How to Clean Interior Signage Without Causing Damage

COVID Solutions

Interior signage is an essential part of any professional space—whether it’s ADA-compliant wayfinding signs, office directories, or branded wall displays. At Architectural Identification, we design and manufacture durable signage systems that are built to last. Our new encapsulated signage system is engineered for longevity, clarity, and everyday use.

Our encapsulated system is especially easy to care for. With all raised copy and braille “encapsulated” beneath the face of the sign, the surface can be wiped clean quickly without damaging tactile elements or reducing accessibility.

Best Practices for Cleaning and Maintaining Interior Signage

Keeping your signage clean not only preserves its appearance but also ensures accessibility and compliance. Here are some expert tips:

  • Use soft, non-abrasive materials. A microfiber or cotton cloth is ideal. Avoid paper towels or rough sponges that can scratch acrylic or laminate surfaces.

  • Choose gentle cleaners. Warm water with a drop of mild dish soap is usually all you need. Avoid harsh chemicals like bleach, ammonia, or alcohol-based sprays, which can cause clouding, fading, or adhesive breakdown.

  • Spray the cloth, not the sign. Applying liquid directly onto signage can allow moisture to seep into edges, damaging substrates or mounting. Always dampen your cloth first.

  • Dust regularly. Routine light dusting keeps signs looking professional and prevents buildup that becomes harder to clean over time.

  • Wipe fingerprints and smudges promptly. High-touch signs, such as ADA signage with braille or directional panels near doors, can collect oils from hands. A quick wipe keeps them clean and legible.

  • Handle tactile elements carefully. When cleaning raised letters or braille, use light pressure to avoid unnecessary wear.

  • Inspect mounting and edges. During cleaning, check that your signage is still secure and aligned properly on the wall or mounting system.

  • Test before using new products. Always try any cleaner on a hidden corner first to ensure it won’t damage finishes.

Why Proper Signage Care Matters

Well-maintained signage enhances both the look and function of your space. Clean, legible, and damage-free signs:

  • Reinforce brand professionalism

  • Ensure ADA compliance and accessibility

  • Extend the lifespan of your signage investment
