Anyone know any tricks for reducing the yellowing in older PVC window frames?

[cycosis]

Were in the process of repainting the interior of our home and were noticing some significant yellowing in our interior window frames. All ive read is that vinegar can be used to clean them, but nothing that overly helps in reducing the yellow/ whitening them.

Any had success getting their older frames more white, aside form painting them too?

Could try hydrogen peroxide.

Never used for this specifically but used for rubber on my car, restored it to almost new. Also used to remove some oxidation or fade on carbon fiber parts.

There's also some other products from meguiars that might work. Surprisingly, it's the RV and boat line you're after.

Use this on sneakers all the time. It doesn’t clean the yellow. It chemically reverses the yellowing process. Chemistry lesson: https://medium.com/@pueojit/a-look-i...s-db14b646e0ad
