How do I remove adhesive? 1935 Nebraska plates

I have a set of NOS 1935 Nebraska license plates that were stored in the original envelope w/a piece of plastic between them.Over the years,the plastic degraded and now the plates have plastic melted to them.I tried to remove some of it(on the back) with Greased lightening.It took the paint but no plastic.Dish soap did nothing.Any ideas?Will someone please post pix for me [email protected]

 

Might not work on your plates, but WD-40 removes adhesive.

 

I wish i could help you..I have a simular problem facing me this summer.
the PO of my Tudor Glued the top vynl on the roof with liquid nails

 

Maybe soak 'em in hot water with mild dish detergent.

 

if your going to repaint them (since it took the paint on one try) id soak them in lacquer thinner, that stuff will take anything off!!

 

How about a 175 degree oven for a little while to get them unstuck.

 

Goo Gone. Don't know how it affects the surface of the plate so maybe try a small drop in the corner, but it's worked great on some other painted surfaces I've used it on.

 

Prep sol or 3m adheasive remover is pretty mild, I sometimes use it after taking off vinyl graphics

 

There are some non-toxic adhesive removers based on citric acid, available at any major hardware store, that should do the trick without harming the paint.

 

I've removed stuck on masking tape by soaking it in oliver oil. Don't know if that will help,but it won't harm your plates. Good luck. If you find something that works-post it during tech week.More folks will read it,

 

I would go with the WD40 idea. I have removed bumper stickers with it. will not damage paint.

 

I've always had good luck with the 3m stuff...

 

Gooo gone is the shit. I belive its made from natural orange souls. So might be pretty gentile in theory.
