    Slip 2000 725, M Pro 7, Breakthrough, Hoppes Elite etc...

    I understand some claim to be water-based and others are not water-based but they're not oil-based either and they act like water in that they soak into carbon fouling rather than sit on top of it like oily cleaners (Breakfree or Ballistol).

    I understand these cleaners are not CLP's and they remove fouling but do not lubricate or protect. Also, they remove lubricants and protective oils.

    I'm wary of using water-based cleaners on my revolvers because I've found that even a light spray on the outside of the revolver can make a milky emulsion inside things. But what about the non-water based cleaners like M Pro 7? Can I use that on an assembled revolver or cylinder assembly? Or am I better off stripping it so the cleaner can be removed and it can be lubricated before assembling?

    I believe both MPro7 Gun Cleaner and Hoppe's Elite Gun Cleaner are water based.

    MPro7 denied it being water-based, at least at one point. This thread indicates a link they had that claimed otherwise: http://www.calguns.net/calgunforum/archive/index.php/t-1089771.html

    ...but the link mentioned in that thread is no longer working. If I pull up the ingredients of the Gun Cleaner from MPro7's website, it does list water as the first ingredient: http://jn5zt4b4wys3b729t2n8cw6k.wpe...wp-content/uploads/2019/12/MPro7-070-1040.pdf

    Since I made the OP in November, I started using MPro7. I found it is much more effective at removing carbon fouling than Breakfree CLP, Ballistol, or Hoppes #9. It does strip all lubrication and oil-film surface protection and so it must be followed by a lubricant or protectant if the part requires it. Because of this, I've come to favor it to clean bores, but not other parts unless I'm completely stripping it and re-lubricating it. For example, I will keep the MPro7 out of my revolver's lockwork unless I'm going to take the sideplate off and relubricate it. I will use it carefully (on patches) in the chambers, avoiding getting it in the yoke and ejector assembly that is lubricated. I also avoid contact with any wood. It is much more effective than CLP, Ballistol, or #9 on the carbon fouling around the barrel face and forcing cone. It is not very effective on copper fouling in the bore.

    Never heard of MPro7. How does it work against lead and copper?

    I honestly haven't been impressed with it as a bore solvent.
    Dunno, maybe my perception is different than the OPs.
    Personally, I go with any oil-based solvent for bores. I don't find lead, copper and plastic all that tough to get out with a solvent application followed by a short soak -- maybe 10 minutes -- and some brushing. Of late, I've been using Kroil.
    If I need to chase some copper, I go to the Pro Shot Coppper Solvent IV.

    I've been starting my cleaning regimen with Slip 2000 Carbon Killer. Its water based, and dissolves carbon very well. Two cycles of wet patch followed by a bronze brushing, let soak for 10 minutes, a couple dry patches.

    It does wonders on AR15 bolts too.
