Hi Mike

Is it stainless or blued steel.
For stainless, you can just remove the grips and put it in a sink of hot water and clean it up.
Some men put them in a dish washer.
For blue you will have to dry it out when you are finished cleaning it up, if you use water.

I owned one of them many years ago. I shot it a lot. It was blued. In fact, the stainless ones didn't even come out until many years later.
They are not hard to clean.
Always remove the nipples and clean out the threaded holes. I would grease the threads before I put them back in the cylinder.
Clean the bore with a brush as you would any revolver, and swab out the chambers. Oil everything when you have finished cleaning it up. Be sure to get the insides of the chambers and the bore too, I light coat of good oil is all you need.
