Leaking winshield washer fluid bottle

Does anyones washer fluid bottle spill out the top? Fluid has been dissapearing from mine, and theres blue stains all around it..I took it off and filled it with water in the sink but didnt see any leaks..So I think it might be spilling out the top

Mine does a bit, usually when I bounce it around a bit... you have the cap still right? It doesn't do anything I would call "sealing" but it does help keep the splashing down.

If you're missing the cap, or the bottle has a crack in it or something, sounds like time for a run to the junkyard.

If all else fails you could swap it out for your coolant bottle. Then, you would have a coolant leak like most everyone else.
