In Sept of 2022, I purchased a inexpensive single action .22, planning on having it to train my grandchildren on the proper handling of a handling of a handgun. At the same time I purchased a bottle of bio-degradable oil, advertised as useful for gun cleaning and "everything else". I put the revolver away planning on using it in the spring when one of my GC. was a little older. Last weekend I got the revolver out of the safe to use. The cylinder would not revolve. I had to disasemble the gun and use some good ole H#9, to clean the sticky gum off of the parts, and reassemble it.
Nothing was damaged, BUT, I don't think that bio-degradable is a good oil to use on a firearm. It may have been just this particular brand, but be cautious of bio-degradable gun oils.
I did find out that bio-degradable oil makes a wonderful penatrating oil, the best that I have ever found.
