yellowing plastic trim

Superclean.

Check out this thread I posted a year ago about the same problem. Be prepared for a few naysayers who have not tried it to tell you that it won't work or is bad because its bleaching the plastic (its not)...blah blah blah. My plastic still looks brand new.

It IS "bleaching" as in whitening a surface and the surfaces I frequently use hydrogen peroxide on are natural textiles.

Hydrogen peroxide is an acetic acid and lemon juice, a milder one.
However "Hydro p" should not be confused with chlorine bleach commonly called Clorox in the US market place or oxygen bleaches such as OxiClean and powdered bleaches in general.

I would not be surprised to hear that it works to remove yellowing from plastic if the item soaks in a solution long enough. Probably adding washing soda or powdered bleach to the solution would help as well.

Big problem with any liquid whitening agent is to keep it from dripping off before the chemical reaction is completed on vertical(?) surfaces. For them, you buy a lot of Pampers, soak them in the whitening solution then tape them to the surface.

I suspect the original thread's disconnect came into play regarding the 2 different meanings of bleach: scientific and everyday usage. Both defines are right just if different ways;).

HTH

The best and longest lasting fix is a plastic-specific spray paint.

That didn't take long....heres an article, one of many, that explains the chemical process taking place. This one is fairly basic but does a good job of explaining it. This is a chemical stabilization process (bromine stabilization).http://www.mountainouswords.com/mountain-air/retr0bright-restoration-project/

I understand what you mean when you refer to it as 'bleaching' (in a generic sense) but that process can be damaging and this shouldn't be confused with that. None of the papers explaining it use the term 'bleaching'. Semantics I guess.

I just agreed with you:h

Yeah...just saw that last line as I was editing my previous post...we agree...I'm just a step behind your posts! :)

I have had good luck with acetone to remove the yellowing from plastic trim and panels. It even removes mold from the plastic bead trim and caulking. It is a solvent so don't saturate the cloth or let it soak on the part you are cleaning just dampen the rag and wipe it off.

I use Clorox Kitchen Cleanup with bleach. Spray it on, go have a cold one ... or 2, rinse. Also works well on the AC outlet covers and grab handle next to the door.

That works but for more stubborn yellow stains I have used Softscrub with bleach. It takes a little work but will remove the yellowing.

I had never heard about Softscrub so I did a search. Looks good. THANKS!
