Roger, Tks. Some of us "vintage" people still cling to small portal to our fast decaying Memory Bank! Re molasses, it is marginally acidic, generally 5-7 on PH scale. White vinegar is a more aggressive acid with a PH of 2-4. (A PH of 7 is neutral, a la water). #'s > than 7, are on Base side of ledger. BTW, "Whink" (brown bottle) in cleanser section of many grocery stores is a very dilute Hydrofluoric acid, (you can have skin contact w/o burn) and it is a very effective rust stain remover for fabric & small parts. Also many rust removing products at hardware stores have HF as active the ingredient. -BillTC 4926 [b]From:[/b] mg-tabc@yahoogroups.com mg-tabc@yahoogroups.com> [b]On Behalf Of [/b]Roger Bateman rogerbateman@rocketmail.com [mg-tabc]
