Might help if the manufacturers suggested rinsing with fresh water

Never used one. I prefer to add a litre of antifreeze every year of
two depending on the work I've done on the car. But then I add it
mainly for corrosion protection.

Interesting feature on some 70's/80's Ford tractor engines.. coolant
cavitation causing erosion and penetration of cylinders! Not helped by
some of the coolant characteristics.

I had never heard of these problems but they are taken seriously from
the number of articles I found following a search.

The antifreeze in my car is "pH buffered".

You don't use hardware store antifreeze in it.

Check with someone first, before making a mistake
with your vehicle. I would never have suspected
such an option was possible.

And a lot of the stock here is pre-mix now, and
you no longer have to dilute it yourself. The
premix is 50% and I use it like that. Pour and enjoy.
