How to Maintain and Clean Your Custom Signs for Longevity

Custom signs are an important investment for your business – making a lasting impression, guiding your customers, and showcasing your brand. Keeping your signs looking their best is essential to maintain that professional appearance and ensure they last for years. Proper maintenance and cleaning are key to longevity, and with a little care, you can extend the life of your signs while keeping them vibrant and appealing.

Check out these guides and tips to help you maintain and clean both indoor and outdoor custom signs:

1. Regular Inspections Are Essential
To keep your signs in prime condition, make it a habit to inspect them regularly. Look for signs of wear, damage, dirt buildup, or fading colors. For outdoor signs, check for weather-related damage, such as rust, cracking, or peeling, as well as any bird droppings, debris, or dirt. Indoor signs may accumulate dust or fingerprints, which can dull their appearance.
Tip: Set a monthly reminder to inspect your signs and catch small issues before they become bigger problems.

2. Cleaning Outdoor Signs
Outdoor signs are constantly exposed to the elements, including rain, wind, UV rays, and pollution, which can lead to grime buildup. Proper cleaning is necessary to preserve their appearance and functionality.

Step-by-Step Cleaning Process:

Remove loose dirt and debris: Start by gently wiping the sign with a soft, dry cloth or using a brush to remove dirt, leaves, or other particles.

Wash the surface: Use a mild soap solution (mix a small amount of dish soap with water) and a soft sponge or cloth to clean the surface. Avoid harsh chemicals, abrasive sponges, or pressure washers that could damage the finish or graphics.

Rinse thoroughly: Rinse the sign with clean water to remove soap residue, and use a dry cloth to wipe it down. Protect against the elements: Consider applying a UV-protective coating to guard against fading from the sun and prevent moisture damage.

Tip: Clean outdoor signs at least twice a year, or more often if they are in high-traffic areas or exposed to pollutants.

3. Cleaning Indoor Signs
While indoor signs are protected from harsh weather, they can still collect dust, fingerprints, and smudges that diminish their appeal. Cleaning them regularly will keep them looking professional.

Step-by-Step Cleaning Process:

Dust the sign: Use a microfiber cloth or feather duster to remove surface dust.

Wipe with a damp cloth: For stubborn marks, use a cloth dampened with water or a non-abrasive cleaner specifically designed for delicate surfaces. Make sure to test any cleaner on a small, inconspicuous area before applying it to the entire sign.

Dry thoroughly: Use a clean, dry cloth to wipe off any excess moisture.

Tip: If your sign has intricate details or is made of sensitive materials, consider hiring a professional cleaning service for regular maintenance.

4. Protect Your Sign from Environmental Damage
For outdoor signs, investing in weather-resistant materials can significantly extend the life of your sign. Aluminum, acrylic, and high-quality vinyl are excellent options that resist rust, corrosion, and fading. If your outdoor sign is subject to intense sun exposure, placing it in a shaded area or using a UV-resistant finish can protect it from fading over time. Temporary signs such as banners, a-frames and flags should be taken down before bad weather and at the end of each day to prolong their life. Temporary signs are not designed for rugged outdoor weather or long-term exterior use.

For indoor signs, avoid placing them in direct sunlight to prevent fading and discoloration. If your sign is near doors or windows where sunlight can reach, opt for UV-blocking window treatments.

5. Repainting or Refinishing as Needed
Over time, signs may fade or lose their original shine, especially outdoor signs. Repainting or refinishing them can restore their appearance and keep them looking fresh. This is particularly important for wooden or metal signs, which may require touch-ups or sealing to prevent weather damage.

Tip: Schedule refinishing every couple of years for outdoor signs, and sooner if you notice peeling or fading.

6. Proper Handling and Storage
If you need to remove your sign for any reason—whether to change locations or during a renovation—ensure it is handled with care. Use gloves to avoid smudges or fingerprints, and store it in a cool, dry place away from direct sunlight and humidity. For signs that are stored long-term, wrap them in protective material to avoid scratches or dents.

7. Know When It’s Time for a Replacement
Despite regular maintenance, signs will eventually wear out. If your sign is heavily damaged, faded, or no longer represents your brand’s style, it may be time for a replacement. A new custom sign can give your business a fresh look and ensure you continue making a strong impression.
Regular maintenance not only enhances your brand’s image but also protects your investment, ensuring your signs remain a valuable asset for years to come.
