think I might.
