Removing one-shot aerosol residue from cases

[Lefty Trigger]

Hornady one shot case lube. I follow directions on the can. Spray at 45 angle from all sides - waiting one minute between.

In this case, the sprayed cases had to wait 2 months for my rifle to come in. Cases are gummy sticky to the touch after the hot water/Dawn treatment. Will use more Dawn.

I fully prep (size, trim, chamfer, and polish mouths) clean cases before final cleaning prior to loading.

So you sprayed the cases and let them set for a couple of months with the lube on them? That might very well explain your issues. Wet tumbling in stainless media may get it off with the least amount of work.

I'll second the notion that the wait time is the primary reason you had difficulty removing the One Shot residue from your cases. The main solvent in One Shot lube is hexane, which is extremely volatile. Hornady doesn't indicate in the MSDS exactly what the lubricant dissolved in hexane is, but it is clearly soluble in a relatively non-polar solvent such as hexane. It is not uncommon for organics that are soluble in very non-polar solvents to harden to a sticky residue, or even to an almost enamel-like layer when the original solvent carrier evaporates. Some type of organic solvent might have been a better approach for the One Shot residue after it had dried for an extended period. If you ever decide to go this route, you'll need something less polar than acetone or alcohols, which will not work well to remove the One Shot lubricant. Hexane, dichloromethane, chloroform, carbon tetrachloride, would probably work, but may not be easy to come by. Mineral spirits might also be effective. Alternatively, a much longer treatment with multiple washes using hot water/Dawn might be required to completely remove the sticky residue.

As was mentioned earlier, PIF the one-shot. Lanolin/Heet is the best resizing lubricant I have ever used, zero stuck cases. I had 3 using the RCBS lube pad when I started (probably user error on my part) so I switched and have never looked back.
Cleanup in a pan of denatured alcohol, let dry then clean with your choice of corncob or wet tumble. I prefer shiny brass but YMMV.

That was unintentional. I realized making the 20 P cases from 223 brass w/o having the rifle to check fit was a bad idea. I had already sprayed the cases, so ...

Thanks. Great info.

Hornady one shot lube is formulated not to affect powder. Does this lanolin affect powder if it comes in contact with it say in the case mouth?

I also soak in hot water and dish soap, shake and slosh around a minute or two then triple rinse in hot water. I then soak in Iosso case cleaner for a few minutes then triple rinse in hot water. Cases have never been sticky or gummy after this routine.

I usually grab a few cases at a time by the web then flick wrist to fling out water, then dry in sun or warm breeze of dehumidifier. Kind of a pain in the ass but on large batches it's easier than wiping each case off with acetone.

After sizing and prior to tumbling, I give my brass a quick solvent clean to avoid aging the media prematurely. Cut the full arm off a brushed cotton shirt and tie/sew off the hand end. Toss the brass inside the "bag" and sprinkle mineral turps down the bottom where the brass is. Shake and spin the bag round in random directions for about 10 secs and you'll find it has taken off the residue well. No need to foul towels and get offside with the Boss.

Hard to say. Some reloaders that don't favor the One Shot lube have had issues with stuck cases, which I suspect were caused by using too little of it. I never have that issue, as I liberally soak the cases in One Shot, and I do mean soak liberally. I've never actually even tried to find out whether the residual One Shot inside the case might adversely affect the powder. From what I can actually see and feel on the outside of the case, I've never wanted to find out, so I clean them in Dawn/Lemishine afterward. I know a few people that use the One Shot somewhat less liberally than I do that do not clean their cases afterward and it seem to work for them.

Best way to remove it is to not put it on in the first place. I have been using Imperial Wax for about 20 years now, finishing my third tin. So about 6.5 years/tin.

 

[shoot4fun]

I use alcohol in a non-aerosol spray bottle.

Simple Green, dash of Lemi Shine, 50° C water in an ultrasonic.

Never had issue with the One-shot. I too tumble in untreated corn cob afterward. I use it on large batches. Small batches get Imperial wax and a cloth wipe for removal.

I don't use oneshot but brake cleaner has removed every type of case lube that I have ever tried. Electrical contact cleaner works as well as does alcohol.

 

[boltman13]

I use a Hornady ultrasonic cleaner with either Hornady or Lyman solution then hot water and Dawn. Cases have no sticky feel and have never been a problem.

I am under the impression that the One-shot case lube is designed to be sprayed on and is not required to be removed. Is this incorrect?

if using a progressive loader then cleaning the brass post-lubing is not practical.

If I don't want it on my brass, usually it doesn't bother me, I wipe off with dry paper towel or throw it in the tumbler.

Any sort of lube left on case, chambered and fired is not a good opt for safety reasons..

 

[KenOath]

Assuming that you clean your brass before reloading again, I don't see the need to remove OneShot. It will not affect accuracy and will not harm your rifle.

If case doesn’t grip chamber because of residue left on case this may harm the rifle.
