What temperature is salt ineffective on roadways?

Mark Asked:
At what temperature does ice melt (salt) become ineffective?

We Found:
We spoke to Meteorologist Marshall McPeek, he says the city and the Ohio Department of Transportation states salt usually stops working well once the temperatures get below 26-27 degrees. There are other ice-melting products that homeowners can use that will work when the temperatures are a little bit colder.

Check the packaging when you buy salt, it will say how cold it will work.

No comments for you.

I heard years ago from authorities when I lived in Illinois that road salt loses its effectiveness below 16 degrees Fahrenheit. So it doesn’t sound like a truly effective deterrent to use if it doesn’t work below 26 degrees here.
