This is why bought in bits are easier. How much time have you spent trying to adapt technology? Your time has a value.
Is this the end of the problems? possibly not, have you considered low winter light, rain, lens condensation, electrical interference etc etc.
Don't get me wrong Im not knocking you for trying, in fact its the opposite but if your really busy and realise getter cleaning is a valuable add on service then bought in equipment is the only way to go.
