I didn't want to drift benny's thread asking about ultrasonic cleaners, so here are some quesions I have for you folks that use them:

1) After cleaning, what do you lubricate and how?

2) Is there anything that should not be lubricated - (firing pin, firing pin channel, etc.)?

3)Is ultrasonic cleaning safe for chrome-lined barrels?

4)Is ultrasonic cleaning safe for night sights?

5) What types of material should not be cleaned via the ultrasonic method? Is it safe to do polymer (Glocks, etc.)?

I have a Hornday "Lock-N-Load" ultrasonic cleaner and have only used the "One Shot Gun Parts Solution" and distilled water as per Hornday recommendations. ( I've heard that hard water might be a problem for oxidation/discoloration on some guns)

I've cleaned Glocks, AR's, Remmington 870, a blued Ruger 10/22, S&W revolvers (Stainless and blued), S&W shield, Colt's, BHP's, Walther PPk Stainless, Beretta 92 series pistols.

The only things that went "wrong" is the enamel on the safety on the Walther and one of the Berettas came off.

No problems on any of the night sights, even the Hi-vis sights from Meprolite. No problem on chrome lined barrels either.

I'll clean the gun in the ultrasonic, rinse off with fresh water, then blow it off with compressed air. When I say it takes off every bit of oil & lubricant, it takes off EVERY BIT! Yes, it's slightly labor intensive, but it's worth it to me.

Here's the problem- now there's no oil on the steel to prevent rusting. One of those silicone cloth wipes or a very light coat of a thinner oil (Rem Oil) has done the trick for me.

After that, just regular lubrication (frame and slide rails, barrels et al.) will do.

I don't recommend using it after every range session, just when the gun gets really dirty.

I own a Lyman ultrasonic cleaner. In addition to cleaning guns and parts, it can also re-oil them. They offer an ultrasonic gun lubricant. Basically after you clean the gun, you can drain and clean the reservoir then add in the lube and re-run the gun through the process. The same cleaning action now coats the entire thing with their lube.

Before you ask me, I bought it a few years ago and then was delayed in getting it set up due to a boat load of reasons. I can't actually give you a report on how well it works. I did venture to the 2019 NRA annual show in Indy that year and met with the Lyman people. They basically answered all of my questions satisfactorily so I have no fear about using it as intended when I can return to getting my toys dirty.

I use Lucas oil and grease after parts have gone through the US cleaner. I lube manually, works well. No need to apply excess lube.
