Yes, it can be do done.

I recently learned that yellowed plastic of any color can be brought back to it's original color. In my online research it seems the best method would be to go to a beauty salon store and purchase 40% hydrogen peroxide cream. Att you have to do is brush the cream on the plastic, and either leave it in the sun, or put it under a UV light for a few minutes. This was developed to bring old computer casses, and keyboards back to looking new again. Other videos i watched showed testing on colored plastics. One point to remember is the difference between UV yellowing, and cooked plastic. Obviously this does not work on plastic that is cooked, and a little brittle. Hopefully someone with a classic caddy, and a discolored interior might find this helpful. Obviously testing it out on a sample, and removal of the plastic would be recommended to get he best and safest fix.

Hi winterset, what plastic are you speaking of? Interior, exterior, dash, any photos? Do you have any solutions for oxidized black plastic? This is good to know, thanks

I do not have any photos. The fading i was referring to was that yellow (looks like nicotine) discoloring that happens to old plastic appliances (computers, telephones, and plastic in cars like glove compartment, seatbelt hardware etc. in older cars). If you are talking about weathered black plastic, i found as seen on tv-"Detail Doctor" "instant restorer" works pretty good if you apply a light amount, then rub it in. I also use maguires tire shine on black exterior plastic trim. I think black plastic is alot easier to bring back to life than white or gray plastic because the black hides the yellowing. Also, if anyone has white rubber trim on their car, this peroxide method will probably turn it white again too.

Btw, the detail doctor smells like a cake baking in the oven. Not sure how it got such an unusual smell. My kids always know when i use it.
