What is the risk of removing the lock and window crank on my Andersen casement windows from 1970 when repainting them to clean and possibly paint them?

I’m in the middle of repainting my windows and thinking about taking off the lock and window crank to clean and maybe paint them. But I’m a little nervous about the window falling out if I do. These are Andersen casement windows from 1970, so I want to be careful not to mess anything up. Any advice? 😅
It will be easier to paint. Before that, remove the crank which has a tiny set screw. Next, remove the cover.
Your window isn’t going to come loose
I haven’t come across those rolling windows in years
Haha, everything will be alright.
Avoid painting them as it may ruin their appearance. Instead, remove them, clean them, and then reinstall. You can also purchase replacements from Andersen if necessary.
The original coating is starting to wear off, so it’s time to refinish them or they will look pretty bad. It would cost close to $1000 to replace all the hardware on my windows, so I’ll try painting them instead.
Definitely go with either Rustoleum or Krylon spray paint. Make sure to let it dry for two to three days before putting everything back together.
You have the option to fully remove these mechanisms. Anderson windows are among the easiest to remove and replace. If you plan to repaint multiple windows and are removing all the hardware beforehand, I recommend labeling each piece. Numbers or letters can work. Match Mechanism A or 1 with Window A or 1, and so on. Different window sizes may require different mechanisms, some for Right or Left Handed openings. Taking photos and labeling before disassembly will be helpful during reassembly. For painting, consider using automotive spray paint. Lightly sand all surfaces with steel wool, clean thoroughly with a degreaser like white gas that leaves no residue. Use a self-etching primer before the finish coats, applying several light coats in a well-ventilated area. A clear coat can be applied as well, but avoid getting paint on the mechanisms or splines for the handles. Alternatively, contact Anderson windows for replacement mechanisms using the reference part number found on the mechanism. Best of luck.
Hey , I really appreciate it! Your help was so thorough and valuable
I have to say, that is one of the most helpful responses I’ve ever come across. So positive, so helpful, so polite, so well-explained, and so encouraging. If only everyone offering “help” could take notes from that.
Be cautious when removing them. The wood around the hardware might have expanded over time and is quite thin and soft. Cut around the edge with a utility knife. If desired, use spray paint in very light coats. Avoid using trim paint.
You may even come across some replacements on eBay or a similar platform.
