How should I maintain my Metal Channel Letters?

Metal Channel Letters often have a sturdy base such as stainless steel. However, the front material is made of acrylic, which may need extra care. To clean metal channel letters, make sure you’re using gentle cleaning agents to avoid scratches or permanent damage.

Materials Needed:

Mild soap 

Lukewarm water

Soft, non-abrasive cloth or microfiber towel to avoid scratches

How to clean

1. Get rid of the dirt first. You may use a leaf blower to remove debris and dirt from the sign. 

2. Dampen a soft, non-abrasive cloth or microfiber towel with lukewarm water.

3. Wipe the channel letters with the moistened cloth to remove grime. Add mild soap to the water if needed. 

4. After cleaning, gently blot the sign dry with a soft, clean cloth and allow it to dry.

AVOID THE FOLLOWING

• Abrasive Materials: Do not use sponges, abrasive scouring pads, melamine foams, or brushes, as they can scratch and damage the surface of the signage.
• Incorrect Cleaning Products: Harsh Chemicals: Products like glass cleaners, polishing waxes, or all-purpose cleaners may damage the acrylic front cover. Always check the label to ensure that the cleaner is suitable for the signage material.
• Harsh Chemicals: Products like glass cleaners, polishing waxes, or all-purpose cleaners may damage the acrylic front cover.
