    13 Unusual Uses for a Hair Dryer

    For years I've defrosted my windshield with 120-degree water with no problems, although maybe the laminate structure changes the game. The shattering (or cracking) of glass with rapid temperature change will be much more likely with the presence of any imperfections in the glass, or hairline scratches on the surface, etc. It should be noted, defrosting glass only requires that the glass be heated to 33 degrees F, so gentle/even heating from a moderate distance with a hair dryer should minimize risk and still be effective.
