Windshield washer fluid is stinky - what to do?
The windshield washer fluid in my car has turned stinky. Smells like rotting sewer water. I have tried adding:
fresh biodegradable solvent (hint of ammonia)
fresh cold weather solvent (methyl alcohol)
apple cider vinegar
Nothing works. Is there anything else I can put in that won’t destroy my windshield washer pump and/or hoses?
