Yes, you can safely pressure wash your railings. Most railings are aluminum, which is durable enough to handle pressure washing without damage.
- It’s a good idea to use a rag for wiping them down as part of regular cleaning.
- Be cautious around the bases of the posts. The small “beauty caps” that cover the screws can easily be blown off by high pressure.
So while pressure washing won’t hurt the railing itself, just be mindful of those caps during cleaning.
