Case cleaning and long time storage.
In the 50s Bell and Mull listed a formula for cleaning cases for long time storage, 2% So3 (count the 'O's), the difference between then and now? They added a time limit, something like 3 minutes max then rinse twice ect., ect..
I collect old tools, cheap old tools, cast iron pots and pans, cleaning for me is never about the grinder, file and sand paper, more times than not I apply the leaver policy, I leaver the way I founder, BUT with old cheap tools I use vinegar, before I start cleaning and with a new jar of vinegar I can drink it or put it on a salad, When cleaning with vinegar and cast iron and old tools the user has plenty of time as in hours before the cleaning gets serious but vinegar is an acid, from 4 to 6%, to gain time, add water.
Cleaning with peroxide/vinegar solution:
Peroxide is an acid and is corrosive, count the 'O's, when cleaning brass cases the acid goes after the zinc, that is the reason time should be a factor. LEAD? Batteries have been made with lead plates from the beginning, in a solution of H2SO4 (count the 'O's) the plates in the battery have been known to fail, the most unlikely reason for battery failure would be due to the acid, point? (Or question) If mercury removes lead because it has an infinity to lead how does an acid remove lead if it does not have an infinity to it, then there is the amonia and rust, amonis does not create or cause rust UNTIL the metal is exposed to the atmosphere (air with humitity and we are not talking about fog and or rain).
Peroxide is a good thing and has many good uses, like making oxygen, when pored on a cut bubbles appear, the bubbles are oxygen, the same bubbles appear when poured on a fresh cut potato.
