Huge mistake with new 57!!

The old Hoppe's formula had nitrobenzene in it. Great solvent, but toxic and carcinogenic. So out it went.

Following Hickock45's advice, Ballistol is all I use to clean and lubricate guns anymore. Non toxic and effective.

Like I tell my students, I know it's a bummer but you need to read the instructions...

Ditto on Ballistol, I use it on everything, (it's great!) but I believe it is alkaline.

I also use CLP interchangeably, no problems with either, but don't have any "new" blue guns.

From S&W instruction page 32

CAUTION:
Some cleaners can cause damage to your firearms.
You should avoid prolonged solvent immersion and prolonged ultrasonic cleaning of your firearm.
Choice of solvent should be restricted to those products specifically developed for firearms maintenance.
Damage to a firearm's finish may occur if these cautions are ignored.
Ammoniated solvents or other strong alkaline solvents, should not be used on any Smith & Wesson firearm.
Cleaning is essential to ensure the proper functioning of your firearm.

One maker of deluxe 1911s recommends you not put anything stronger than WD40 on their guns.

I'd feel pretty bad to lay out big bucks to a company that recommends WD40 for it!
