To minimize condensation (fogging) on the inside of the glass:
1) Reduce the amount of moisture in the air, inside the cabin that comes from breathing (and sweating and water splashed inside to a lesser extent). Run the A/C to maximize it's dehumidification & have the outside air (aka ventilation) turned ON so the dryer air outside comes in and dilutes the moist air inside.
2) Reduce the visible blocking of the water that happens to condense on the cold glass by making the droplets smaller and more separated. The easiest way to do this is to clean the glass so there are fewer, smaller dirt particles on the glass for the moisture to grow from.
Cleaning the glass is one way. Use soap, toothpaste, shaver's gell/whatever. I'd Windex, (aka: a mix of ammonia, soap, and water) wiped down with a microfiber rag. Used to be, there were newspapers that worked great for this, but who gets a paper anymore?.
Rain-X on a clean glass will fill in the micro-cracks in the glass and block almost all drops from forming, so the "cleaned glass" stays clear, longer.
Car windows have been fogging up ever since the modern automobile was created you just crack the car windows aa little problem solved it’s not hard people.

If you don't clean the windows once in a while then that won't always work. At least it didn't on several cars I had until I started keeping them clean.
Yep, run the A/C with recirc off to dry out the air. I see people driving around with fogged up windows like they just had a steamy makeout session in there. These are newer cars so the A/C must work, they just don't know how to use it.
