Good find! The sooner water leaks are sorted, the better.
My Mondeo leaked a little in heavy rain, and in winter, I used to find loads of condensation inside. Though it shifted with the heated windscreen, it wasn't particularly nice.
So I used these to solve the problem, and just got into the habit of using them.

The 5-pack has gone up in price from about £5 to nearly £8 now, so I bought a 10-pack last time I bought some.
These have all sorts of uses. When my kid dropped his phone in some water, I switched it off, bunged it in a ziplock bag with one of these, and a couple of days later gave it back to him.
But mostly I just leave on in the boot, and one in the passenger compartment of my car, especially now I'm not using it much as I'm working from home.
Edit: I've just changed the one in my boot (old one on left,), and as you can see, the white crystals have all gone, and there's a load of water now in the bottom of the container, so they do draw a fair bit of water out of the air over time.
