I'm wondering how to remove old masking tape residue. My wife collects antiques and a plastic object she got has some masking tape residue on it from a long time ago. I need to get the residue off without damaging the plastic. I'm thinking I need to soak it with something like paint thinner or WD40. Something like Acetone would probably harm the plastic.
Things like Goo-Gone contain a citrus solvent called d-limonene. It's good for removing things like tape residue, but would require a high dwell time before it would mar plastics. It's still a good idea to try the weakest product first, like baby oil. Baby oil, and even vegetable oil, while mild, have a good reputation for removing masking tape residue.
I'm with batterycharger on this one. I got some bubble gum on the lower plastic cladding of my car (and being an OCD ish clean car freak) I used some Automotive International car solvent, smells a lot like a bug and tar remover/lighter fluid/naptha I had (used it because well, I had it on hand.)
I always follow up with a pH balanced soap. (and on a car with wax.)
Ok, this is an easy one for me. I use car wax (I use the liquid carnuba type). It works perfectly, and it works VERY easily. It doesn't make a mess either. I just dab a bit on a cloth (even a paper towel will work) and rub the adhesive remains. I've used this method so many times and am always happy and pleased that I made the discovery.
BE CAREFUL!!! If you are using cleaners on antiques or collectibles, you can easily remove the finish and very seriously decrease the value of the item. How seriously? By as much as 75%.
Valuable items require professional advice or work. Removing adhesives can be very, very tricky stuff. The solvents that remove the glue can very quickly damage the finish or the actual object.
Even if these are things she is going to turn around and resell, why lose money?
Contact an antiques dealer in the area and have them recommend someone to talk with. If you can't find anyone, check with one of the bigger libraries in the area and see if they have a conservator or preservation specialist who might be able to recommend information.
I used to work in a research library and my mother collected a wide variety of stuff. Ah, the crap, er.. valuable knowledge you learn and remember over the years...
Vegetable oil is very safe but slow acting. It will remove the masking take goo. If you use a solvent it will surely destroy whatever is under the goo. What you need to to loosen the binders holding the goo to the base.
Example: I had a guy with an 'internet emergency' once. He had just spilled bottles of enamel paint on his family's cherished family table. What a mess it was. People on the net were screaming to get laquer thinner to clean it up. I knew better so I begged him to go to the kitchen and get vegetable oil, liberally pour the oil on the paint mess, then clean with a lots of rags. Luckily he listened to me and the table was fine. When his parent got home they were so impressed that their son polished their antique table. [img]/ubbthreads/images/graemlins/wink.gif[/img]
After oiling OOOO steel wool could be used to help the goo come off.

Use a bit of new masking tape to lift the residue off. Tape it on lightly n reuse the same section until its no longer sticky. Use another part until all gone.

I was going to make this suggestion too.
I work in a calibration facility and we have all kinds of stickers on our instruments that have to be replaced after a new calibration. I have tried most of the items listed above. Good ol' masking tape usually works for just about everything. I usually just unwind enough on the roll that I can rewind it backwards onto itself. You end up with a roll that is sticky on the outside. Poke your hand in the middle and rock it back and forth over the stuff you are trying to remove.
