I have french grayed blued & color cased actions over the years via this process. Strip the action, degrease, warm action/part in sun until hot, submerge or coat in Lysol toilet bowl cleaner & leave so phos. acid can loosen carbon nodules. Degrease steel wool & compack into a hard pad. Remove part from cleaner & repeatedly scrub with pad until enough color removed. You will probably have questions ---- feel free to call me for answers or help. Ken
