Cleaning Block Waterways

[Dennis Nicholas]

I have used the Deox-c. It works well removing all corrosion.  The solution can be used again and again untill it no longer works - check with a small rusty off cut.  I think that using a strong solution rather than a weaker one would be best.  It took several days to get my bits cleaned up enough and as suggested fairly frequent agitating helps as well as scrubbing the surface with a wire or other brush to remove the black deposite from the chemical action to reveal shiny clean surface.  You can make up enough solution in a large enough plastic bowl to put the whole block in fully immersed which would do the outside as well. Once satisfactorily cleaned the piece can be just washed off with clean water. The bottle of powder goes a long way, making up lots of solution.
Several members of my Reliant Scimitar club have also cleaned out their V6 3litre engines and radiators using neat Coca-Cola, but of course it is not re-usable afterwards  .
During use the solution gets progressively blacker.  With more gentle use on something not too badly corroded the remaining solution can be drained through a filter (coffee filter) into a container for storage till next needed.
