Really, I can not remove it by stirring or? But one thing why when use this vanish for longtime the cloudy seem like slightly disappear? Is it possible that the moisture is go away?
in case that I have the humidity in vanish how to evaporate or remove it out? The humidity in the air we can control with the air hanlding unit with can control both of temperature and humidity.
My lenses is definitely CR39, but the heat and humidity should be the cause. what is the properly condition of the vanish? This couldy will always appear even this hard coat is fresh or obsolence.
I had dip CR39 lenses in the vanish when I lift it up I found that the surface is become milky like cloudy. Who have the same experience like this, please support.
