A hot water pressure washer can be a powerful ally in the fight against dirt and scum. Generally used outdoors, hot 
water pressure washers are an upgraded version of your standard washer. While most models are big and expensive, there are some available designed for everyday consumers. These models are considered to be top of the line, using heated water to scour through any type of dirt. As an added bonus, the heated water can kill bacteria and germs, such as those which accumulate and grow on wooden furniture. More common uses include cleaning sidewalks and driveways, or even the stucco on your home’s walls. Nonetheless, any pressure washer is only as strong as its weakest component. Let’s take a look at some of the basic types of maintenance you can do to keep your hot water/ steam pressure washer running for years.
Step One
A hot water pressure washer has a chemical intake tube which users pour cleaning chemicals into. These chemicals flow out of the sprayer with the water, working to break down dirt. However, leaving the chemicals inside the intake between uses can lead to internal corrosion. This problem can become especially prominent when the washer is left in storage for long periods of time. To remedy this, simply pour water into the chemical reservoir and run the machine for a few minutes until the chemicals are flushed out. This simple step can save you a lot of hassle and repair costs.
Step 2:
While the hoses on these washers are very durable and able to withstand high pressure, one must remember that constant pressure can cause any material to bow and flex. Leaving the built-up pressure inside of the hose can expand the hose over time, resulting in unneeded replacement. Also, mechanisms inside the hot water pressure washer can be damaged by endless pressure. After every use, be sure to press the nozzle to release any stored pressure. This quick step can keep your hose like new.
Step 3:
After these units are turned off, water becomes trapped inside of the pump until the next use. To get the water out, pull your starter cord a few times while keeping the nozzle open. If you have an electric model, press the starter switch a few times, holding for a few seconds each. This step serves to prevent rust and eliminate pump-bound hard water corrosion. Hard water from the tap line has minerals such as calcium which build up when dried.
Step 4:
When done for the day, remove any drain hoses from the hot pressure washer. This allows any excess water to drain out completely and not get trapped in the hoses. The more water you can remove from the washer, the better. Always store the washer in a dry location, such as a garage or storage shed.
Step 5:
If money is tight, leaking hoses can be repaired with certified patch kits. However, one should only make these repairs when the unit is turned off.
Step 6:
Not using the washer while it is turned on is a quick way to cause overheating. A hot water pressure washer can overheat if not used within a few minutes. For maximum pump lifespan, either use the machine or turn it off.
