[Hallicrafters] Wrinkle Paint

Wed Apr 20 20:59:12 EDT 2011

Sulphated molasses and water in a 1:4 or 5 ratio is a centuries old farmers 
deruster that also doesnt attack good steel or iron. It takes a week or more 
but the part must be degreased and paint removed so its not too good on a 
radio cabinet. It is better than electrolysis when there are deep hidden 
areas such as engine water passages clogged with 70+ years of deposits..

Its not dangerous or toxic and the residue is good for your garden if they 
like iron.
