    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.

    The EPA has become just another arm of the government that can enforce policy without congressional oversight and without judicial review. What other branch of government has such broad authority to confiscate housing, shut down business, and administer fines without due process of law?

    The Federal government really has no authority to create such an agency. Environmental regulations should be done at a state level, and, for example, should California decide that a Pennsylvania oil refinery is causing a problem in California, the matter should be taken up in federal courts.

    Having said that, if L.A. county wants to ban Naptha, that is their business. If they think a few people with Zippo lighters are going to poison the city let them waste their money on such legislation and enforcement.

    Without the EPA we would all be dead from industrial pollutants.

    Having lived in Southern California since the early 1950's I can assure you there has been a tremendous impact from Environmental Regulations.

    There were many days back then when kids couldn't even go outside to play and you couldn't even see whole mountains just 5 miles in front of you.

    Thank God, Americans had the courage and foresight to create an Environmental Protection Agency.

    If you want to live in polluted filth and squalor, there are plenty of countries waiting to accept you.

    Was that not mostly from automobile exhaust and not industrial pollution?

    Lots of industrial pollution as well. Refineries, furniture factories, auto assembly plants. Backyard burning too. As kids everyone had an incinerator in their backyards for burning leaves, trash and papers.

    I don't think anyone under 35 has a clue of what it was like.

    Heck, Lake Erie caught fire.
