    Amputate now before it spreads.

    Electrical tape is easier to remove without breaking the wound open.

    Evan: Would not duct tape be better for that application? Gary P. Hansen

    You know, the truth is I've never been able to tell any difference in my healing experiences with these minor cuts and scrapes, with respect to my first aid efforts.
    Seems like they either get infected, or they don't, regardless of whether I clean/bandage/apply antibiotics or not.

    Of course now that I'm wearing an older man's clothes I do always try to clean and take proper care, but sometimes that's just not possible right away.

    I cut my hand, badly, about ten weeks ago, trying to remove a rusty canning ring/lid from a jar of old tomatoes. I mean down to the bone for about an inch and a half. That hurt like hell! I thought my hand was on fire, with that tomato juice getting in there. I only had paper towels and duct tape to cover with til I could get to an emergency room. After about a 3 hour wait and 4 stitches I was on my way. It's healed nicely, hardly a scar, but still feels tender to pressure.

    BTW, I had a pair of work gloves setting about 3 feet away when that happened. And furthermore, the thought had run through my mind earlier when I'd started (had several dozen jars to do), "Hey stupid, you ought to put on those gloves!"

    Had your blood sugar level checked recently? Diabetics take longer to heal.

    I know.

    I think he'd be closer to the cause by blaming it on the phase of the
    moon or even "global warming" than an alloying element in the
    cutter. :-)

    Isoproponal is also great for wounds.

    I think its isoproponal for new wounds, Hydrogen peroxide for old ones.

    And yea, iv used the electrical tape bandaid, but I put a little paper towl beween the tape and the wound.

    And yea, Wounds that get the weird cutting fluids in do seem to take a lot longer to heal. a solvent like isoproponal to dissolve and flush it is likey a good idea.

    I don't think they take into account wound recovery time when designing cutting fluids. There would be a nifty idea. Neosportap. The cutting fluid that helps heal/disinfect wounds when you accidently cut yourself!

    It's probably because of the cutting fluid. When I had a mishap with a trepanning cutter on the mill, I managed to rip my hand out of the way before the tool came around twice. The cutter wiped across three fingers, making things very colorful. My hand was red, the air was blue. The gashes took several months to heal, and though they did finally heal there are distortions that will never go away.

    I used to use hydrogen peroxide on most wounds. However, I've heard increasing comments that it can actually slightly slow down the healing process. For example:

    I still use hydrogen peroxide sometimes -- and haven't really had a problem with cuts healing. But soap and water and a bit of anti-bacterial cream might be even better.

    Epson salt solution is a very good suggestion as is hydrogen peroxide. BTW, HP is one of the few disinfectants that will attack staph & MRSA. If you do not have epson salts, table salt will also help as it is a natural disinfectant.

    By reaching under it to get to the workpiece to wipe it with a rag I cut my Finger, I should say I put a small scratch in it. Just about as wide and deep as a hair.
    Now the cut won't heal. It looks like a small Infection. In the past a small cut like this would heal in about 3-4 days. Is there something with the Cobalt or what do You think. No, No the machine was not running.

    Cobalt is only an alloying element in the tool steel, perhaps up to 10%. It is highly unlikely that an alloy component would have any effect on the cut itself. Chromium is a much commoner alloy constituent and it is used in higher percentages without ill effect. Think stainless steel 18-8; 18 is the percentage of nickel and 8 is the percentage of chromium. Nickel is a well known hapten, but stainless steel apparently causes no reaction.
    I suspect that some other factor is ruling the healing.
    BUT WAIT!!! There will be two or three witch doctors jump in here.

    Did you,

    1. clean with alcohol or other disinfectant,

    2. bandage it with some of the ointment (first aid cream) for small wounds?

    I find that if I do the above immediately and repeat as needed for a day or two to keep it clean, my cuts and scratches heal fairly quickly. If I don't, they can fester for days, get red with infection, and generally take longer to heal while bugging me the whole time.

    Do it now.
