(1) compressed air
In general, compressed air is enough to clear all the impurities inside the CCD chip. But it is not recommended to compress the air, because the compressed air in the spray often contains water, oil and other substances that may damage the surface of the CCD.
(2) micro fiber material
Micro fibers can penetrate the surface of CCD clear impurities, so as to achieve the purpose of cleaning
(3) pure alcohol (above 90%)
The material can be purchased in nearly all of the chemical reagents store. But pay attention, do not use the alcohol, because the alcohol will absorb the moisture in the air, leaving traces of liquid on the surface of CCD.
(4) alcohol substitute
In addition to alcohol, methanol or a liquid called Eclipse can also be used to clean the surface of the CCD. But we do not recommend the use of this method, because methanol is a highly toxic substance.
(5) above a variety of methods to use
Above all kinds of methods can be integrated, clean the surface of the camera CCD. If the finger touched the CCD front of the glass, do not have to worry, this layer of glass is very hard, unless the use of a glass knife, sand or diamonds, it will not leave scratches on its surface.
