Diesel RVs: Re: [diesel_mercedes] Re: Citric acid radiator cleaner

My guess is that the citric acid was reconstituted from its conjugate base of citrate (crystaline form of citric acid that has lost a hydrogen ion but regains it when mixed with water or a weak base); excess base would nudge the pH above neutral 7, but probably still provide chelation, or removal of metal deposits. As a side note, the interior of citrus fruit rinds is an effective edible chelation material for the human body (took and alternative medicine class last year).

    The MSDS is a little odd. It clearly lists that active ingredient as "Citric Acid". So it is strange that the stuff is advertised as "non acidic".

    The MSDS also says the pH of the stuff is 8.3-9.9, which makes it a base / alkoline, rather than acid. Cautions include the advice that ingesting large quanitites can cause alkolosis, which is a pH imbalance in the blood. Blood is normally in the 7.3-7.45 pH range (slightly basic).

    So, it would seem that the advertising is accurate - the stuff is non-acidic. That raises questions about what it is doing, how it works and what, if any, role the "citric acid" in it plays, and what other stuff is in there, doing what.

Sounds good to me ;

The MSDS link opens for a few seconds then gives me runtime error messages & closes again before I can read it ....
