Typically, there's a two spurts of water shown on the cap. Once you found it, remove it from to container for further inspection. When you see plenty of holes and cracks, replace the cap immediately.

When you noticed that you need to exert extra effort in removing the cap, it's possible that the cap threads are severely damaged. You'll notice this particular problem when you're refilling the washer reservoir. If the cap is stuck, you might need to put ample amount of oil to loosen the cap a bit.

Clean the cap and the container's opening to prevent the cap from getting jammed.

Loose cap

This issue is the exact opposite of the previous one. A cap may also get loose due to severe mechanical vibration inside the hood. When the cap is not installed firmly, the washer fluid can leak out of its container. This can damage the engine as well as the other components under the hood. To check if the cap is wobbly, twist it slowly. If the cap comes off easily, twirl it in a counterclockwise direction. Twist it a bit harder to tighten its mounting.
