No one, including me. But to this point, no one had specifically said
otherwise either, and there was bound to be someone somewhere who would
decide to clean his whole system with it. Plus there is the real
possibility that someone could fail to completely clean all the product
out of the rad/heater core before reinstalling it, especially if someone
on a list has told them it is "safe" to use with aluminum. Bottom line
is this is not something to suggest to the average DIYer, in fact it is
just plain a bad idea period. It's like using gasoline to clean parts.
Sure it may work okay for someone a few times, but it is inevitable that
someone is going to end up regretting the choice.
