Corrosion Risk

Using Tsp (trisodium phosphate) in a pressure washer can pose a potential risk of corrosion. Although Tsp is commonly used as a cleaning agent due to its effectiveness in removing grease, oil, and grime, it is also highly alkaline.

When Tsp comes into contact with metal surfaces, especially those made of aluminum or steel, it can cause corrosion. The alkaline nature of Tsp can react with the metal and degrade its protective oxide layer, making it more vulnerable to rust and corrosion.

Aluminum

Pressure washers often have aluminum components, such as the pump housing or pressure wand. These aluminum parts may be particularly susceptible to corrosion when exposed to Tsp. If the oxide layer on the aluminum surface is damaged, the metal can start corroding, leading to pitting or discoloration.

Steel

Steel surfaces, such as the frame or fittings of a pressure washer, can also be at risk of corrosion when Tsp is used. The alkaline nature of Tsp can react with the iron in steel and accelerate the corrosion process. This can result in rust formation, which weakens the structure and can lead to leaks or failure over time.

To minimize the risk of corrosion, it is advisable to avoid using Tsp in a pressure washer unless it is explicitly recommended by the manufacturer. Instead, opt for cleaning agents that are specifically formulated for pressure washers and are less likely to cause corrosion.

If you do use Tsp in a pressure washer, it is crucial to thoroughly rinse the equipment after use to remove any residue that could potentially cause corrosion. Regular maintenance, including inspecting for signs of corrosion and promptly addressing any issues, can also help prolong the lifespan of your pressure washer.

Remember: Always consult the manufacturer’s instructions and guidelines regarding the use of cleaning agents in your pressure washer to avoid any potential damage or voiding of warranty.

Damage to Pressure Washer Seals

One of the potential risks associated with using TSP (Trisodium Phosphate) in a pressure washer is the possibility of damaging the seals in the machine. Pressure washer seals are typically made of rubber or similar materials and are designed to create a tight seal between different parts of the equipment, such as the pump, hose, and nozzle.

While TSP itself is not inherently harmful to pressure washer seals, it can cause damage if used incorrectly. One common mistake is using a solution that is too concentrated, which can lead to chemical reactions that degrade the rubber seals over time. It’s important to follow the manufacturer’s instructions and dilute the TSP solution properly to avoid any potential damage.

Another factor that can contribute to seal damage is excessive pressure. Pressure washers are designed to operate within specific pressure limits, and using excessive pressure can put strain on the seals, causing them to wear out or fail prematurely. It’s important to use the pressure washer within its recommended pressure range and avoid applying excessive force to prevent seal damage.
