I spent a lot of money on commercial cleaning products, but this simple method works better and costs next to nothing

The simple steps followed by Nana
Turn off the TV and let it cool completely to avoid any electrical issues or heat stains.
Mix equal parts distilled water and white vinegar in a spray bottle. Vinegar is a natural cleaner that removes dirt without leaving streaks.
Lightly spray the microfiber cloth with the vinegar solution. Avoid spraying directly on the screen to prevent liquid from seeping into the device.
Gently wipe the screen using small circular motions. The microfiber cloth will remove dust and fingerprints without scratching the surface.
Use a dry section of the microfiber cloth to buff the screen to a clear, streak-free finish.
How and why this method works
Nana’s trick is effective because of the properties of the materials used:

Distilled water is free of impurities that can leave streaks or smudges on the screen.
White vinegar, being acidic, breaks down fingerprints and greasy stains.
Microfiber cloths are designed to attract dust and dirt particles, ensuring a gentle but thorough cleaning.
This combination results in a spotless TV screen without the use of harsh chemicals or abrasive materials.
