What to Do If Someone Uses a Permanent Marker on Your CommBox Screen

Accidental permanent marker on your CommBox? Don’t worry—here’s how to safely clean it without damaging the screen.

Applies To

All CommBox Screens

💡 Important: Ideally do not use markers on the screen, this can void your warranty

Step-by-Step Instructions

Step 1

Disable touch to avoid accidental inputs

  • Power down the screen

Step 2

Use the right cleaning method

  • Gently wipe the area with a microfibre cloth

  • Dampen the cloth with an alcohol-based cleaner

  • We recommend Isocol: www.isocol.com.au

💡 Important: Do not spray cleaner directly onto the screen—always apply it to the cloth first.

Step 3

Take care with Display Panels

  • If you’re cleaning a Commercial Display Panel, use a light touch

  • These models do not have hardened glass like the Classic or Atom range, so gentle cleaning is essential

Troubleshooting / What to Do If It Doesn’t Work

  • Marker still visible? Repeat the cleaning process with a fresh cloth and slightly more cleaner

  • Smearing? Use a dry part of the cloth to buff gently after cleaning

  • Streaks or residue? Finish with a clean, dry microfibre cloth for a polished look
