How do I clean and maintain my Surefire 5.56, 7.62, and AAC 22 can? What is the average service life of these cans?

I noticed it was smoking after 50 rounds. How many can I safely rapid fire?

Rifle ammo like the .308 burn hot enough that they won't get dirty, much.

I assume the same is true for the 5.56.

For a .22 can you can clean one that comes apart, just don't damage it......

I am interested in this as well. Also I have been wandering what exactly "the dip" is.

Thanks,

A 50/50 mixture of hydrogen peroxide and vinegar. Has to be disposed of properly though because it creates lead acetate after cleaning a can with it.

I just bought an ultrasonic cleaner on Ebay..... Not safe for aluminum either though.

I've used the dip, and if you use the correct protective equipment, you will be okay. Disposal is something to worry about too though. With an ultrasonic, the waste is no worse than lead shavings would be.

Tool1075, what solution are you going to use in your ultrasonic cleaner?

I plan to use water with a dish soap. If it is not doing a satisfactory job, I plan to use something stronger

Keep us posted on the outcomes of the different solutions you experiment with. I like the idea of the ultrasonic cleaner rather than using the dip, having to find a place to dump the toxic dip liquid sucks.

Yeah, I'll let you know.

I don't have a lot of experience with ultrasonic cleaning (just with small jewelry cleaners my wife has used in the past).

I do know that not all cleaning units are created equal, and those that have harder tranducer construction (ceramics, or similar) will probably be more efficient at creating the conditions nessesary for cavitation, given a certain power rating. (i.e. 100W of power consumption by the transducers in one unit may be comparable with 60W in another).

In addition to power, frequency output also influences cavitation in various media, as well as temperature. There are optimum heat conditions of certain liquids to maximize the efficiency of cavitation.

So, when picking a liquid to use, it's probably important to keep in mind the other variables involved so something is not dismissed as useless when it might just need a different amount of heat energy.

Should be fun to mess around with.... I think the fun part is going to be finding something to use as a lubricating solution in which to bathe dry parts post-cleaning.

I think you get what you pay for. The things you probably get with higher cost units are life of the heater units and transducers, life of the attachment of the transducers to the tank, uniformity of frequency sweep throughout for uniform and repeatable cavitation throughout the tank, etc.

Might want to check with the manufacturer, and see what they recommend. I asked YHM about cleaning a 762 stainless suppressor, and here was their reply:

"Sir,
The best way to clean the suppressor is to soak the entire suppressor in
mineral spirits overnight, then remove the next morning and shake the
suppressor out, and then blow it out with some compressed air. Then a
light coat of gun oil may be applied to the outside of the suppressor and
wiped down. Recommended cleaning intervals is after 1000-1500 rounds have
been fired through the suppressor. This is the best method for cleaning
and we have found no better solution than the mineral spirits for cleaning
as it does an excellent job breaking down and disolving the lead and
buildup from the bullets. If you follow this advice for cleaning you
should have no problems shooting .22's or any other caliber through your
suppressor. It is NOT recommended to use an ultrasonic cleaner to clean
the suppressor as there have been issues of metal cracking on the
suppressor believed to have been caused by the ultrasonic cleaner, so they
are NOT recommended to be used on the suppressors."

ultrasonic use causing cracking in aluminum or titanium maybe.... not stainless steel.

and if you think you can shoot .22LR through a 5.56 can and just clean it with mineral spirits..... good luck.

The dip also kills ANODIZED aluminum, all you need it 1 pit in the anodized finish and it will eat it from the inside.

The dip is some nasty stuff but super effective, just ha to stay with Stainless baffles or tubes and you will be fine.

FYI - there is an old but good cleaner on Ebay for cheap right now:

http://cgi.ebay.com/ws/eBayISAPI.dll?Vi ... K:MEWAX:IT

thought I would mention it if someone is looking for one. Less than 4 hours left and it's not even to $100 yet... I don't see it going much past $150 or so, but who knows. good luck :lol:

those units seem to all be made my the same OEM.... and I'm not sure of their quality. There are a lot of them. I almost pulled the trigger on something like that, but saw the Crest unit I got for such a good deal and couldn't pass it up. You never know what you're going to find
