[Boatanchors] Porcelain spreaders

[david knepper]

I am going to build an open wire feeder systems using 6 inche procelain 
spreaders that were made by E.F. Johnson.  However, the ones that I have are 
"coated" or embedded with soot particles after being part of an older feeder 
system.  I suspect that the feedline was near a chimney.    They are not 
bright and white like some others that I have.  I dunked the spreaders in a 
solution of Clorox and Tide overnight and with some scrubbing with a 
toothbrush, the results were less than satisfactory.

Should I have used my wife's dishwasher? or ???

I am sure that their insulating characteristics are fine but still would 
like to try another cleaning approach before I build the feeder system.

Thanks
