If you have considered purchasing new aluminum 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 aluminum 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 aluminum 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 aluminum signs.

Tip #1: Cleaning solution

Choosing the right cleaning solution is important since the wrong substance can damage the graphics and the aluminum itself. If you are looking for an inexpensive solution, water is the best way to go. However, be aware that water may leave unwanted streaks. Other simple options include glass cleaners or rubbing alcohol that will clean the build up without leaving any streaks behind. When cleaning aluminum 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 tips

For best results, use a spray bottle to avoid over saturating the cloth and work your way outwards from the middle of the sign. Depending on season, we recommend cleaning your signs every 1-2 months to keep them looking shiny and brand new. When cared for properly, aluminum signs can last for up to 5 years.
