>> 1) Take old rusty flange screws, put in jar with
>> muriatic acid ( available at hardware and paint stores
>> ) until rust is visibly removed. ( About 3 minutes. )
>> WEAR GOGGLES, MASK AND GLOVES !!!!!!!
>> 2) Rinse THOROUGHLY !!!!!!!
>> 3) Polish heads with Mibro (TM) "Mirror Finish" polish

>> 4) Put in another jar, with lacquer thinner, for about
>> a  day. ( To dissolve any Mibro residue. )
>> Strain, dry, put on rack and lacquer.

>> I got a truly "mirror finish" set of screws this way,
>> far, far easier than with any other method I've tried

>>     The main possible flaw in this procedure might be
