i have been using an amonia glass cleaner on patches for the first few passes through the bore, then solvent, then lots of oil, never had any rust issues, only one when it went 12 hours without cleaning and the bore had very monor surface rust that brushed away easily,
latley i havennt heard of the "Windex" as a bore cleaner trick anymore. when i first got my CZ this amonia glass cleaner trick was king, does no one do this anymore?
also ive never has issues with rust in the action, i clean it everytime now because i like my guns clean but i used to only clean the bore and gas system and i never got even the slightest bit of rust in the action, corrosive is well worth the cheaper cost IMO
