quote: Be careful to keep the water out of the action, though. On the 1851 Navy, the barrel is held on by a retaining wedge, driven in from the left-hand side and held in place by a spring-like keeper. If you use a plastic mallet and hold your tongue just right, you can tap the keeper down and push the wedge back, both at the same time. Then pull the wedge out and you can pull both the barrel and the cylinder off of the frame.
Now you can soap and wet the barrel and the cylinder to your heart's content. Use a damp soapy rag to wipe the hammer, hammer groove, cylinder advance mechanism and the cylinder pin.
As someone else has mentioned here, you can dry the barrel and cylinder in an oven at 200 degrees.
Just be sure to use a plastic mallet for removing and replacing that wedge -- unless you want that "weathered" look....
