Hi, 

 

Recently I have noticed a grease kind of buildup on the inside windows of the car, mainly on the front and back windows. I have no idea where this is coming from and when In direct sunlight makes it nearly impossible to see out of. I have been cleaning it with Mr Muscle window cleaner but this appears to be just a shot term fix. I have been Into the Skoda garage and was told that this can happen from the air conditioning as it moves air around the car. I didn't think this was a valid answer and one of my colleagues who owns a Golf says he has the same issue sometimes, however it is nowhere near as bad as the Skoda. 

 

Anyone got any ideas on what could be the cause and resolution of the greasy windows? 

 

Its due a oil change in the next few thousand miles so I might ask them to check the air con filters etc to see if that's the problem. 

 

 

The film on interior windows comes from plastic in the car being effected by the heat of the sun. According to google the best way to remove the film is use vinegar.

Another thought - you're not a vaper are you?

Check that your engine coolant expansion tank isn't showing any loss of coolant.

You'll be amazed how much dirt build up you get in then rubber seal around the windows

 

They also clean well with vinegar and a cotton rag 

 

The single most frustrating thing I find about cleaning windows is the lint residue left by microfibers left over from washing your drying and buffing towels.

 

Try using a clay bar and really give the glass a good once over , clean the glass and clean the seals...

 

I'm still amazed at how effective good old Vinegar/Water in a spray bottle , gloves and a newspaper can actually be....
