Does Aluminium Rust? Managing Aluminium Corrosion

Category: Blog, Service & Maintenance, Tips and Tutorials

Aluminium frames are well known for being strong, reliable and corrosion resistant. While Aluminium is certainly more resistant than most metals when it comes to corrosion, if not maintained regularly, the risk of corrosion can increase.

Research on Aluminium corrosion conducted by both Curtin and Monash Universities shows that corrosion has nothing to do with the quality of the aluminium or installation, but the environment it sits in.

The studies showed that chloride salts can accumulate in the crevices between both the dirt deposits along the frames and the space between the brickwork and aluminium, which can cause corrosion when combined with moisture.

These crevices can be hard for oxygen to reach, increasing the risk of chloride corrosion as the Aluminium cannot form its natural protective layer. These spaces stay wet for longer, furthering the effects of corrosion the longer they are left alone.

The good news is, there is a way to prevent this from happening!

By regularly cleaning your aluminium door and window frames, you not only maintain their look but also increase their functional life by helping to prevent corrosion. It’s also important to try and limit any water from your pool or sprinkler system getting into the space between your frames and the bricks.

Here is a step-by-step guide on how to clean your Aluminium frames safely and effectively:

Using a screwdriver with your cleaning cloth can help you clean those hard to reach frame tracks

  1. Make sure you have removed all watches, jewellery, and other valuable items. Put on some gloves to be safe too!
  2. Jason Windows recommend that you use clean, warm soapy water to clean off any residue. It is recommended you only use commercial cleaners or solvents on extremely stubborn marks or residue. Harsh chemicals can potentially have an impact on the finish of your frame.
  3. Use a non-abrasive sponge or cloth for both washing and drying. This is because the use of mesh or other abrasive material can scratch the metal.
  4. Make sure to clear all dirt and residue out of the tracks and sills. Dirt in the sills can potentially cause damage to rollers, drop bolts and guides. Clean your sills by spraying the warm soapy water and wiping them down. Use a pointed object such as a screwdriver to ensure you reach the bottom of the tracks.
  5. Ensure that weep holes are also kept clear for proper drainage and leakage prevention.
  6. Spray a touch of silicone spray to finish.

 

How often should I do a preventative clean?

How often you clean your frames should depend on your environment. For example, most residential areas allow for a clean every 6 months. However, if you live in coastal areas or have frames in close proximity to a swimming pool, you should be cleaning your frames every 3 months.
