I'm trying to figure out a good way to clean coolant off from the inside of my windows. My heater core failed and coated my windows. Whats the best way to clean them?

I've tried 50-50 90% Isopropyl alcohol and water. That seems to just smear it around. I have read some where that use hot water and Dawn dish soap, then the alcohol to clean the soap film off.

Anyone experience this and if so what was your clean up trick? That wont mess up the dash etc.

Thanks.

 

Come on. I find it hard to believe that no one ever had this problem. Using the heater on full blast and vaporized coolant coated windows?
