Hot dogs have sodium nitrides. They cause cancer.
All those rules were changed by the FDA back in '78.
But if you still believe that they are bad, don't eat them.
BTW, I clear my iced windshield with HOT water. And the glass doesn't break.
Now the no hot water on windshields USED to be a good idea... modern windows can stand a lot more stress.
You just have to keep up.
