1. Clean your aluminum windows carefully

As the aluminum window is the same as the wall, it blocks sand, dust, acid rain, pollution, etc. So a lot of sand and dirt will be deposited on the surface of the aluminum frame and the groove, especially the aluminum sliding window with mosquito screen. Firstly, you need to clean up the dust and make sure there is no debris, so as not to wear your frame in the subsequent cleaning process.  

Then, use clean water or a neutral detergent to clean or wipe the frame and the adhesive strips to remove obvious marks and dirt. This can ensure that the aluminum window coating is less likely to fade, and the adhesive strips are less likely to fade, hardening and cracking.

Warmly reminder: The longer the mark on the window frame, the more difficult it is to remove. So we recommend cleaning the windows at least once every three months.

2. Remove oxidized spots

● Pour equal amounts of water and white vinegar into the bucket, and apply the solution to the oxidation point to decompose the mineral deposits. 

● If the white vinegar cannot clean the dirt, use a knife to gently scrape off the aluminum rust, then wash it with soapy water, dry it with a dry cloth, and polish it with a dry cloth after waxing, and it will be as smooth as new.

The lubricating oil can be used to lubricate the hardware rotation, sliding, and locking points. After dripping the lubricating oil, you need to open and close 3-5 times, so as to increase the flexibility and service life of the hardware rotation mechanism.
