Had same thing happen with dollar store "purple power". Must be the effect of caustic (low pH) on the H&R CC???

I would imagine that there are complexing agents in most of these new cleaners that will pick ferric and ferrous ions off metal surfaces without dissolving the base metal. Of course, bluing and the oxidation colors formed by color hardening processes are forms of iron oxide, or rust, and this would go away just as easily as surface rust of any other kind.
I remember when Ballistol came on the market over here, some guy on the old Shooter’s site thought so much of it that he stored his Colt Single Actions in ziplock Baggies, slathered in the stuff. Next time he checked them, his mint finishes were 75%, his 50% finishes were 25% and his 25% finishes were gray metal. An expensive lesson.
Caustic is high pH, Acidic is low pH.
Not saying caustic won't damage a firearm, but even a weak acid like the vinegar or citric acid will remove bluing (both relatively mild acids, but "low" pH).
Concentrated simple green is mildly caustic/alkaline according to online reference. (8.5-9.5)
All the Biofriendly solutions will do pretty much the same thing. I've used most of them to remove lasered powdercoating from yeti type cups. Shines stainless up well. Now evaporust is a bit different, if you have an old solution that has some residual grease or oil in it, you can get a nice black finish on steel..... and it wears well....

I wonder if this is one way to achieve a French Grey finish. I remember reading somewhere that one technique used was to color case harden the part and then buff the colors off with 4-0 steel wool.
The original Simple Green is relatively corrosive. The aircraft version is much better in not being corrosive.
