Just a thought, I have been watching with some interest ALL the mollasses debate, including quite a mass-debate ( or something that sounded like that) the other day on the subject of "ooh- dare -I- use- this- in- my -tank...what -do- you- think,- please -will- someone -else- do -this -for -me -cos -i- am -too-scared- to- risk- my -own- tank-" sort of thing!
well I had an idea, why dont you just get a jar, any jar,throw some rusty nuts and bolts in the said jar, add the mollasses (that you are frightened to put in your tank!) and see if it removes the rust from the rusty nuts and bolts, THEN decide on whether or not you wanna put "old granma" in your tank !(in her "mollasses" form or otherwise)
ding goes the light-bulb sometimes in kaceyf2s head.
