    Isopropyl alcohol

    I was walking around the neighborhood and noticed what looked like a 5 gallon paint can laying in the alley, but upon closer inspection it said 99% isopropyl alcohol and had a picture of beakers and flasks on it. What does someone do with 5 gallons of almost pure Isopropyl alcohol? I have never seen it used as paint thinner, other products remove adhesives and grease better, you can't drink it... is it used to clean electrical contacts? I know that curiousosity killed the cat but I can't help it does anyone have an idea?

    It may be for chemical lab use. I know that chemical labs use alcohol for their small burners.

    I had a job at a circuit board manufacturer a long time ago, and I remember it being used to wipe down circuit boards to clean off various residues. It evaporates quickly.

    Mainly used in computers, or electronics cleaning. I'm thinking the higher the percentage, the faster it evaporates as well. Also increasing the flammability factor.

    Now, we must all fear evil men. But there is another kind of evil which we must fear most, and that is the indifference of good men.

    We've got a few 5 gallon jugs of it at work in the chemical cabinet. We use it to clean various items (I work at a plant that manufactures NAND Flash). Not sure why one would be in an alley though...

    At NASA almost every piece of equipment that goes into a cleanroom is wiped down with IPA.

    Methanol and Ethanol are normal racing fuels. Denatured is also a solvent, maybe you got a meth lab nearby?

    Normally, IPA isn't used for burners or alcohol stoves. It doesn't burn clean and leave soot everywhere. Denatured alcohol is used for that stuff. IPA is used for cleaning lots of things especially now a days when chemicals are more regulated. I use acetone and IPA to clean parts that really need to be cleaned well, like paint prep. At my company it's the solvent of choice for cleaning oily surfaces.

    It's mainly used for cleaning off the flux left behind after soldering electronics as others have mentioned.

    Meth?

    I thought they used more caustic chemicals. Well if they are careless enough to actually run such an operation and leave evidence laying around for all to see the local LEOs should make short work of them. On the other hand we might have someone working on delicate electronics, I hope.




    Thanks for the input guys!

    Same thing with the cleanrooms at IBM. Even our laptops had to be wiped with IPA.
