For Slow or Clogged Drains: Slow-running showers and bathtubs are a common problem, Luigi's Drain Cleaner solves it - always. Apply directly to the drain and after a few pumps, standing water will be a thing of the past. Clean Clogged Sinks Quickly: Place the large opening of the drain cleaner over your clogged drain and pump twice. You will clean more in 10 seconds than with any other type of drain cleaner. Guaranteed Very Powerful: The power comes from the pressure you apply to the bellows while it is on the stopper, forcing trapped air down the drain hole. It's the same method as a traditional drain cleaner, but with 8 times the air volume. When you're done, simply spray it with bleach and rinse it under water. The head is removable for easy storage. Pro Tip: If you are cleaning a sink or bathtub with an overflow, plug it with a damp cloth before you start pumping. This prevents air from escaping and makes the process even faster and more efficient.
