I am using a UV filter made by Zeikos on my Canon lens, but I cannot remove this (it has become stuck on the lens). I am worried about forcing it due to the risk to the lens. Can you recommend a product that can be used to help loosen the UV filter? I currently live in the Peruvian Amazon so mail order of a product is not possible, rather I need to know what can be used so I don´t put anything on the lens that could damage it. Many thanks!

A little heat will loosen the filter right up. I recommend using a hot hair dryer and heat the filter up then unscrew. You can use a flat pan with a thin layer of very hot water, dip the filter in (take care not to wet the lens) then unscrew. Remember to use a rag or gloves to keep from being burned.

Yes, that can be a pain. If the hairdryer does not work, try setting the lens filter-down on the counter on top of one of those floppy rubber grippy jar openers. Turn the lens (in the correct direction) and see if that will do it. This puts even pressure on the filter ring rather than pressure on just 2 places like if you were trying it with your hand. It keeps it from binding worse.
They also sell "filter wrenches" at B&H, Adorama, etc. They are cheap. I need to get one of those myself.

If the hair drier doesn't help, try this: put the lens upside down on a rubber cutting board (or any rubber flat surface), this will give you good and even grip/traction on all filter surface. Then try to rotate in the correct direction.

My problem was a brand new lens and a brand new filter. Screwing and unscrewing it few times made it less tight.
But good tips with the rubber surface and filter wrenches. Maybe I should invest in some wrenches.
I personally experienced similar problems, fortunately never had the filter completely stuck.
But since then I do this: put the filter over the lens thread and rotate the filter a bit in the oposite direction until it completely
"fits" on the lens thread, then rotate the filter in the right direction, trying to never overtighten it.
As stated many times out there, the filter is the final step to "weather seal" a "L" lens, so it's extremely important indeed. And of course you protect the front element.
We use to carry two kind of protection UV filters: one multicoated (expensive) and another without coating (cheap). The reason is because the multicoated filters are usually hard to clean, but deliver better image with less internal reflections (especially noticeable at night scenes with light spots on the frame, etc). But when we shoot in a situation we already know the filter will get durty, then we use the cheap filter (easier to clean, but still protects the lens).
Hope you can get your filter removed!

I had the same problem- I figured out how to remove the filter without breaking or damaging the lens- visit my blog for the full article http://www.graysonhoffman.com/uv-filter-stuck-now/
