I take the lock off the rifle. I have a tooth brush by the kitchen sink. I make up some soap and water. Dunk the lock and then start scrubbing with that tooth brush. After that I rinse it in clean water. I then spray it with brake cleaner or carburetor cleaner. Then I take an air compressor and blow the whole works dry. After that I give it a light spray of Rem Oil with Teflon and after wiping out the stock with oil, put it all back together.
