windscreen wash smells of urine

Honda Accord 199 Auto
bought second hand, reservoir for windscreen wash was empty when bought.
Dont know how long it was in that state. There was a "floater" sponge like
thing
inside the reservoir which looks intact.

I refilled it with fresh, cheap screen wash which smelt ok in the bottle.

However everytime I use the screenwash while driving, its as if some
buffalo has done its business on my car - the smell is so uncool.

Any ideas on how to get rid of this smell?

 

You may want to fill the resevior with water and run the washer until the water
empties, refill with water and continue to wash out the smell. It is a lot
cheaper then using windshield washer fluid. A drop or two of dishwashing
liquid in the water wouldn't hurt. If this doesn't work, then you didn't
really waste any money to rinse our your system.

 

Dish detergents are a good source of food for microorganisms so that
alone might make the stink worse. Adding a shot of rubbing alcohol, but
not too much because it could hurt the paint, should help.

For the purging, hydrogen peroxide should work great.

 

dump a whole bottle in. thats what the windshield washer antifreeze is.

 

Or look for a "winter" formulation.

 

same diff. id take the bottle out and rinse with bleach and hot water.
should get rid of the buffalo piss stank.

 

Also, clean the vent grill in the engine compartment just under the
windshield. It is a grunge collector, which starts to mold. When
you use the washers, some drips through the grunge into the vents,
smelling bad...
