Spray the wipers down with some silicone spray lubricant(take them off or protect the car) and let it dry, then enjoy.
Works great to keep snow, ice from building up on the wipers, wheels(avoid the brakes, though a couple of stops will take care of any that does hit them), wheel wells, mudflaps, suspension....
Also works well to keep your snowblower from clogging up.
You have to coat everything while it is dry(doesn't work as well wet but does), let it dry, you'll know when it does, a few minutes. Lasts for I'd say 2-4 weeks and than repeat.
It's also impossible to over do it.
Been doing it for going on 20 years with no issues, I even have a neighbor who is a HVAC service tech for a large company. Gave him the tip one winter, he used it, loved it, spread the word and it is now part of the their routine when vehicles go into the shop.
