Bore solvents

We used oven cleaner to remove bearing material from chrome plated crankshafts when we spun bearings. Dont think I will use it on my Krieger bbl.

We would use the acid on one that spun the bearings if it looked like it hadn't tore up the journal that way we could mike it to see if reusable or send to grinder.
Like I said anyone wanting to restore an old rusty gun it works great to clean off the rust for bluing and or repair a do it your self thing save money.
