I have a electro-static air cleaner. This electrical system init is inside the air-condition/heater air duct. This system has a removable electro-static charged plates in the air flow.
In time, these plates are coated with dirt. I can wipe it off using a Q-tip. But these fins are too narrow gaps to wash. I tried Windex and did not do much. Is there a good way to wash off these dust & dirt?
