Woodstock plastic yellowing

[db (martinez, ca.)]

I came across an article on ABS yellowing and remembered that this has been a question here. The solution, using 15% hydrogen peroxide may be worse than the disease though. If this info is already here, let me know and i'll delete this.

You could try Retr0bright. I've used it before with success. It uses hydrogen peroxide but in lower concentrations.
