The answer is not an absolute yes or no, but rather a “yes, but…” that depends on the type of product. Most household glass cleaners are formulated with ammonia or alcohol, substances that are harmful to modern screens.

Why Can It Be Harmful?

1. Ammonia: Very effective for glass, but it is an abrasive compound that can irreversibly damage the anti-reflective and oleophobic coatings (against fingerprints) of monitors, laptops, tablets, and especially mobile phones. Over time, it will leave the screen dull and prone to scratches.
2. Alcohol (Isopropyl or Ethanol): Although it is safer than ammonia and is used in specific solutions for electronics, in high concentrations it can degrade the coatings. Household cleaning alcohol usually has an inadequate concentration.
3. Aggressive Chemical Products: Fragrances, surfactants, and other additives in these liquids can leave oily residue or permanent stains on the screen.

The Correct and Safe Way to Use It

If you decide to use a generic glass cleaner, the key is indirect application:

• NEVER spray the liquid directly onto the screen. Excess liquid can seep through the edges and damage the internal components.
• Spray a small amount of the product onto a clean, slightly damp microfiber cloth.
• Then, gently wipe the cloth across the screen in circular motions.
• Finally, dry with another dry part of the microfiber cloth to remove any residue.

Conclusion and Recommendation

Although it is possible to use it with the correct technique, it is not ideal. For safe and optimal cleaning, the best practice is:

• Screen-Specific Solution: They are free of ammonia and alcohol, or contain them in a safe concentration.
• Distilled Water with a Touch of Vinegar: A safe homemade alternative (50/50 mix) always applied to the cloth, never directly on the screen.

In summary, common glass cleaner can work in a pinch and applied correctly, but to protect your investment in your devices, products designed specifically for screens are the safest and most recommended option.
