Cleaning Silencerco Sparrow

[dieselrealtor]

Ran about 1k rounds through it, cleaning the core & clamshells.

There are carbon/lead lines on the inside of the tube from between the clamshells, is there a good way to clean this?

Soak it in Kroil overnight and then push the baffles through a couple times. Usually gets most of it.

Smack it on the concrete floor?

I think I have a waffle head framing hammer

I haven't used Kroil much, I presume it is ok for the aluminum tube?

Kroil is safe for all metals and plastics (polymers). It might be good to avoid using it on wood.

The Hornady ultrasonic cleaner doesn't seem to be touching the crust on the clamshells, using a 50/50 simple green/water mix.

22oz is the shizzle for knocking the fungus off things.

I haven't used this yet, but it gets pretty good reviews. https://ads.midwayusa.com/product/1...qwOGoxKvpt27IxRJr4YcnHjMQC6zZ3XBoC7tEQAvD_BwE

Now thats interesting, I was thinking of buying one just for that reason.
I wonder if the purple stuff is any different?
I though Andy used that stuff.

Yes. I use it on mine.

No. In my experience, the ultrasonic won't touch most of it w/o some toxic chemical mix. I mostly scrape and soak. Some breech plug grease when you slide it back together makes it clean easier the next time.

$160 a gallon? Thanks, but no.

I used the Breakthrough and it's pretty good for an overnight soak. Better than the Ballistol can cleaner at least. Just remember to dump it all into a resealable container, you can get at least 4 to 5 uses out of it because it won't clean anymore.

Ultrasonics are good for softening up the deposits on the baffles but you still need to wipe it off. Unless you got one of those giant industrial high voltage ultrasonics, then those will strip off anything. I had a Lyman brand I got on Midway and they are great for brass, jewelry, glasses, and mouth guards. But I tried using Hornady gun parts solution with a BCG and it didn't take everything off. Also the Lyman Ultrasonic Cleaner can be found at Harbor Freight for cheaper as an off brand.

If I am not mistaken, the Sparrow has SS clamshells but the monocore is aluminum.

Be careful how long you leave the monocore in an ultrasonic.
An ultrasonic can eat through aluminum foil in minutes...it may pit the monocore if you leave it in too long.

Here is a guide on cleaning aluminum, in an ultrasonic.

I would be tempted to put the core in my corn cob tumbler.

I see no issue with that. Not sure it will do much but...you never know.
