I went to the new Rural King store last weekend with my wife and her mother. They had windshield washer fluid for 99 cents a gallon. That is a pretty good price so I got two gallons. The brand is "Xtreme Blue". I opened one up tonight, it had the typical foil seal under the cap, but the fluid smells very bad. It smells like rotten eggs. The fluid is not discolored, is the normal pale blue color, it is the type for use only down to 32 degrees which is fine for us here in Florida. I was curious so I opened the other bottle, it also has a smell to it but is not quite as bad as the first bottle. I have never seen this before, usually washer fluid just smells like Windex. Does anyone know if this stuff is OK to use or should I dump it down the drain?
