If you have considered purchasing new coroplast signs or you have already invested in a brand new set, one thing is certain: maintaining your new signs is essential in ensuring a longer lifespan and a better use of your signage budget.

On construction sites, exposure to extreme weather, dirt and equipment can make the coroplast signs lose their shine over time. Some of the messaging may even get lost under the buildup, putting workers and visitors at risk if the signs are not immediately visible. The good news is that cleaning and maintaining coroplast signs is easy and doesn’t require a lot of time. Keeping your new signs clean can prevent heavy build-ups that can cause long-term damage.

Here are some tips on how to clean your coroplast signs.

Tip #1: Cleaning solution

Choosing the right cleaning solution is important since the wrong substance can damage the graphics and the coroplast itself. If you are looking for an inexpensive solution, water and a simple dishwashing soap is the best way to go. When cleaning coroplast signs, it is best to avoid anything stronger as it can erode the material over time.

Tip #2: Cleaning cloth

A store-bought microfiber cloth is highly recommended as it doesn’t leave any residue behind. Alternatively, a sponge or cotton towel can also be used although you may find that they will leave streaks.

Tip #3: Cleaning techniques

We recommend using a sponge or a squeegee as it doesn’t leave any residue behind. If using a dishwashing soap, make sure to wash in the direction of the corrugation, rinse properly and allow to air dry. Depending on season, we recommend cleaning your signs every 1-2 months to keep them looking shiny and brand new.

Tip #4: Storage

Store in a cool place, avoiding direct sunlight exposure or excessive heat. To prevent bending, do not stack heavy materials on top. When cared for properly, coroplast signs can last for up to 3 years.
