Dew usually appears around the windshield due to differences in air temperature, including dew that appears in the rearview mirror.
Mechanic who has workshop in Jakarta, expose a way to resolve the issue. That is by smearing the liquid hair shampoo (without mixed with water), to the entire surface of the rear view mirror in moderation, because if most could even interfere with vision.
Rub the shampoo in the rearview mirror is not too much. Simply by lightly greasing and foremost still looks clear and does not make so unobstructed view.
 liquid shampoos contain chemicals can block the deposition of water vapor, as liquid shampoos contain chemicals with certain PH, thus preventing condensation on the glass.
Although the function can remove hard water deposits, but is not recommended for use on the glass front or side. Good luck.
