Ultrasonic for bolt and carrier?

[rtr]

Will cleaning my JP bolt carrier and bolt in my ultrasonic hurt anything? What cleaning solution and for how long?

I tried it, in tap water.

Not much happened at all in terms of cleaning so need advice on what to add.

Gun shoots fine.

I doubt it would hurt anything. I would use a recommended cleaner or maybe some lemi shine in water or simple green. For best results I would take the bolt out of the carrier. I may look into this for the top end of my pistols. DO NO clean things aluminum with simple green as it can remove anodizing. Please don't ask how I know.

So how much simple green and how much water?

Hornday ultrasonic cleaning solution or the solution from L&R (they make most of the good Ultrasonics)

I used to do that right up until the rifle quit working. Found I was getting a ton of sludge in behind the ejector. Got to try pulling it and fixing it in my hotel room at Arizona Charlies without the right tools. Not a fun experience. When I finally got the ejector out it was basically a solid plug of gunk behind it. I don't ultrasonic anything any more unless it's completely disassembled.
