Do you have yellowed brick and wish to restore it to its original color?
I recently stumbled upon a Maker Magazine article called “Un-Yellow Old
Plastics - Retr0brite!”

Yes. I tried this last week and the results were very good. Take a look at this
post.
The picture shows the results before and after a exposure of only 2 hours in the
sun. We are having a heat wave here in Brazil and I was afraid of letting the
bricks too much time in the sun and in the end get some melted bricks.
My main problem is to find the liquid Hydrogen Peroxide 10%. I can only find it
in a creamy base that is used to bleach hair. This makes it difficult to apply
to bricks.
I looked at the surface of the treated bricks and couldn’t see anything
different from a new brick. So, it seems that this process is safe.
But, will have to do some more tests as well.
Leg Godt,
Ildefonso.
