“Back in the working day, when we used salt and sand, you experienced rust and you experienced corrosion, but it seems like in the previous 10+ decades, with this calcium chloride, every thing is rotting out on vehicles…Rotted brake traces, rotted gas lines…fuel pumps…some frames rotting out. Anything that has a metallic composite to it, this chemical just will get on, and just eats and rots it, and corrodes away.”

This incorporates pieces like the:

  • Exhaust process
  • Muffler
  • Coil springs
  • Subframe
  • Hydraulic brake method

Now, back to Jenak for a breakdown on what this has to do with rust:

“It’s a mixture of normal rusting of every single car or truck mainly because each individual auto rusts. But this calcium chloride just fundamentally puts the corrosion amount and corrosion element into overdrive. It is a humidity activated chemical, so even when the winter is above, you get a nice, wet day in the summertime or a moist dewy working day, it activates the chemical.
