I'm installing an aerator on a sink in which it's aerator has not been

quite a bit of rust on the inside (apparently), or if it's not rust,
it's probably glued on. Are there any suggestions on what I should do?

I've attempted the pliers, the wrench, as well as manually screwing it
off. All of my attempts are 100% fruitless so far. I've even tried the
hair dryer and ice, but that didn't work either.

Dumb question time.... are you sure you're turning it the proper direction?
