A pressure washer nozzle is the part of the pressure washer that exerts water pressure. Pressure washing is good for cleaning your home, your sidewalks, driveway, and even your car. You must use the washer correctly to avoid damaging the surface of whatever you are washing.

Step 1 - Select a Nozzle

Pressure washer nozzles restrict the flow of water creating water pressure. There are two kinds of nozzles. One is the quick disconnect nozzle and the other is a threaded nozzle. Quick disconnect pressure washer nozzles have a male plug that fits into a female couple on the wand. The nozzles are color-coded by the kind of fan spray they make. A red tip is a zero-degree nozzle.

These do not make a fan spray but spray in a point. It has the strongest impact and can damage some surfaces. It is good for cleaning strong surfaces. The yellow tip (chiseling tip) makes a fan pattern of 15 degrees. If you want to use it as a scraper, then you hold it at an angle. A green tip has a 25-degree fan pattern. This tip is for cleaning such as cleaning the leaves off of the sidewalks. Lastly, the white tip has a 40-degree fan pattern for delicate washing such as washing your car or washing wood. Select the right tip for your project.

Step 2 - Attach the Nozzle

Attach the nozzle to the wand and be sure it is securely attached. You can also add extensions to reach further or for water brooms.

Step 3 - Clean Chemicals

If you are using chemicals in your project there are special nozzles with a black tip you can use for these. These nozzles add the chemical after the water comes out of the pressure washer. These are low-pressure nozzles and spray in a wide fan pattern. Check the owner’s manual to see how to add chemicals and which ones are right for your pressure washer.

Step 4 - Protect Yourself

Pressure washer manufacturers recommend you wear clothing to cover your skin, protective eye goggles and gloves. Depending on how much noise the pressure washer makes you may want to wear ear plugs as well.

Step 5 - Do a Test Spray

Turn on the pressure washer. Do a spray to test the washer. Start in the air to the side of the item you are cleaning and then move the wand toward the object. Check to see if is working properly. If not, move closer.

Step 6 - Clean the Item

When it is working well, spray in slow passes until the item is clean. If you are using chemicals let them sit on the surface for a few minutes and then rinse.

Once you have used a pressure washer you will find more uses for it around your house. It makes short work of many of the cleaning projects that keep your home looking its best.
