How To Clean Aluminum Bleachers

Considering all the people, hot dogs, and sodas that come through a set of grandstands each year, they eventually need to be cleaned! However, cleaning an entire set of bleachers can be a challenge. 

Continue reading to learn how to clean a grandstand thoroughly and efficiently!


Use mild soap and hot water

Because the seats and risers of aluminum bleachers are anodized, they are more durable and corrosion-resistant. Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, anodic oxide finish. 

This allows most stains and spills to be cleaned up with regular soap and water. It also stops oxidation staining from happening on the bleacher planks.

Pressure washing speeds up the process

To clean a full set of grandstands in less than a week, it is smart to get a team of volunteers, all with pressure washers, to help out. 

The best pressure washers to use to clean aluminum bleachers can run hot water and have high psi. The pressure, heat, and mild soap will clean up any gum, mud, or stains from the weather easily.

What not to do

Do not use a caustic cleaning agent to clean your bleachers. You might consider using something caustic to clean up grease or dried gum, but if it isn’t rinsed off properly it could cause burns and rashes to attendees. 

Also, if a caustic cleaning agent wasn’t rinsed off properly  and it rains, it will be like walking on ice, causing a slip hazard.


Hire contractors

If you don’t have enough time to pressure wash, leave it to the professionals! 

Just search for “pressure washing company near me” and you should be able to find 3-5 residential pressure washing companies who would love to develop a quote your grandstands. Most pressure washing companies can thoroughly clean a set of grandstands within a few days.
