The case of some small details often have a significant impact! Fog appears on the automotive glass distracting believe that the majority of drivers have experienced, too common problem. But usually not when fog generally do not pay attention to details to solve this question, and got the situation encountered fog but can not find out what has changed in the way of driving, only with a dry cloth or tissue paper when taking advantage of stopping at traffic lights Cabo hard, parked the car actually does not affect anything, the arm is a little fee, but if in motion, in particular, can not stop the high-speed road, this is very dangerous! so this is not to ignore the details.

The reason is that the windows fog "outside the heat of cold" big temperature difference may be more than ten degrees in the winter and even up to 20 degrees, so there will be fog on the glass, this physical sense then this will not repeat them. Following editing to share some of the ways on how anti-fogging and defogging with you.

The first method - with special products demisting

In many markets Auto City and other places, there will be some special anti-fog products sell demisting booth, such as defogging agent fog or towels. Such a defogging agent is sprayed onto the inner surface of automotive glass, and wipe clean, clear glass at the same time the dirt, a thin transparent protective film may be formed on the glass, it is possible to prevent condensation to form on the glass fog layer, one may rub antifogging spray ten days - about half. Of course, the easy method of drawing money for such a simple problem of fog, presumably to spend this money is not the most cost-effective.

Comments: Buy defogging agent anti-fog a little less effective, and it is no longer valid role, editing is not recommended to use this method.

The second class methods - Convection fenestration

If the fog is not the case, we can open the windows on both sides of a gap (being unable to do so when it rains), so the car's air convection, the temperature inside the car slowly near the outside temperature, the fog will dispersed. Advantage that we can achieve the effect of open air without increasing fuel consumption, but this method is not all cases can be used, such as winter and when it rains can not.

Edit Summary: in case it does not rain and the temperature can accept this is a good method, the disadvantage is not appropriate to use when a high-speed run.

The third method - air-conditioning system

We met in the winter and rain in the windshield fogging, I believe many of my friends have used air conditioning system to defog, in fact, there is some skill. I believe many of my friends are using cold or warm air defogging effect is good there is doubt and controversy, in fact, the problem is two-fold, due to different situations and proposed.

The usual practice is to open the car and the cooling fan switch, so that the cool air will be blown into a mist scattered and quickly make the glass, very direct effect soon. This is because the cool air is blown onto the glass, a "cold film" formed on the surface of the glass, to prevent carbon dioxide condensed on the glass, play a defogging effect. This method has a biggest drawback is that the car might feel cold, Imagine prone to fog and rain in winter, in the car airconditioning taste really feel good! Blow a few minutes might wean and soon began to mist hanging in the glass, and open air ...... not convenient so repeatedly and operating temperature inside the car would be very inappropriate, another bow to the operation of the security risks caused some too. Of course, if you are physically very strong and has just been completely or intense exercise, this method can also be used to scrape together a living.

So with the hot air can demisting? The answer is completely! Open the hot air, neither additional energy consumption, can comfortably drive, do both!

But there is little to remind you, open the hot air in the case of glass have been traveling in fog, but fog on the glass will become more and more serious, in the rain when the air much water is even more evident, we will look at the front windshield become frosted glass, very dangerous! so editing would be best not to try blowing hot air to the windshield while driving. Preferably before traveling on to the glass with hot air drying.

In fact, with a glass of hot wind and the effect is better than the cold wind, but the process is a lot slower than air-conditioning. Just open when the fog does make the inside of the glass becomes greater, because the greater the temperature difference between inside and outside, such as hot air drying after the moisture inside the vehicle, the glass becomes translucent, like a few minutes to process. During operation the car is parked on the roadside, open the hot air, the temperature was adjusted to 25 degrees or more, waiting for the fog to the inside of the glass all dry temperatures will reduce the number of OK, so the process of moving and will not play again fog, because the car dried. Tips: to ensure that no hot air like fog, do not get too hot, get off colds.

Tips:

In addition to the front windshield, side windows will fog, mist on the front side windows will affect the driver to observe the rearview mirror. The car now has a single blow of the front side window vents, but generally very small, if that effect is not obvious, we can close the two center air vent, so you can make the outlet side of the greater air volume. (Some high-end car air-conditioning is individually controlled, may not apply)

Edit Summary: Air defogging effect quickly, but the car would be more cold; hot slower effects, such as hot air demisting along the way were very fresh and warm before traveling.

Method fourth category - detergents antifogging

If you still feel hard to remember the above method, complicated operation, may wish to blending our own "anti-fogging agent" to prevent fog. Online tips and programs are also introduced many, the easiest is to use detergent behind blending. Water and detergent behind the ratio is about 1:10, and then with a clean soft cloth or absorbent cotton dipped apply it to the inside of the windshield to front.

Until dry and then wiped off with a suede like residue left in the inner glass watermark. This is a good approach, principles and spray fogging agent dedicated basically the same (the effect may be somewhat less), but do not spend money without operating the air conditioner can keep for some time, is a simple and economical method.

After the windscreen demisting - can be heated

Currently on the market are basically the car "rear window heating" function position, the switch button sections of the model are not the same, just look at the manual to find it just fine. Open the "rear window heating" switch, less than a minute mist will lift the rear window. Note here that the rear sight is also very important!
