Peter,

If you do decide to dismantle it, which probably is the best way to be sure
that you get ALL the rust and all the other crud out as well, be sure to
NUMBER the JAWS and their positions in the chuck BEFORE dismantling it. I
believe the other posters may have overlooked this in their zeal to abolish
the rust. Abolishing rust is pretty close to the Holy Grail for most of us.

I hope one of you nice people here can tell me how I can clean my 4" chuck.
I just got it from a neighbor that was going to toss it. It works swell,
but has some surface rust. Please take in consideration, that I'm old, weak
and run out of air quick. I still like to get it done. One day the
grandkids will have it, and I like to leave it in at least clean
condition....What if I dunk it in acid, of course diluted. I'm sure you
will talk me out of it, it is dangerous, and I think it does something with
the hardening or makes it brittle maybe. I'm not sure what it does. I
purchased a nice V block from EBay once, and it was real nice and shiny. It
doesn't look that way now. It only been in my house, and I live in CA, no
moister anywhere. So I think these guys have some sort of secret formula. I
don't need the formula, but maybe a comment or two. As you can see I'm
really in need of help.....Peter
