What to Consider In A Pressure Washer for Aluminum Siding
There are several factors to consider when choosing the best pressure washer for aluminum sliding. In fact, these factors will help you to determine what task a machine is best suited for and how well it performs. Now, what are those factors that you should check out?
Power Source
When we talk about pressure washers, power is of utmost importance. You'll want to check out how different models are powered. The most popular are electric, and gas models, and each comes with its own benefits and drawbacks.
Gas-powered machines are typically expensive, but more powerful than electric ones. There are suitable for heavy-duty jobs around your home. Electric powered, on the other hand, are pretty cheap, easier to maintain, and lighter.
Moreover, they operate quietly without creating any disturbance and harmful air pollution. These are suitable for small projects. However, both will perform when it comes to cleaning aluminum siding on the house.
Water Pressure
Another critical feature to consider is water pressure. When buying your model, you'll have to jot down the amount of force the pressure washer creates. Keep in mind pressure that goes hand in hand with cleaning power – more pressure means more cleaning power.
Mathematically, water pressure is measured in Pound per square inch (PSI). But this doesn't mean that you shop for any highest PSI model you come across. It will depend on what you intend to do with the machine. Any machine that starts at around 2,000 PSI up to 3,000 PSI is suitable for tackling aluminum siding. But keep the pressure in the 300 to 500 PSI range to eliminate any damage.
Gallon Per Minute (GPM)
The next key factor, which is closely related to PSI, is the GPM (Gallon Per Minute). This means the volume of liquid going through the pressure washer. PSI and GPM are directly correlated. When the pressure is high, the machine will use more water per minute.
A pressure washer with a high GPM will clean effectively and faster. In our case, aluminum siding requires more water to fully clean built-up dirt, mildew, and stains. A machine that uses 2GPM up to 4GPN will maneuver.
Motor & Engine
A motor is an essential part of a pressure washer. It exerts the power required to run the machine. A powerful motor is enough to deliver decent performance.
The engine is the heart of your pressure washer. Like how a healthy heart is vital for your body, the engine determines how powerful and amazing an electric pressure washer is. For example, Simpson Cleaning MSH3125 comes with a powerful Honda GC190 residential engine for reliable power.
