I have two filters that have gotten stuck together. Some time back, in a hurry, I put a B&W polarizer filter on top of a UV filter (actually, I forgot the UV filter was there!). Used the polarizer a few times. Then, I went to use it one day, and nothing turned, so I thought I had taken if off. However, it wasn't in its box in the camera bag. Well, when I had the lens and camera tuned, one of the comments from the repair people was that they couldn't clean the filters because they wouldn't come apart.
Any suggestions? Is there some release agent that might work without damaging the filters themselves?

In succession try a drop or two of the following on the joint between the filters: WD40, 3in1 machine oil, liquid wrench.
Let the liquid soak in for a few moments then try to unscrew the filters using filter wrenches or other tool that won’t deform or damage the filter. If the WD40 doesn’t work, try the second one in the same way. If none of the fluids work, you might try heating the filter that has the female thread with a hair dryer to get the metal to expand a bit. If all that fails, buy replacement filters and call it day.
