I am wondering what type of liquid I can use to to clean small firearms parts since this looks like these new ultra sonic cleaners should just distroy gun powder build up and general dirt that accumulates on guns. I dont think I want to put my blued/parkerized parts in plain water under the fear that they will rust. What can I use to protect my finish and remove the dirt on small gun parts that will fit in the machine?
 
i used kerosene when i totally stripped my Norc and i used an old toothbrush to scrub it clean. even when wet sanding certain surfaces, the liquid was kerosene and never water.
 
I have a Crest Ultrasonic (1.5 Gallons) It's one of the heated units. I use a concentrate - Crest CC235 (added to plain water) to do the initial clean.

I also have an accessory tank that fits on top that I have full of CC400l (water displacer and lube) that Crest designed specifically for firearms.

If you clean the parts with a water based detergent...it's important to properly lube the parts after to avoid surface rust. The Ultrasonics clean every nook and cranny (including natural voids in the surface of the metal that the naked eye can't see)

You can buy it online from Sonicsonline

They are very good to deal with...and will have machines and consumables in all price ranges.

My guns have never been so clean :D
 
I was hopeing to find something you could make from things you can pick up at local stores.

I dont think you can use kerosene or for that matter any flamable liquids in an ultra sonic cleaner as the longer you use it the hotter the liquid gets due to the vibration of the particals.

if the cleaner bath is sealed / covered, then you ought to be safe - kerosene's auto-ignition temp is over 200C / 400F so that's beyond a kettle (though about oven temp).
 
why would you keep it in an open container, and in the furnace room? i did my cleaning in the garage, or outside when the weather was decent.

if you want to prevent rust, you'll need to avoid using water OR use some follow-up stuff to fully displace the water (even in the pores of the metal), like maybe WD40. kerosene is a great cheap solvent that's probably more stable than gasoline and won't cause rust. to dissolve dirt and grime, you kinda have to use a solvent of some kind, and most are gonna be flammable one way or another. kerosene just happens to be one of the cheapest and most readily available ones - and it's safe on blued or park'd parts (i know from doing my Norc that way)

you COULD do the cleaning in water, but then be sure to follow up with a bath of some kind to get rid of the water. or pop the parts into an over to dry them out, perhaps. of course, water will very likely leave mineral spots when it dries, so you may have to clean THOSE off as well.

FYI - i keep a 9L jug of kerosene in the garage, and used it to clean every single part of my Norc (except the grips), and my motorbike chassis / chain, and all my hand tools, and... and... and... been using it for all sorts of cleaning for 10 years. never had it catch fire unless i actually used it to fill up a lamp with wick and put a match to it.
 
Drew, there is a 6mmBR article on ultrasonics, and there is discussion of different cleaning liquids and effectiveness. I don't have the link handy, but its on that site.

Our ultrasonic cleaner is big enough to fit two .50 brownings (machine guns) at the same time.We have used both jewlery cleaner and simple green bio degradable cleaner.Both worked pretty well when mixed with hot water.Just make sure when you pull the parts out that you wash and dry them of right away and there won't be any problems with rust.
 
so, kerosene can be somewhat carcinogenic if misused, and varsol / paint thinners can really dry out your skin and smell, and both are flammable. yet both are great cleaning solvents that don't require any sort of further care to prevent rust since neither causes rust in the first place....

hmmmm...............

to the OP: here's your choices as i see it. carefully use a flammable solvent and not worry about rust, or use safe water-based degreasers / cleaners while eating dinner and take extra steps to protect from any chance of corrosion happening.
