Is your air cooler running at maximum fan speed but only throwing sticky, humid, warm air? The problem isn't the motor—it's a hidden white crust inside.

Using hard tap water creates a massive buildup of lime-scale (calcium deposits). This white crust clogs the internal water pump, spray lines, and cooling pads.

Lime-scale chokes the tiny air gaps in your cooling pads. Water can no longer evaporate properly. The result? Your cooler uses full electricity but stops cooling your room.

Do not use harsh chemical acids—they will melt your plastic cooler body and ruin the pump. Instead, use cheap white kitchen vinegar. It dissolves hard minerals naturally!

Remove the back panels and pull out the cooling pads. Mix equal parts vinegar and water in a bucket, spray it heavily over the pads, and let it sit for 20 minutes.

While the pads soak, pour a cup of vinegar into the empty bottom tank. Take an old scrub brush and watch the stubborn white crust wipe away cleanly.

Take a small safety pin or piece of wire and poke through the tiny water holes on the top tray. This ensures water drips evenly across the pads again.

Wash everything thoroughly with clean tap water to remove any leftover vinegar smell. Pop the pads back into the panels and lock the cooler shut.

Now, your pads can hold water perfectly and airflow is fully restored. Your air cooler will instantly throw crisp, ice-cold air and reduce indoor humidity!
