Can I use Universal Cleaner on TV, monitor, or laptop screens?Updated 8 hours ago

TL;DR: No. Don't use Universal Cleaner on any TV, monitor, laptop, tablet, or phone screen. Alkaline cleaners can damage the delicate anti-glare and oleophobic coatings on modern displays. Use a dry Glass Cloth for the display itself. Universal Cleaner is safe for bezels, stands, and cases when sprayed onto the cloth (not the device) and kept away from ports and seams.

Why shouldn't I use Universal Cleaner on screens?

Modern TV, monitor, laptop, tablet, and phone screens carry delicate factory-applied coatings; anti-glare layers, oleophobic (fingerprint-resistant) coatings, and scratch-resistant films. These coatings are sensitive to cleaning chemistry. Universal Cleaner is an alkaline cleaner (pH 12.5) designed for hard, non-coated household surfaces. It can strip or cloud screen coatings over time, and liquid near ports or seams can damage electronics.

⚠ Never on any display

TVs, computer monitors, laptop screens, tablets, phones, smartwatches, e-readers. These carry anti-glare and oleophobic coatings that react to alkaline chemistry. Also avoid spraying near ports, speakers, or any seam where liquid could get inside.

How should I clean my screen?

Start with a clean, dry Glass Cloth. Turn the screen off (dust shows up better against a dark screen). Wipe in straight lines from top to bottom with light pressure. For stubborn smudges where your manufacturer allows, lightly mist distilled water onto the cloth (never directly onto the screen) and wipe gently, then immediately buff dry with a second clean cloth. Never use tap water (mineral deposits) or ammonia-based glass cleaners on coated screens.

✓ Three-step screen clean

1

Turn the screen off. Dust and smudges show up better against a dark screen. Avoid the risk of a wet cloth touching a live surface.

2

Wipe dry first. Use a clean, dry Glass Cloth in straight lines, top to bottom, with light pressure. This lifts most dust and light smudges without moisture.

3

Stubborn smudges? If your manufacturer allows, lightly mist distilled water onto the cloth (never the screen). Wipe gently, then immediately buff dry with a second cloth.


Can I use Universal Cleaner on bezels, stands, and cases?

Yes, with care. Universal Cleaner is safe for plastic and metal bezels, monitor stands, laptop lids, TV frames, and device cases. Spray onto a Universal Cloth (never directly onto the device) and wipe the target area. Keep moisture away from ports, speakers, vents, and seams. Spot test first on visible surfaces.

✓ Safe for the non-screen parts

Bezels, monitor stands, laptop lids, TV frames, and hard plastic or metal cases. Always spray onto the cloth first, never onto the device. Keep liquid well away from ports, speakers, vents, and any seam where moisture could get inside.
