How Should I Maintain My Sliding Glass Doors?view of yard house and sliding patio doors

Sliding glass doors do require care and upkeep that some people find bothersome, but in our experience, it’s better to put in a small amount of money upfront than wait until there’s a problem. Most people will agree that the time and money spent maintaining your sliding glass doors will pale in comparison to the money and time you’d spend on repairs. Sliding glass doors only have a few components. It’s best to take care of the, in the following ways: 

  • Keep the tracks clean and clear of debris.
  • Depending on the climate, use an aerosol-based wax spray or a non-stick silicon-based lubricant on the tracks.
  • Use weather-stripping on your sliding glass doors.
  • Keep locks well lubricated.

How to Avoid Rust

A mixture of dish soap and baking soda is an excellent cleaning solution for sliding glass door parts. Use a small brush to gently scrub the mixture into the metal, let it sit for ten minutes. After that, pour vinegar over it and scrub at it with a brush until clean before wiping the mixture away. This process can help remove some of the rust and caked-on dirt.

Our Prestige Vinyl Patio Doors are tested against the most stringent industry standards for air and water infiltration, wind-loaded resistance, ease of operation, forced entry and much more. This means you’ll have lower heating and air-conditioning costs, easier cleaning, low maintenance and increased comfort.
