New LNL AP cleaning recommendation

Wipe it down with rubbing alcohol.

The manufacturing/packing grease on the LNL AP is a chore to get off all the small parts. For the powder measure, I think the reason Hornady recommends One Shot (other than because it's their product) is that you need some form of a lube for the rotor and they don't want a wet lube to contaminate the powder. One Shot is a cleaner and also dry lube if left on and not wiped away.

I personally use the One Shot with my LNL AP since that's the vendor standard but I always wear nitrile "exam" gloves. I wear them whenever cleaning or lubing with anything on my bench for guns or reloading. Keeps the chemical residue and, most important for my wife and daughter who have asthma, the smell off my hands.

All the dry lubes I know of are aerosol sprays though if you're concerned about inhaling the vapors. I can tell you that unlike brake parts cleaner, One Shot doesn't seem to have a huge residue bloom/cloud, at least for how I use it.

Use the hornady ONE SHOT Cleaner and DRY LUBE.
Wear Nitrile Gloves.
REMOVE THE POWDER MEASURE O-RING FIRST.

After cleaning and drying the measure, use a small amount
of GRAPHITE and cycle through the measure a few times after
you reassemble it, don't forget to put the O-Ring back.

TALK ABOUT BAD SOLVENTS,
ACETONE vapors and liquid will eat the Nitrile Gloves.
Wear chemical gloves if you use it.
And a respirator also. (the proper one too, not just any)
Acetone will instantly go through your skin.

I cut a CLEAR PLASTIC SHEET PROTECTOR to fit
inside the tube (overlap it)
to protect from powders chemical reaction and discoloring
of the powder measures tube (available at Wal-Mart stationary area).

I cleaned my powder measures with alcohol and did not lube them, wasn't aware any lube was needed. The press didn't really need cleaning, just greased it and hit go.

I'm not sure what the manual says, but the Hornady-published instructional video for setting up the powder measure specifically walks through cleaning and dry lubricating all the parts - http://youtu.be/lqYalPCf3AU?t=4m1s

The nice thing about the OneShot is that provides good corrosion resistance. I use only the OS for LNL lube, shell plate and powder dispense. A can will last a long time this way. If I recall I used brake cleaner to remove all the factory lube.

There is a video series on the Hornady lnl-AP on YouTube by 76Highboy (AKA Bill Morgan)
Google for HORNADY LNL-AP SET UP TIPS AND TRICKS (VIDEO #3 I BELIEVE).

I did a corrosion test last year using steel washers. I test One Shot case lube. It provided very little if any protection. The One Shot was rust quickly.

One Shot cleaner and dry lube, not case lube.

Gotcha.

Hot water and dish liquid will clean off the packing oil. Eezox is a good rust preventive for the metal parts wipe with a small amount on a rag. Remove all excess. Smokeless Powder has graphite coating it that should provide sufficient lubrication.

I think I used mineral spirits to clean mine, although it's a good idea to follow it up with some form of anti-rust protection if you do use it. It worked very well for me.

I dont have a LnL but i clean my press with CRC-QD electric cleaner, it cleans but i do not think it has any lube capabilities. I lube after cleaning with Oil and/or grease where appropriate. Until i know for sure, i am "assuming" the electric cleaner is safe on plastic parts, it dries fast.

Just for fun i inlcuded the MSDS for both.

I had bad results using spray brake cleaner. BAD!

Brake cleaner reacted with the Hornady plastic powder container cylinder. Cylinder became sticky.

Get alcohol solvent at a hardware store. Rubbing alcohol has stuff in it besides alcohol.
