Title: Peroxide Treatment on Beige?
Post by: WEBellSystemChristian on June 06, 2015, 11:09:12 PM
I want to try dis-discoloring (as if that was even a word!) beige hard plastic, in other words, removing the discoloration from beige ABS. I know it's worked on light blue ABS for me, but I don't know about beige. Have any of you had results with it?

Yes, Beige and White seem to work best!

Good!

I'm giving a badly faded test cap the peroxide treatment right now, and it hopefully will look good in an hour or so.

I usually leave my stuff out in the sun for 6 to 8 hours! How much will actually happen in an hour?

I use an actual UV box my dad and I made. It has four UV bulbs and is lined in sheet metal inside. It really quickens the effect of the reaction, so the defading process is much faster than it would be in the sun.

After only a couple hours, the cap was almost perfect color! It was originally very faded!

Ok, that makes sense. Concentrated UV would be much faster.
