Molasses and Rust Removal
With all of the chatter on the List lately about galvanizing, zinc treatments and other rust prevention and removal techniques, maybe it'san appropriate time to share the results of a little test I did with molasses. Some of you may recall my and others' previous postings about the rust removal properties of molasses.
Like most of you, I happen to have "bits bin" of old random ironmongery: nuts, bolts, washers, screws, springs, old steel vehicle bits, Jimmy Hoffa's cufflinksand the like. Unlike most of you, I didn't have the sense to store my bin of ferrous fiddlery far enough away from the basement sink, so my collection got the benefit of several-many weeks worth of standingwater to form a nice thick crumbly oxide...real boilerroom of the Titanic action. (Umm...if you'denjoy appropriate background musicat this point in the tale, just click here).
So anyway, after shakingthebrown mess around a bitin a sieve under a running tap to loosen up and rinse away the loose scale and rust dust, the picture below below shows a random sample of what remained after drying:
Next, I threw the whole mess back into the little coverless plastic trash can that serves as my bits bin, mixed up a solution of about half a pint of molassesand a half gallon or so of tap water (just about enough to cover it all) and then just let it sit for a few weeks, giving the can a little shake and a swish now and then when I went down to bring the drugged gruel to the hitchhikers I keep chained behind the water heater.The picture below shows what emerged about a month later:
So, clearly that old mechanics' wives tale about molasses dissolving rust is true. For my next trick, when I finally get around to rebuilding my trusty old shed-bound Norton motorcycle (that once upon a time took me to my very first Swim-In), as well as reprising the molasses technique, I might also try cleaning its many aluminum alloy engine partsby boiling them in a huge pot with rhubarb, which is something I'dfirst heard of in Scotland. Just think how overjoyed Mrs. Bilgey will be!...even more so, when I mix the two concoctions and makePIE! ("Never fear dear, the heavier bits willsettle on the bottom, so I'll just scoop off the top part like this, see?")
Bon Appetit!
