Windshield Wiper Fluid... Mildew Smell

When I hit the wiper fluid, I receive an nice shot of mildew stench in my cab. What is this from? Thanks.

 

Have you changed the fluid lately?

 

No... Why would I smell it in the cab either way?

 

Maybe water has accumulated in the reservoir and mildew is in it. Thats the only thing I could think of.

 

I had some windshield washer additive from Volkswagen that I came across and threw in the WW tank last summer. It had a smell and you could smell it in the cabin when you used the wipers

 

pump all the old fluid through and get new stuff. I don't think you are supposed do this but I just use windex

 

Ventilation air intake is below the windshield. Any odor on the glass is going to be in the cab.

Stop using plain water and use 100% wiper fluid... stuff doesn't generally grow in alcohol

 

Sounds like an expensive way to wash your windshield
