[SEL] Cleaning water hoppers?

[Chuck Balyeat]

Greetings from Japan.
Perhaps this thread has been discussed before I started reading SEL.If so, 
please run some of the good stuff by me.When in the States, I have seen a 
number of engines with immaculate water hopper interiors.How is decades of 
rust, grime, etc. removed?The finish I like best is the one similar the the 
blued barrelof a shotgun. Thanks, Standing by to hear from you.  Bill

Normally I insist on only purchasing engines with the proper service records 
from owners that insisted on using distilled water in their cooling jackets 
.  Otherwise , it's electrolysis time . I 've had to rod a few out with the 
a chunk of rebar( ribbed for her pleasure) Just so I can even start to cook 
it clean .  Follow the links
