I have a few carboys that over the years have some lime or film residue
inside. Clorox or CLR won't remove it. Does anyone know what I could try to
clean these up with?

Sand. Thow some sand in there with the cleaner and shake well. Also
letting the carboy sit for a day full of bleach water might do it.

If bleach wouldn't remove the residue, try some hydrochloric (muriatic)
acid. Just don't mix it with any other chlorine-containing chemicals to
avoid release of free chlorine. HCl is the main ingredient in scale
removing products for bathroom (porcelain, glass) surfaces and it works
well. Get it from building supply store in tile/grout area, pool supply
store, etc. Neutralize with baking soda, keep it out of your eyes and off
your skin when concentrated.

Make a strong solution of "Pink Stuff".....enough to fill the carboy
and leave it over night. It should do the trick. If you have a yellow
"sediment" in the morning then you know it has done the job.
