When it comes to water-fed window cleaning, choosing the right type of jet-pencil or fan-can make a significant difference in both efficiency and results. Pencil jets offer concentrated, high-pressure stream of purified water, ideal for tackling stubborn dirt and grime on windows. In contrast, fan jets disperse water over a broader area, making them more suitable for covering larger surfaces, quickly and providing a more even rinse. Understanding the differences and benefits of each can help window cleaners tailor their approach for optimal cleaning performance depending on the job and type of glass at hand.

Before we dive into which style jets would suit your needs best, it’s important to consider the type of glass you’re working with-hydrophobic or hydrophilic. The way water behaves on these surfaces greatly influences which jet will deliver the best results. By understanding how each type of glass interacts with water, you can better determine whether a concentrated or broad-spray is ideal for achieving a streak-free, spotless clean.

Hydrophobic vs. Hydrophilic Glass

Hydrophobic glass repels water, causing it to bead up and roll off the surface. This behavior can make it more challenging to achieve a streak-free finish, as the water beads can leave marks as they dry. With hydrophobic glass, extra rinsing may be needed to ensure all dirt and minerals are thoroughly washed away to prevent spotting.

On the other hand, hydrophilic glass attracts water, causing it to spread out evenly in a thin sheet across the surface. This allows for a more even rinse, reducing the likelihood of water spots or streaks. Hydrophilic glass tends to be easier to clean with a water-fed system, as the water distributes more uniformly, allowing dirt to be rinsed off more effectively.

The difference between these two types of glass affects how water behaves on the surface and, consequently, the technique and effort required for a spotless finish.

Pencil vs. Fan Jets

Pencil jets offer several benefits when used for water-fed window cleaning, particularly for tackling tough grime and reaching into detailed areas. Their narrow, concentrated stream provides higher water pressure, making it easier to dislodge stubborn dirt, bird droppings, or mineral deposits. This targeted cleaning is especially useful for windows with hydrophobic glass, where water beads up and can leave streaks or spots if not thoroughly rinsed. Pencil jets also give you greater control, allowing for precise cleaning inside the window frames, corners, and edges where dirt tends to accumulate. Overall, pencil jets are ideal for detailed, intensive cleaning tasks that require a focused rinse.

Fan jets offer distinct advantages for water-fed window cleaning, especially when working on large windowpanes or hydrophobic glass. Their wider spray pattern disperses water evenly across the window, making it easier to cover more area in less time. This broad rinse is particularly effective for windows that sheet water, allowing dirt and debris to be washed away smoothly without leaving streaks or spotting behind. Fan jets also reduce the risk of over-wetting or using excessive pressure, making them ideal for more delicate surfaces or frequent maintenance cleans. For jobs that require speed, efficiency, and a more uniform rinse, fan jets are the preferred choice.

As you can see, both types of jets offer unique benefits, and understanding when to use each can help ensure optimal cleaning performance. Pencil jets are ideal for concentrated, high-pressure cleaning on stubborn dirt and hydrophobic glass, while fan jets excel in providing a smooth, even rinse on large surfaces and hydrophilic glass. By considering the type of glass and the level of grime you’re up against, you can choose the jet that best fits the job, ensuring a faster, more effective clean every time. Ultimately, having both options available equips you to handle any cleaning scenario with confidence and precision. If you use Gardiner brushes, you may want to consider checking out the Gardiner Brush Jet Capsules. Each capsule has a unique spray based on your needs and spray preferences.
