Opinions: safest solvent to soak HK USP

My newest obsession, HK USP 9mm REALLY needs a good cleaning; better than just the usual 1-2hrs with brush and Break Free. Heckler & Koch recommends soaking the firearm once a year as a complete cleaning. Any opinions as to a solvent that won't damage the finish? Mine has that Hostile environment black finish, and I don't know just how much hostility it can tolerate. Thanks.

Try MPro7.I use it on several guns,including my glocks.They sell it in 1 gallon sizes for use in the big cleaning tanks.The stuff has the consistancy of soapy water,andi it won't harm any finishes.

MPro-7 happens to be what H&K recommends and uses at its own facilities.

If you elect to soak your USP in MPro-7 and you don't pull the firing pin when you do it, make sure you use compressed air to completely blow out the firing pin channel. MPro-7 can gel with particulants which are deposited in the channel from fired primers and can cause failures to fire due to light firing pin strikes. Down the road this will necessitate the pin be pulled and the channel be cleaned out throughly. I know this from first hand experience.
