Try to wash your car once a week in winter to get the salt off. Might make it last longer. It will still rust out in the end though.
The advice about about antifreeze and windshield washer is on point though. I would also say that once I got winter tires, it’s been very hard to go back to all seasons in winter. Good winter tires like Bridgestone blizzack just have so much grip.
Tip of the Zoidberg? The yeti one.
Thanks for doing this. I want to see more.
