GLOVES and protective GLASSES
a canister HYDROGEN PEROXIDE commonly called WATER OXYGENATED
A container or glass jar
The light, the Sun to accelerate the photo-synthesis effect
Time to go to Casto to buy his miracle product!

In addition, hydrogen peroxide does not attack the red paint of the body of the bumper.
I attached a link for those who would treat larger plastic parts:
Today it is not beautiful, I'll drink myself a foam until the sun returns.
