Cola cleaning


G’day; There have been one or two suggestions to use coca-cola
for metal cleaning and as a firestain remover. The active
’cleaning ingredient’ in cola(s) is dilute phosphoric acid.
This is sold as ‘rust remover,’ and is reasonably dilute, but not
anywhere as dilute as in the colas. It works very well for
getting rid of the last traces of rust after sanding etc., and
makes a good preparatory surface for subsequent painting. Pure
phosphoric acid is rarely seen other than in laboratories, when
it is syrupy. I doubt whether the other ingredients in cola
(sugar, etc) would do much toward cleaning metals. It (sugar) is
good for helping teeth rot though. Cheers –
