    removing rubber from valve stems

    Trying to figure out the best way to get the rubber off valve stems, was thinking about burning them cause they are tough to clean. Does burning hurt the value of the brass? Or does leaving the rubber coating on even effect the value? I have a ton of these things and wanna get the most out of them.

    If I didn't have bad luck, I'd have no luck at all...

    Clamp down vice grips with it in a vice and twist them around, have you checked to see if the needle inside is magnetic or brass? If so and you leave it in then taking the rubber off is going to be a waste of time.

    We take all the valve cores out, most of the valve stems are old ones out of rims we put new tires on, so the needle things gotta come out to release the air. But that's a great idea with the vise grips, never thought of it. Thanks!

    First, don't burn stuff, especially rubber. your yard might buy it as dirty brass. You're not going to be able to justify cleaning it, unless you can clean 10 lbs or more an hour. If you can clean 10 lbs an hour your only gaining the diffrence between clean and dirty. You also loose the dirt weight so you have to adjust your price per pound gain /- the dirt weight .

    These numbers are arbitrary- say 10 lbs of dirty brass $1.30 per pound= $13.00
    Cleaning that 10 pounds nets 9 pounds of clean brass at $1.60 per pound=$14.40
    Of course these numbers are made up but in this example you only realize a gain of $1.40 if it only takes a few minutes or you have no.other source of scrap then $1.40 is better than 0. However, I'm confident you could go out and find $1.40 in scrap or find better things to breakdown.

    Depending on where the rubber is, I take my utility knife and stick it along the side, and gently pry it out. Don't burn anything plastic. It will release dangerous fumes into the air that you don't want to breath in.

    Wow, when I first read the title I thought this was a joke. Not to insult anybody, but wouldn't your time be better spent doing ANYTHING else?

    WOW!!! I learn something new everyday on here! Thanks, had no idea those could be brass! Now when I'm all caught up I can go check out what I have outback.

    *****obviously I may never get to them, but you never know one day I might be down on my luck and have no other scrap around to make money off.

    Lol when you're off work at trade school and no access to your truck till you're done, what else are you gonna do when you get home? I don't get paid to go to school, so I need as much income as possible. And its only a minute per piece, if that's 10lbs an hour at over 2.00 per lb , that's $8 more than I make at work per hour. Seems ok to me, that's gas to get to school for a day!
