Last and this year I noticed that the damage caused by the winter use of my older vehicles somehow changed. Salt -> rust, of course, but even the rust doesn’t look like it used to be. A light orange dominates steel sheet parts, which makes me think more of an acid treatment, and in the engine compartment I have both the die-cast parts of the beetle and the BMW E36 horrific blooms, which I don’t know from the past. The magnesium alloy of the beetle engine doesn’t seem to hit it that way, but distribution housing, gasoline pump etc. get a chilly skin that hurts while looking at it. At the BMW it seems to me that the differential is rusting through…. Does anyone know if something else than sodium chloride is being cut on the streets on a larger scale nowadays? Will probably depend on the municipalities, but such general trends should be known…. Greetings, Michael
