What solvents do we like?

  1. I use Chloro-Kleen which I purchased years ago when it was legal.
    Unfortunately it's running out now and I was wondering what all you guys
    like...

    I use isopropyl for some stuff, and MEK for cleaning flux from boards, but
    nothing beat Chloro-Kleen for rubber parts...

    I Use Fedron for all rubber parts which works great
    Isopropyl for most everything else

    I couldn't find a breakdown of fedrom on the web but the can says in
    contains:
    Xytol, Ethyl Acetate, Methanol, Ethanol, Hexone, Aliplactic Naptha, Water
    and compound oil

    Graham:

    Cloro-Clean was Tri-Clor when packaged by General Cement. I have no
    idea on Fedron.

    I now use isopropyl alcohol, but I used to use Freon TF.

  9. Chloro-Kleen contained 1,1,1 Trichlorethylene and petroleum distillates,
    according to the label. Don't know what exactly.

    Curious what you are cleaning flux from .
    I never had any issues with the little flux that stays around the solder
    joint .
     
  11. And 409. Can really work wonders on the grime left on exterior surfaces
    (viz control panels and keyboards.) DO NOT SPRAY DIRECTLY ON the device.
    Rather, spray a cleaning rag heavily and work with that. Sometimes
    laying the cloth over 'stubborn' areas and letting it soak works a treat.

    I second Goof Off -- but be careful with some plastics.

    I use this stuff for removing flux. It's not the fastest dissolver but
    I've never seen it damage anything.

    Flame time. I also use Xylene. This _NASTY_ stuff was the official
    head cleaner for Ampex 1" type C video recorder and it is drastically
    superior to any alcohols. Any tape residue on guides, heads and
    capstans will come off in seconds but it destroys styrenes. For laughs
    I tried it on some rubber pinch rollers in Sony Betcam SP decks. If
    the rollers have less than 1000 hrs run time, they will look virtually
    new with a Xylene scrub. You can get Xylene at Home Depot for $12/
    gallon.

    Polystyrene, principally.

    My fav'rit's methyl-ethyl ketone. Like, wow, man...
     

  14. Thetas because you don't work on industrial, military, or aerospace
    grade electronics. Flux can, and does adsorb moisture, which can cause
    leakage paths on a PC board. If its humid enough, it can damage bare
    copper traces, over time. On cheap throw away chinese shit doesn't
    matter if you clean it, or not.

  15. Sometimes flux can get really ugly looking. I like for a board to look
    really good when I'm done with it. Best of all if it's really hard to tell
    if someone has even worked on it at all !

  16. I'd forgotten about Xylene - maybe the brain cells died from smelling it in
    magic markers.

    I figured it had something to do with high grade equipment . About all i
    work on is cheal chinese ``shit`` I have cleand up flux before when it
    about takes over .

    Also agree about 409 its good stuff . The tire cleaner is a step further
    It will ruin anodized aluminum . Once you get used to it it really
    removes all sorts of dirt in a big hurry .

    Soap and water, or just plain water.
    Isopropyl alcohol
    Diesel fuel to loosen grease.
    Weak Acetone (AKA nail polish remover)

    Nothing really like Tri-Clor or MEK.

    For cleaning accumulated crap off pcb's I use Domestos (a hospital
    grade cleaner you can't get in the US). Washed down afterwards with
    plain water and thoroughly dried off with a hot air gun.

    For electronics components or small areas on otherwise good condition
    pcb's, I use Isopropynol.

    For removing glue residue or labels with non water soluble adhesive I
    find kerosene does the trick. It will usually cause the label adhesive
    to soften to a gel where it can be removed with a paper towel or
    tissue and then finally clean up with a paper towel wetted with clean
    kerosene.

    In no particular order:

    Ammonia
    Dilute Lye or spray lye-based oven cleaner (best grease, skunge &
    paint remover bar-none for those surfaces that can accept it and may
    be cleaned with water afterwards).
    91%+ Isopropyl Alcohol
    Acetone
    Petroleum Naptha (standard paint-thinner)
    Methylene Chloride - outdoors in a breeze only
    MEK where lye cannot be used - as above.
    Olive Oil (try it on gummed areas, just once if you are surprised.
    Almost any cooking oil will do something, but Olive Oil has a high
    percentage of Oleic Acid in it).
    Methyl salicylate (synthetic oil-of-wintergreen) for non-residue
    penetrating-oil applications if you can stand the smell.
    Penetrating oil.
    WD-40 (actually light-fraction kerosene).
    Stove Alcohol (methyl alcohol) - not good on many plastics so be
    careful.

    About covers it.
    Due cautions for HTA explosive potentials are to be noted.
