For future reference: How to clean your Apple products - Apple Support

"Don't use window cleaners, household cleaners, aerosol sprays, solvents, ammonia, abrasives, or cleaners containing hydrogen peroxide to clean the display."

Also, you need to be made aware of the fact the damage may not be limited to the display. It might also involve the logic board, cables, maybe the battery, etc. Replacing all those parts yourself could get expensive in a hurry.

If take it to Apple they will accept all the responsibility for fixing it.

Hi.

It seems like the reason why your Mac has an issue was solved, but fixing the Mac was not solved.

Going to Apple is actually the best, trusted, and the recommended way to fix your Mac.

If you don't want to pay for the repair and services, try checking the coverage of your Mac.

Most of the Apple devices are shipped with 1 year free coverage, which means they will fix your Mac for free in 1 year you bought your Mac. So when did you buy it?

You could also just simply check your Mac's coverage by going to System Settings, "General", and "AppleCare and Warranty". Then select your device.

For more information about Apple's coverage, check out the websites below:

1. AppleCare Products - Apple (Check your Apple Device's coverage)
2. Check Your Service and Support Coverage - Apple Support (More information regarding to Apple's repair services)

Thanks

You can take it to an authorized service provider or try self service repair as noted above.

And don't EVER spay a liquid of any kind on the screen. If you need a damp cloth to clean something off the screen, use a slightly damp cloth.
