To begin:
Wet cans work best wet, but can be run dry with less effectiveness. Wet cans will always be dimensionally smaller. Thin viscosity ablatives (additives) are quietest, but do not last as long. Water is the quietest of all, but last a round or two. A light oil or grease will not be as quiet but will last longer, figure a grease can last for 6-8 rounds before you can hear the difference. Its a case of practicality and designers, good designers will actually design towards one ablative to insure balancing the limited internal volumes against filling those same spaces. Wet cans are generally always quieter than dry. Large pistol rounds, say .45, even when marketed as a dry can really only sound great when run wet. The baffle design of a pistol wet can is usually flat plane baffle stacks. One should add approximately 5 - 10cc of whatever they like as that is all that is actually required. Light oils, like Remoil can be a nice compromise. Loading the can is made quiet simple with the right tool. Here, grease injector.
#1 rule of a wet centerfire silencer is never, ever clean it. You do yourself no service, none. Its hard enough to get them filthy enough. Wet....no cleaning.
So why would one bother to design a dry pistol can? All civilian market whining about the mess and a small bit of not being able to have ablative available in tactical situations.
Dry cans are designed to run dry, but can be run wet and will be even better. They are dimensionally larger as the additional internal volume is needed. When one designs a dry can, generally cone shaped more complex styles baffles and/or conical grind lead gas pathing is used. One tries to spin the gas more in a dry can, the delay is essential. Pistol cartridge sub guns are usually dry cans. High volume? Dry. Dry cans can take the heat...by design.
Cleaning a dry centerfire can? Not necessary, but a simple flush is all that is necessary. Cleaning a dry can is made simple with the right tool. Here, high pressure hot water.
