    Naptha has been banned around here for about twenty years, along with other conspicuous smog-formers. Staggering quantities of related chemicals were once used in the area. The regulation has nothing to due with human heath and carcinogens (which is the responsibility of the EPA), but with
    smog per se, per Calif Air Resources. If you don't like these regulations, then you can always move
    to Bakerfield or Houston and cough and wheez.

    The visible smog bowl was only 4 or 5 years ago.

    GooGone is 80-95% light petroleum distillates, the current version will disappear too.

    GooGone and 99% IPA will both leave residues. There really isn't a substitute since the exact property you desire (complete evaporation without residue) is exactly what they are banning. Send your thoughts to the South Coast Air Quality Management District (http://www.aqmd.gov/). Theoretically they report to elected officials and should respond to your inquiries.

    I first flew into LA in 1959 and from the airplane you could see a pink smog dome. In fact, the pilot pointed this out to us passengers. So, that smog dome is appreciable and has been there for nearly 1/2 century.

    As for residues, only pure hydrocarbons can clean without residue! Others may work but may leave a residue. Residue is often unimportant with solid state devices, but residue is critical when working with devices that have moving parts. And so, you have to take that into consideration with camera equipment vs electronic equipment.

    "Bestine", usually found at graphic arts stores is very clean heptane - an excellent solvent/cleaner. I've used it as cleaner without seeing residue, and also as an extraction solvent.

    Update -

    I was in an art supply store today (in California) and, lo and behold, there was naptha back on the shelf. An employee told me that California art supply stores can now legally sell naptha again due to pressure brought to bear on legislators by art supply retailer lobby group. Evidently, banning it created a hardship as it is a major part of their business as well as selling other types of thinners so they appealed and got permission to sell it in quantities up to one liter I think. Evidently this only applies to art supply stores. So, that's where Californians can buy it. For now, anyway.
