Degreaser is a common part of a car mechanics life. Especially so 30+ years ago where it was more common to clean and replace parts than now when it's more usual to just replace any removed part.
This is counter-intuitive but I guess there are cases where throwing away the part and replacing with a new one is MORE environmentally friendly that reusing the part—when it involves not-so-nice solvents. I hadn't considered this before.
Maybe. Depends on how environmentally friendly manufacturing, packaging and transporting the new part is. I suspect it’s a win in chemical terms most of the time, but it may not be an overall blowout win.
