How To Ensure Your Aluminum Shower Doors Are Clean and Rust Free


Painting aluminum shower doors prevents them from rusting by providing a hard coat of paint.  Paint helps protect metals by creating a protective layer between them and oxygen from the environment.  This avoids oxygen in the air from reacting with metals and causing them to rust.  This prevents water from reacting with the metal and causing it to rust.

Regular Cleaning

Regularly cleaning the shower doors will help to prevent mineral deposits and soap scum from building up on your shower door and causing them to oxidize.  Immediately after each shower, apply car wax to the shower door to keep it from rusting.

You can apply other maintenance tips to prevent them from rusting.

  • Wipe your shower doors every time you’re done taking a shower.  Water is one of the critical elements that cause rust to form.  If your shower doors are regularly cleaned, there are low chances for corrosion.
  • Use a rust-resistant seal on the exterior of your shower door.
  • Check for proper ventilation in the bathroom.  Poor ventilation can cause rusty shower doors.
  • If you plan to install shower doors on newly constructed bathrooms, ensure the bathroom’s overall design is flawless.  If your shower door is not properly designed to allow for proper drainage, it may aggravate the problem.
  • Avoid exposing the shower door frames to acidic or alkaline water.
  • Choose to have your frame anodized.  This protects the aluminum product from corrosive elements while also improving its appearance.
