Is this Cosmetic Damage, caused by me

[Morphy69]

Hi, I have a Samsung UE50AU9000 50" 4K Ultra HD TV which is 14 months old.
After speaking to a chat advisor online and posting some pictures, she advised me that my screen has been damaged by the products I used to clean it.

I use a microfiber cloth and a cleaning solution called Mistify natural screen cleaner, made especially for TVs.
I also use this kit on my sony tv with no issues. 

My tv has a 5-year warranty, but is worthless as it won't cover the problem, neither would it cover it if it was still in its 12-month period she said.

Has anyone else had this issue before?

I have come across this with cleaning products being the culprit. Although the product is made to clean tv's. What you should look into is what Samsung actually recommend for their tv's. I know someone who uses something similar and has been fine. For me when I clean my TV it's just a damp micro fibre cloth, just with water, and a dry one to go over it. You do need to be careful what you use so it doesn't damage the coating. It is pretty bad if it is the product though, as this is the reason for purchasing as its meant to be for tv's. I just don't trust anything but a damp or non damp micro fibre.

Hi Fiona and thanks for the reply, she asked me if I used water as if to imply if I did that would be the problem.

The tv was in the bedroom so not really used much or cleaned as much as the tv in the living room, apart from the usual wipe over with the micro fibre cloth to remove the dust. 
Strange one really tbh.

I would agree with Fiona looking at other posts and the tv damage that has been caused by cleaning products this is identical. Unfortunately.

@Morphy69: Typically, we do advise against using cleaning agents when cleaning your TV screen. For general cleaning of the frame and screen of your TV, you should use a soft, clean, lint-free, dry cloth. We recommend using a microfibre cloth. 

You should never use any type of window cleaner, soap, scouring powder, or any cleanser with solvents such as alcohol, benzene, ammonia, or paint thinner. Never use abrasive pads or paper towels. If you do, you can scratch the screen or strip the anti-glare coating off the screen and cause permanent damage.

The only thing you need to clean any screen is a slightly dampened cloth of warm water and a dry cloth for the final wipe, Screens come up perfect every time.

These so called cleaning solutions have been making a mess of some screens since they were introduced years ago, They are a complete waste of money.

So will this have any long-term effect on my picture quality, when the tv is on it's barely noticeable, but more so when powered off.

Old post but misinformation. Water and microfiber will not clean smudges off the coating (QE65S90D), it'll just spread around and if you keep trying to get smudges off with only water + microfiber at it, you'll damage the coating. Fun. Happened to me with <1 month old TV, and it's £1090 to "repair" it. Double fun.
