Next time you throw one away, pause for a moment of respect. You are not discarding junk. You are exiling a tiny, stubborn, ingenious machine that lost a battle against a grain of dried Windex, a bubble of air, or a microscopic gap in a rubber seal. And if you really want to win, unscrew the head, soak the nozzle in hot vinegar, clear the dip tube, and give it one more slow, deliberate pump. You might just resurrect a ghost.
Open the bottle and verify the plastic straw (dip tube) is firmly attached to the pump head and reaching the liquid. spray bottle pump not working

Remove the spray head and soak it in warm water (below 70°C) for 10–15 minutes. And if you really want to win, unscrew
First, appreciate what should happen. Inside that unassuming head is a marvel of miniaturization: a tiny piston cylinder, a spring, and two one-way gates known as check valves. When you pull the trigger back, the piston retracts, creating a vacuum in the cylinder. The lower check valve (submerged in the dip tube) opens, and atmospheric pressure—that invisible giant—pusches the liquid up the straw and into the chamber. When you release the trigger, the spring pushes the piston forward, slamming the lower valve shut and forcing the liquid out through the upper valve, past a tiny swirl chamber, and out the nozzle as a fine mist.
