    *Disposal within San Francisco*

        Curbside pickup of oil, oil filters, anti-freeze, batteries and
    latex paint is available in most areas of San Francisco. Call
    800/449-7587 for information about how to schedule an appointment.

        If you are a San Francisco resident, you can properly dispose of
    your household hazardous waste at the Household Hazardous Waste
    Collection Facility at 501 Tunnel Avenue near Candlestick point. The
    hours of operation are Thursday, Friday, and Saturday only, from
    8:00 a.m. to 4:00 p.m., except on certain holidays. Call the
    Hazardous Waste Hotline at 415/554-4333 for specific questions about
    using the facility.

        The facility accepts painting supplies, antifreeze,
    photo-chemicals, aerosols, fertilizers, cleaners, car batteries,
    motor oil, medical waste, asbestos, solvents, poisons and resins.

        The facility _DOES NOT ACCEPT_ radioactive materials,
    explosives, materials that are reactive with water (e.g., calcium
    carbide) or pressurized gas cylinders over 20 lbs.

Sounds like they'd accept ferric-chloride and other used etchants.
