Does anybody else use baking soda as a bore cleaner? I run a rod down the bore with cloth full of baking soda. It cleans the bore without over-polishing it. Just the right level of grittiness for the bore. What do you guys think? Good idea, or not?
sodium bi carb - mild abrasive, good acid neutralizer/buffer agent good for heart-burn in stomach, has use as tooth paste, removes rust. Probably would not hurt rifle bore but I would prefer to use J-B.
I've never heard of using baking soda as a bore scrub but I would not use any abrasive UNLESS you have a proper bore guide and a proper rod/jag that does not flex significantly and apply pressure to the side of the bore. The rod must also have a good bearing handle to allow free rotation of the rod so it twists with the rifling. I often use Iosso paste on a nylon brush (about every 350-400rds in comp barrels) to get rid of carbon fouling in the edges of the grooves and in the freebore. However, I have one piece fairly rigid freely rotating rod and use Lucas bore guides with the rod insert. I have seen no harm done in at least 15 barrels over the past 5 years...and yes...I have a good scope to check condition of my barrels. Using an abrasive without the above mentioned equipment is inviting problems.
