The coming of fall in the greater Cincinnati area is a beautiful time of year. From viewing the trees turn colors in Mariemont, voted tree city in the USA , to hayrides in Florence. Autumn is a fun and festive time, with cool morning and warm sunny afternoons. Howver those cool morning can leave a windshield, door glass, or back glass cover with frost or ice. Now you have to spend 10 mintues or more clearing ice from your car to be able to see for you morning commute. Now your late so you think about instead of doing a good job clearing the ice you will just scrap a small hole and let the defroster and windshield wipers do the rest. As you drive slowly down your street you are suprprized to hear sirens but you can not see where they are coming from becuase you can not see. WHAT? Your getting pulled over? For What? I was only driving 20 miles an hour! That’s reason your are getting pulled over because you can not see. It is illegal to drive a vehicle with your vision being impaired. That is right, snow ice, stickers, clothes, whaterver it is, if it is blocking your view and causes you to be a hazard on the roadway you can be sited.
So know that you know that you think, “OK, I will jusst throw so hot water on the glass and melt the ice and snow and be ready to go”” Stop right there. That could be a costly mistake.Say your car has a few minor dings or cracks in the windshield, typical damage from rocks and debris when driving on the highway. Well, those specks may seem minor, but they can cause major problems if you do not heed this advice.
It’s 20 degrees outside, and your windshield is completely iced over from the wintry mix the night before. You pour hot water onto that below-freezing-temperature glass and it seeps into those small dings/cracks and freezes upon impact. And we all know that water expands when it freezes. So now it’s in the crack of your windshield and it is growing with nowhere to go. This causes stress to the glass around it, resulting in a cracked windshield.
I have seen and tried this myself and it can work in some conditions. Your washer fluid has antifreeze in it, you can spray your windshield, and use your wipers to remove frost, not snow or even ice. If the weather is below 25, what happens is the additional washer fliud ends up freezing on the windshield, also freezes in you washer fluid dispensers and turns your wipers in to blocks of ice.
So scraping a small hole is not the answer, hot water is costly, washer fluid makes a bigger mess, so why not just go out early and warm your car up? Hold on again, believe it or not some states and local communites have laws against leaving a car unattended while running. I know it sounds crazy but if you leave a running car unattened you can be setting yoursulf up for a ticket and if your car gets stolen while running and unattened, it may not be covered under your car’s insurance.
So what is the best thing to do. A good old fashioned ice scraper works well and is fast if the ice or frost is not thick. There is also a windshield blanket that goes over the windshield and the ends get locked in the car so that it does not blow off, or get stolen. There are also the heated ice scraper, hair dryer, and hot air gun. I do not recommend anything with a lot of heat on a cold piece of glass. The thermal quick change as mentioned early will cause cracks to get larger.
If you can park a car in the garage is the best, warming up the cars defrost and using a ice scraper 2nd best, the frost blanket is good but a little of a problem storing, putting on and then it is wet when you store in you car. Worst things to do is to use heat from any source to melt the ice or snow that is how cracks can start and grow.
Should you have a crack appear in your windshield you should call American Auto Glass immediately, a small crack can be repaired in minutes and is a lot cheaper. If it a big crack or shattered back or door glass they will have it replaced faster than anyone in the business.
