Aluminum windows are getting hard to open and close

Question

We have aluminum windows and have had them for about ten years. All of a sudden they have started squeaking and getting a bit harder to open and close.

Any suggestions would be appreciated.

Answer 1

The easiest way to handle this is with Vaseline...when it gets dirty, wipe it off and apply a new coating...WD40 has to be replaced too often. Many people use a bar of soap to lube up aluminum, but Vaseline does a good job. Your aluminum has corroded (normal)...you can remove windows and sand with fine sandpaper, sand the track at the same time, then apply Vaseline and they will work like new again. Goldwing

Answer 2

the Alum is oxidizing

spray the slide with Pam,[cooking spray]  or use spray wax,  pam will last longer,

it will lube the slides.

Answer 3

AVOID graphite.

It ends up getting all over everything and never comes out.

How about a small bit of WD-40 onto a paper towel, run it up and down the channels?

Answer 4

  If you can remove the first window from the track and on the bottom you should be able to see if the window as rollers or just small plastic guides on it. What ever you do Don't use any kind of oils or grease on them, this will cause them to collect dirt and make it worse. Go to a local window repair shop if there are rollers or guides and have them replaced. Aluminum windows usually do on the windows that you are talking about. I hope this help you out.
