Basically PB Blaster penetrates rust, loosens it to allow some rusted parts to be loosened easier. Otherwise heat, cool and penetrant. It has virtually no rubbing type of lubrication. Everything will wear out quickly if U continue to use it on a firearm. Use an actual cleaner lubricant if U choose. Watch Hitchcock 45 on U tube. He will spray the bolt generously with his brand.
