Remove Scratches From Your Deck’s Aluminum Railing And Keep It Protected

Your deck's aluminum railings can easily become scratched after being exposed to the elements. Remove these scratches and give the railing a fresh appearance with some simple methods. Once the railing is restored to its original condition, protect if from becoming scratched in the future. 

Use The Following Materials

  • sandpaper (various grits)
  • hand sander
  • water
  • mild detergent
  • aluminum polishing compound
  • buffing cloth
  • lint free cloths
  • aluminum sealer
  • railing cover

Clean And Sand The Railing

Remove dirt and debris from the railing with soapy water and a lint free cloth. Dry the surface off with another cloth. Inspect the railing to locate all of the scratches. Dampen a piece of fine grit sandpaper with water and add a few drops of detergent to it. Damp paper works best, because it will provide enough lubrication so that the paper moves smoothly along the railing's surface. Attach the paper to a hand sander.

Run the sander firmly over the scratched areas. Check periodically to see if the scratches are fading. If they aren't, use a more coarse piece of sandpaper. Sand the aluminum until the scratches are gone. 

Polish The Aluminum

Apply a small amount of aluminum polishing compound to a buffing cloth. Rub the compound on the railing's surface. Add more polish to the cloth if needed. Continue polishing the aluminum until it has a reflective surface that shines. Dampen a cloth with water and wipe the railing's surface so that any compound residue is removed. Dry the surface with another cloth. 

Protect The Surface

To prevent scratches from appearing in the future, apply a coat of aluminum sealer. This product can be found in home improvement centers. Apply an even coat with a clean, lint free cloth. Once the product has been rubbed into the surface, the railing will have the protection necessary when subjected to adverse weather conditions. Reapply polish to the railing when it becomes dull. When you add the polish, make sure to apply a new coat of aluminum sealer as well.

You can also purchase a railing cover to protect the aluminum. Many cover styles are preformed and can be quickly wrapped around the railing. Measure the diameter and length of the railing on your deck and bring this information with you to a retailer when you are ready to purchase one. Taking good care of the railing will give it a beautiful appearance and will prevent future damage.
