Just recently, when I wash the windscreen with the washer-jets I get a really horrid smell. Smells like someone urinated in my washer bottle. I normally use a nice-smelling screen wash from my local car store. Is there any way to empty the screen-wash tank without just spraying it out? also, what could cause the smell ? I don't believe that screen-wash goes bad. Could there be stale water at the bottom of the tank that is now getting sucked up when I spray ?

The storage bottle is located behind the right front wheel.

Remove the fender well liner and it is right there.

I don't know if there is a drain but you can unmount it and dump it out or loosen a hose at the bottom of the bottle and let it drain out.

Thanx AMPM. Guess to loosen the hose will be the easy option. Maybe I'll flush it out at the same time.

Cheers Rattle !
I figured I'd flush it out while I dump the old fluid, but the tip of sterilising is a good one too. This is turning out to be a major operation, but I'll be glad when the horrid smell goes away.

You can get a handpump from a hardware store. You should be able to get the majority of the fluid out using it.

I think my battery leaked acid on the top of the washer bottle because it always leaks when I fill it up. When I changed my battery there was a decent amount of corrosion under it. Maybe it is contaminated by acid. I hope not but a thought.

My guess is that it didn't go bad, but rather a garage filled it up with winter formula. The stuff Mercedes uses from the factory smells like vinegar mixed with some kind of alcohol. Not quite a urine smell, but definitely not pleasant.
