Windscreen mould!

[Nicksey]

Anyone else seeing a mould develop along the bottom edge of the windscreen, just under the glass?

After 8 months of ownership from new, I had to have the windscreen replaced due to delamination (our dealer had replaced 2 others for the same reason)... and now I am seeing mould 16 months later!

Always clean using Autoglym products, and quality screen wash products.

My Crsstar too, 20800 miles. 3 years 4 months.

Will query with dealer.

I have had this on a few of my cars since leaving them not garaged on the drive, it's easily removed with a toothbrush or similar dipped in washing up liquid

I also have the same 16 months old will shift it in springtime
with a drop of vinegar.

Not when it is behind the glass, as is this case.

How do you get the vinegar behind the glass?

I've had algae growth on window rubber of other cars.   I think it may be algae rather than  mould.  Algae is more like green plant growth  while mould is a fungus that can be more  pernicious, creeping and causing damage  .But both equally unwelcome, and potentially difficult to access for treatment.     I think treatment  methods would be the same for both but it might be worth checking further re the best   treatment/prevention products. 

I may be stating what is already obvious to you  but looking very closely at the bottom edge of my windscreen there is a very  narrow strip of rubber  which abuts precisely against the glass edge/thickness . And exactly level with it.  It does not overlap onto the outer surface of the glass  but may  extend up the inside surface a short distance. The area thats affected.    In other words the glass rests on L  section  rubber rather than enclosed in U section. Probably intended to act as  weather  seal until it reaches the  mastic/glue used to bond the  screen to the car.
 
It seems water may  have  penetrated behind the L section of rubber allowing algae growth in what is  now effectively a greenhouse.

It might just be possible to insert a very thin L shaped piece of metal bewteen the rubber seal and the affected inside of the glass in a way that the algae growth can be  scraped off. Then   it may be possible to introduce some sort of  killer/prevention  fluid  ,being absorbed by the same capillary action that  allowed water to penetrate in the first place. Or maybe try   fluid without the scraping stage     If it successfully kills the growth it may turn brown and not be so obvious.     But it might not be possible, or  cause damage or make things worse.    Rather you than me   and at your own risk

Windscreen replace and now mould on the inside sounds like the surround wasn't prepared properly

Who fitted the screen ?

Sorry, I got the impression from your post that the mould was outside the glass, it may be caused by condensation forming on the glass in winter  and /or not using the aircon often enough, if you can access it same applies, toothbrush soapy water

Honda. It was replaced under warranty by my dealer.

I have used the air con throughout the winter, and have had very minimal condensation. There is no chance of accessing the area with a toothpick let alone a toothbrush, it is under the glass and there is no gap.

Oh OK, just trying to help

I'd be going back to the dealer that fitted it and ask them what they are going to do to fix it

I am lucky then mines only on the outside, if I wipe my finger across
bottom of screen my finger will be green, strange thing is though if you imagine
standing at front of car its only occurring from centre of screen to three quarters
of way across screen to passenger side not to the end of screen and doesn't start
till centre of screen, I had insignia before jazz and that was the same but right along screen
and along all four doors at bottom of glass came off easy with some product made by autoglyn,
there are no trees or bushes where car is parked on my driveway.
