"Do not use solvents on electronic equipment"

What about George Best?

Anything which removes labels or the glue they leave behind is of interest to me! Do you know what Goof-Off's active ingredients are ?

Mostly xylene.

Another label/glue remover is "goo gone". The above database lists its ingredients as "proprietary or trade secret", but IIRC it's orange scented naptha.

The Allsop CD Strong Box:

The vast majority of CD (music, ROM, or otherwise) jewel boxes are polystyrene, including the half-thickness jewel cases. Some music CDs come with a clear center insert.

Don't know, but the product is a bout 3.00 a pint at my local Home Depot. It will burn your skin pretty well if you leave it on for a while. I used it once to remove tar off my fore-arm, and I won't do that again.

Neither are good for removing labels affixed to plastic surfaces.

Perfect, thanks!

Jeez, dude (edited, was dipshit). Google is your friend. A simple search on "Polycarbonate CD Cases" yields hits galore!

Most likely limonene (although you'd probably be able to smell that chemical over a solvent, whatever the mix). Used in any "orange" cleaner product, and evidently, suprisingly effective, considering it comes from orange peel.

Moron, there are *thousands* of different "plastics". Such an absolute statement shows what a complete moron you are! BTW, Goo-Gone works fine on many plastics, including melamine.

What a frappin' moron!

Could be. They advertise that it's "orange", but I'm not convinced. It does work, though not as well as other solvents.

From the shit you spew in these groups, you have been huffing the crap for years.

Why don't you try snorting some, DimBulb. It might clear up your head! What a maroon! ...and everyone here knows it.

CAlling Roy that is an insult to maroons everwhere! ;-)

Hammond Mfg, in your own country, in fact :-).

I've used some of the transluscent and some of the clears and was very happy.

I think some of the NEMA-rated boxes are polycarbonate too.

I have alswys liked to use spray furniture polish for optics. I beleive it contain silicon and this leaves a very fine (effectively optically transaprent) film which is also grease resistent.

RainX is better.

I use BBQ lighter fluid on plastics, with great results. No damage of finish or paint. Best to test a inconspicuous space first, of course.

Alcohol is one of the more innocuous of the organic solvents. I doubt that it would attack any plastic case, but other solvents can. One thing that alcohol can do is dissolve the labelling ink on some circuit boards or components. This would make repair (i.e., replacement based on the component value or board number) difficult, maybe dangerous if it happened that a lower-voltage component were substituted, for example, because the original component's label had become smudged or obliterated. Solvents might dissolve the lubricant on switch contacts, or sliders, or disperse it over potentiometer tracks causing later problems. Spraying solvent into equipment may damage speaker cones or piezo speakers.

Liberally dripping solvent into equipment may cause it to malfunction, e.g., an air-gap capacitor trimmer will have different parameters when the dielectric is liquid solvent, and if the solvent is flammable it might cause a fire from static electricity or a switching spark. If a cleaning solution were to leave an hygroscopic residue on a circuit board this could initiate electrochemical corrosion (copper/brass + lead/steel/ aluminium in contact in a conductive solution). Water-based cleaners with ammonia will be conductive, so could short out tracks on a board.
