Touch screens are now essential in industrial, commercial, and public environments. Whether used in factory HMIs, outdoor kiosks, retail terminals, or medical systems, regular cleaning is critical for readability, hygiene, longevity, and accuracy.
This guide explains how to clean a touch screen properly, what tools and supplies to use, and how often to clean based on your usage scenario.
Why Proper Touch Screen Cleaning Matters
Industrial and commercial touch screens are subject to:
Finger oils and smudges
Dust and debris
Chemical exposure
Moisture and condensation
Microbial contamination in public areas
Improper cleaning can cause:
Screen haze and reduced visibility
Damage to anti-glare (AG), anti-fingerprint (AF), or anti-reflective (AR) surface coatings
Touch sensitivity issues
Corrosion of edges and seals
That’s why a cleaning process tailored to industrial displays is essential — both for operators and maintenance teams.
How to Clean a Touch Screen: Step-by-Step
Step 1 — Prepare the Right Cleaning Supplies
Before you begin, gather:
✔ Microfiber cloth (lint-free) ✔ Screen-safe cleaning solution (alcohol-free and ammonia-free) ✔ Distilled water (optional) ✔ Spray bottle — never spray directly on the screen
⚠ Do NOT use paper towels, abrasive cloths, window cleaners, or household disinfectants that contain bleach or strong alcohol. These can damage screen coatings.
Step 2 — Power Down the Device
Always turn off the touch screen or disconnect power before cleaning. This avoids static interference and ensures you can see all marks clearly.
Step 3 — Dust Removal
Use a dry microfiber cloth to gently remove loose dust and particles.
Start from the center
Work outward in light circular motions
Avoid excessive pressure
Removing dust first prevents scratches when liquids are applied.
Step 4 — Apply Cleaning Solution Correctly
Do not spray cleaner directly on the screen. Instead:
Lightly mist the microfiber cloth
Wipe the screen in gentle, overlapping strokes
Keep liquid off edges, ports, and sealed seams
This preserves the integrity of touch sensors and glass coatings.
Step 5 — Final Wipe and Dry
After cleaning:
Use a dry microfiber area of the cloth
Buff in gentle circular motions
Remove any streaks or remaining moisture
For high-touch systems like public kiosks and self-service terminals, repeat cleaning daily or multiple times per shift.
Best Cleaning Solutions for Touch Screens
Recommended:
Screen-safe industrial cleaning sprays
Isopropyl alcohol < 70%(only if manufacturer allows)
Distilled water mixtures
Avoid:
❌ Ammonia-based cleaners ❌ Glass cleaners with high alcohol content ❌ Abrasive scrubbing agents ❌ Paper towels or tissues
Using the right cleaning chemistry ensures long-term performance and maintains protective surface coatings like AG, AF, and AR glass treatments.
Cleaning Frequency: What’s Best for Industrial Use?
Ambiente
Recommended Cleaning Frequency
High-touch public displays (kiosks, POS)
Daily
Medical or laboratory touch panels
After each use / shift
Factory or workshop HMIs
Weekly
Outdoor rugged displays
Bi-weekly or as needed
Low-touch internal terminals
Monthly
Optimizing cleaning schedules improves uptime, hygiene, and operator satisfaction.
How to Clean Different Types of Touch Screens
Capacitive / Projected Capacitive (PCAP) Screens
Use gentle cloths
Avoid strong disinfectants
Ideal: alcohol-free screen-safe sprays
Resistive Touch Screens
More durable, but sensitive to scratches
Same process applies
Industrial Panel PCs and Outdoor Displays
Check manufacturer specifications
Outdoor models may tolerate more robust cleaning solutions, but still avoid abrasives
Common Mistakes and How to Avoid Them
❌ Spraying liquid directly on the screen ➡ Use misted cloth instead.
❌ Using rough cloth or paper towel ➡ Switch to microfiber.
❌ Using strong disinfectants indiscriminately ➡ Use approved solutions only.
❌ Ignoring the edges and seal areas ➡ Avoid liquid creeping into seams.
How to Maintain Touch Screen Coatings (AG / AF / AR)
Many industrial screens include surface treatments like:
AG (Anti-Glare) — reduces light reflection
AF (Anti-Fingerprint) — resists smudges
AR (Anti-Reflective) — lowers reflection and improves clarity
To preserve these coatings:
✔ Use alcohol-free cleaners ✔ Avoid abrasives ✔ Clean gently and regularly ✔ Follow manufacturer guidelines
Proper maintenance extends the life of protective glass treatments and keeps displays looking new.
