Why You Should Throw Away the Newspaper and Ammonia

Homeowners and business owners have passed down the same advice for cleaning and maintaining glass: use old newspapers, spray ammonia, and wipe until it shines. While these tips may sound harmless—and even nostalgic—they can actually damage modern glass, reduce clarity, and shorten the lifespan of your windows. At Action Glass, we regularly see glass damage caused by outdated cleaning myths. Understanding what not to do is just as important as knowing the right way to care for your glass.

Glass Maintenance Matters More Than You Think

Glass today is not the same glass as that used decades ago. Modern residential and commercial glass often includes protective coatings, tinting, low-emissivity (Low-E) layers, and laminated or tempered construction. These advancements improve energy efficiency, safety, and durability—but they also require proper care. Using harsh or abrasive cleaning methods can strip coatings, create micro-scratches, and lead to permanent cloudiness.

Routine, correct maintenance helps prevent premature glass replacement, keeps windows looking clear and professional, and protects your investment. Poor cleaning habits, however, can slowly degrade glass until repair or replacement becomes unavoidable.

The Newspaper Myth: Why It No Longer Works

Old Ink and Paper Are Abrasive

Newspaper cleaning became popular decades ago because paper fibers were softer and ink formulas were less aggressive. Today’s newspapers are different. Modern inks contain chemicals that can smear, leave residue, and stain window frames. The paper itself is often rougher, which can cause fine scratches on glass surfaces.

These scratches may not be visible at first, but over time they scatter light, making glass appear dull or hazy—especially in direct sunlight.

Lint and Residue Build Up Over Time

Unlike microfiber cloths, newspapers shed fibers. These fibers cling to glass edges and corners, collecting dust and moisture. This buildup can lead to streaking that becomes harder to remove with each cleaning cycle.

What once seemed like a “streak-free trick” actually creates long-term maintenance problems.

The Ammonia Problem: More Harm Than Help

Ammonia Damages Modern Glass Coatings

Ammonia-based cleaners are one of the most common causes of premature glass failure. Many modern windows feature Low-E coatings that reflect heat and help maintain indoor comfort. Ammonia can degrade these coatings, leading to discoloration, hazing, and reduced energy efficiency.

Once a coating is damaged, it cannot be restored with cleaning—it requires glass replacement.

Health and Safety Concerns

Ammonia fumes are irritating to the eyes, skin, and lungs, especially in enclosed spaces. Mixing ammonia with other household cleaners can create dangerous chemical reactions. From a safety standpoint alone, ammonia-based products are no longer recommended for routine glass care.

Common Glass Cleaning Myths That Still Cause Damage

“More Pressure Means Cleaner Glass”

Applying excessive pressure while cleaning can grind dirt and debris into the glass surface. This creates micro-abrasions that weaken glass over time. Gentle, consistent wiping with the right materials is far more effective.

“Any Cleaner Labeled ‘Glass Cleaner’ Is Safe”

Not all glass cleaners are created equal. Many contain additives that are harmful to tinted, laminated, or coated glass. Always check labels and avoid products containing ammonia, high concentrations of vinegar, or abrasive compounds.

“Hard Water Stains Will Eventually Wash Away”

Mineral deposits from hard water bond to glass surfaces. If ignored, they can etch into the glass, making stains permanent. Professional treatment is often required once etching occurs.

What You Should Use Instead | FAQs

Microfiber Cloths for Cleaning Glass

• Microfiber cloths are designed to lift dirt and oils without scratching.
• Reusable, lint-free, and far superior to paper products.
• Using two cloths—one for cleaning and one for drying—helps eliminate streaks.
• Non-Ammonia, pH-Neutral Cleaners on Glass

NOTE: Look for cleaners specifically labeled as ammonia-free and safe for coated glass. Mild soap mixed with water is often sufficient for routine maintenance and poses minimal risk to glass surfaces.

Soft Water and Proper Drying

• Use distilled or softened water to prevent mineral spotting.
• Drying the glass immediately after cleaning reduces streaks and water marks.

When Cleaning Isn’t Enough

If your glass looks cloudy, scratched, or stained despite regular cleaning, the issue may go beyond surface dirt. Damage from improper maintenance, environmental exposure, or impact can weaken glass and compromise safety. In these cases, professional evaluation is essential.
