i had the ball head of my tripod get stuck, couldn't get is unscrewed from the shaft. i took it to the camera store. The clerk got some rubber band, put them on the tripod shaft which gave him a better grip. got it loose. thoe rubber bands are still on the shaft. Caution do not rubber bands to tighten any thing.
hi i had the same problem as you. used all the ways that people said to no avail. someone on the hog said get a very large spoon and tap around the edge of the filter untill the filter lets go. i thought what a load of tosh. after 10mins going around filter and trying at times to turn the filter i had to eat my words.it worked fine for me. give it a try.
i think most of the time , the harder you squeeze the filter the more it get stuck .it become deformed when you squeeze it .try holding camera between your knees , use 2 hands , use fingers at 90 degrees .this will put less pressure on the treads .

If the filter was on the lens, how did the dust get on the lens surface?
I see this all of the time

I have a Nikkor 70-200 2.8 lens that I had attached a Hoya UV filter. After shooting in a dusty situation the other day, I attempted to remove the filter to clean the lens surface which had quite a bit of dust on it. The filter is stuck on the lens and I can't unscrew it to remove it. Yikes! Any recommendations. I don't want to damage trying to remove the filter.
Did it ever occur to you to do a search here or google as well as YouTube...?
I believe that when "normal force" is used to unscrew a filter, the threads bind together. Thus, a "gentle" force is more successful for turning the filter without binding the threads.
Yep. Part of the difficulty here arises from dissimilar metals expanding and contracting differently in response to temperature. The filter gets stuck as a result. The remedy here works, only take care as you apply it.
Knowing of this effect, I have applied a very thin coating of petroleum jelly to the threads of the filter, to help with unscrewing it. I also avoid over-snugging the filter in the first place. It doesn't hurt anything if the filter is slightly loose or near so.
I hope this info helps.

If you have a mouse pad, turn it upside down, place the lens flush on the bottom of the mouse pad, and turn it clockwise. Works for me every time. I carry one in my camera bag for that very purpose.
This is why I buy filters made of brass. I useB+W filters.

Are you talking about using a force and leaving it for an extended period to loosen?
Clarification: Paraffin comes in different melting points. High melt point fewer VOCs when you store your camera in your car trunk in midday in Arizona.

Try putting the palm of your hand over the filter and aply pressure as you try to unscrew the filter.

You can buy the nitrile gloves at Lowes or Harbor Freight.
Doctors offices have nitrile gloves of several different colors. I don't believe the color is important, probably just branding.
(At my age I have experience in several different doctors' offices).
Yeah, you can buy them at any pharmacy, hardware, or specialty store, but the MD's office will gladly give you a handful FREE! I have tossed a couple pair in the car's 1st Aid kit, garage toolboxes, fishing tackle boxes, backpacks, and..........CAMERA BAGS!!!
I have used a rubber band wrapped around stuck filters. It gives you a better grip and doesn't cost anything.
