Permanent marker removal help? (White textured plastic)

I mentioned this in my 360 mod/paint thread, but I figured I'd ask officially:

Does anyone have any magic tricks to get old, soaked-in permanent marker off/out of textured plastic?

I have tried:

-unknown isopropyl alcohol
-9X% isopropyl alcohol
-lighter fluid (naphtha) (I used this to remove -most- of the marker initially, but there's still a shadow of it left)
-turpentine
-lacquer thinner
-Mr. Clean Magic Eraser (ruins the original texture of the plastic, and doesn't work)
-WD-40
-"dry-erase marker trick" (writing over it with dry erase marker, then wiping it away - leaves dry erase remnants in the plastic)
-brake fluid (for a car) (surprisingly didn't seem to harm the plastic, but didn't provide any results either)

I am thinking the ink remnants are just too deep in the plastic pores and nothing is going to remove them without harming the plastic.
Note: Acetone will "remove" the marker, but attacks the plastic enough to change the texture significantly (I tried this on a tiny spot).

I haven't tried things like hairspray (and many other "home remedies") because I figure the only reason that would work is due to an alcohol/ethanol-based solvent, which I doubt is much different than the alcohols I have tried. I'm pretty sure all of these "home remedies" listed all over the internet are just random alcohol-based liquids that one might happen to have sitting around.

 

Goof Off, try that. It did work on mine but it really stinks so do it outside if you can.

 

I need to try that Goofoff. I have some similar problems

 

Went to the store yesterday and looked at Goof-Off.

Unfortunately the ingredients it lists are Acetone and Xylene. Basically smells like a weird acetone. Not surprisingly, an inconspicuous spot test had the same results as pure Acetone - eats the plastic enough to make a difference.

 

have you tried retrobrighting it?

 

Oops got that 2 crossed -_- Sorry my bad

Goo Gone.

 

Ah, Goo Gone. I'll try it.

 

Your technique may be part of the problem, the best way is to hold your cleaning cloth with your thumb. Press hard and twist, this will often get the grime out recessed letters and markings too.

 

Easy to remove.

Use either some cooking oil, and wipe it off with a towel. Not sure if eucalyptus oil is sold where you are, but also try that, removes a lot grime for me.

 

Cooking oil. Never heard of that one. I'll have to give that a try

 

Just don't go over board as it can seep into places you don't want. Best way to do it is with a paper towel and apply to the surface, then remove it with a tea towel or hand towel.
