How do you deal with yellowing plastic on NES/SNES decks? Paint?

[walterg74]

My SNES was only yellow in the rear on both shells. It cost me $3.00 and one day with disassembly, retrobright application, cleaning, drying, and reassembly. I purchased a 32 Oz bottle of 40 VOL peroxide creme from Sallys Supply. It worked the same as the official retrobright recipe.

 

Hi, would you mind telling me if it was any particular brand or link to the product?

 

Thanks!

Thanks! Did you use it "pure" or mix with/add anything? How exactly did you apply it.

I applied it pure with a tooth brush and then covered with plastic wrap to keep it from drying out.

I was too. I did read also that extreme heat can cause the yellowing process even if the item is stored in the dark.

 

This is definitely true... I have loads of old monitors that have that "piss yellow" color from getting hot. Nasty color.

I forgot to add to be sure to wear latex gloves when applying. The peroxide can cause mild skin irritation, but nothing serious.

Thanks, will try it out and see what happens!

I could see the NES plastic being restored, but I've just not seen results with SNES that are satisfactory to me. SFC I would see it as well, but the SNES nope. I think it's partly due to the shade of white/grey it was, very light, or the texture of the plastic, but nobody ever gets it properly. Using a vinyl die is great and all, but I can't see how you could get the original color without extensive mixing.

I was lucky that my Snes was not yellowed that bad, so it took me only one attempt. Everything that I have read on the web indicates thank you need to treat multiple times to completely restore the original grey color. Edited August 24, 2015 by Oldschool80skid

Eh, even then the results seemed way too white if you ask me.
