Not exactly.
Some cheap stuff may be basically rubbing alcohol (sometimes used on eye glasses for example) but not quality lens cleaning fluid for quality optics. Isopropyl Alcohol (aka IPA) is used in many cleaning fluids, but it is buffered, purified to not leave a mineral or oil residue, diluted with triple distilled water, and the evaporation is delayed to help avoid streaks. Some lens cleaning fluids use a combination of solvents that are all purified.
I spend more on couple StarBucks Lattes than I spend on quality lens cleaning fluid each year, so this is not a financial concern. It is more of a protect your expensive glass concern.

isopropyl or denatured ethyl alcohol ie: rubbing alcohols are solvents for mineral or oil residues. Hence they should not leave a film or steaks on a lens. Would not try cleaning a sensor without expert help or advice. That's a whole different ball game.

is the lens cleaning fluid beter than the dry cleaning compound used in the lens pens?...

Great question! There are many differing opinions.
The best answer I have is that it depends on what needs to be cleaned off the lens.
For most "dirt & grime" or fingerprints, the tried and true use of a lens cleaning pad soaked with lens cleaning fluid is best.
Sometimes, there can be a slight film remaining on the lens that the solvent(s) in lens cleaning fluids do not completely remove (you can still see a slight film or smear). The microscopic abrasive action of the popular Lens Pen seems to work well on these and based on published testing, does no damage to the lens or coatings.
Just try to always clean you lens with water vapor and a lens cleaning cloth, followed by a wet/very moist lens cleaning wipe, and then if there is still a visible film, judiciously use a Lens Pen following the manufacturer's instructions.
To me it is a great tool of "last resort" and it seems to easily get the job done.

Thanks! That sounds valueable

The stuff used in Lenspens is carbon black which is not a solvent but a very fine particle sized bit of carbon. This should not harm a lens or filter when used. It will absorb oils and remove things like finger prints. Only concern is that overuse would let it build up and should probably be blown off or wiped off with a microfiber cloth in my opnion. By the way, I usually don't need to clean a lens as I used a UV filter or other. So cleaning a filter that is not that expensive lens makes me feel safer. Enjoyed the conversation.

So did I. Thanks for your input.

I may be wrong and stand to be corrected but by far the most sensitive part of the camera is the sensor, not the mirror (which does not affect the image at all). The mirror is not part of the light path so is irrelevant. Do not just jump in and start swabbing away at your sensor as you will cause irreparable damage. Its often as cheap to get it done professionally as buy the kit.
I will say it again to be very clear. The mirror is irrelevant. It flips out of the way when you press the shutter release, the curtain opens and exposes the sensor. Do not mess with th pe sensor without being super careful. Imagine trying to clean the dust off a fingerprint without affecting the print, it's that delicate and prone to damage if you are careless.
Use a puffer brush on the interior of the body but never use a gas jet on the sensor ever ever. It can discharge propellant which will contaminate the sensor and the power of the jet can permanently damage the delicate shutter curtain.
Think twice, clean once - to paraphrase. You can't un-bust it.

Corect Morkstar, a speck of dirt on the mirror will only show in the viewfinder and is easily removed if it bugs you. It is probably wise to defer cleaning the sensor to someone who knows how and is insured if he botches the job.
I think if one uses caution in chamging lenes ie: not in windy and dusty conditions the need to clean the sensor should be rare. I've never had to. Thanks

First take a an air blower and blow away the front of the lens, the rubber type should be sufficient, then hold the lens against a white sheet of paper and see if you can see any dust, dirt on the lens, look through the rear of the lens and front against the white paper. If you see smudges of dust that was not removed with the blower or brush. Get a lens cleaning cloth, moisten it with some lens cleaner and Windex is not a lens cleaner it could harm the lens coating. Place a drop on the lens or area you wish to clean on the lens and wipe in a circular motion. Check holding the lens against the white paper and see if you can see and smudges. Remember nothing is finished until the paper work is done
