My Secret -
Simichrome a product from Germany; found in most automotive
supply houses, or bike shops. Its what most biker's use on their chrome
on motorcycles. It does contain a very fine abrasive; but it you use it
the way it should be used, well you won't have any problems. Don't
bear down hard like a "wild man" when polishing. Very little elbow
grease is needed; let the product do its job~! Its like Brylcream, "a
little dab will do you". Shelf life is long, approximately 10 years; cost
is 'bout $7.00 per tube, also available from Highland Woodworking~!
I use it to clean the gunk off the face of the cylinder; and to clean any
excess powder residue off of the firearm~!
