Washing a car with a foam gun isn’t hard anymore. To get the best result, you have to use foam correctly all over the car. 

How to use foam gun

Step 1 – Fill the gun tank

First, you should fill the foam gun tank with suds. The mixing process is easy but may vary from device to device. You can follow the device instructions for this. Then attach the hose with the foam gun.

Step 2 – Rinse off the car

To wash away the loose debris and surface dirt, rinse off your car with only plain water. It’s a pre-process to make the car ready to apply foam. You should never apply it to a non-lubricated surface or dry car.

Step 3 – Apply a layer of foam

Now apply a thin layer of foam to the car body, window, door, gaps & cracks. You can divide it into sections like door panels, trunk, or hood. Which will be helpful to clean fast and easily. Keep the foam for 20-30 seconds.

Step 4 – Rinse off the foam

After a while, rinse off the car with clean water. In this step, you should not rub the car. 

Step 5- Apply another layer of foam

Again, apply a layer of foam on the car surface. It’s like step 3 except using a soapy wash mitt to remove dirt off the car.

Then rinse off the car properly. You are ready to go now with a shiny clean car.

Step 1 – Fill foam cannon reservoir

First, fill the foam cannon reservoir with 3 to 5 ounces of car washing soap. Then fill the rest of the reservoir with clean water. Now shake to mix them well. 

Step 2 – Remove loose dirt 

To rinse the loose dirt on the car surface, rinse with plain water first. We recommend using a car-safe pressure washer tip for this.  It will clean your car properly without any damage.

Step 3 – Apply the layer of foam

After rinsing the vehicle, attach the washer tip with the foam cannon. Until you get the desired amount of foam, you need to rotate the top knob to “positive”

It is useful to wash cars with a spray pattern. To achieve this, rotate the foam cannon nozzle that will cover the surface of your car properly.

Then spray on the car and let them sit on the car body for a few minutes. Rinse it with clean water. 

If your car is heavily spoiled, you should go for washing by mitt. In case, the bucket dirt trap is needed to place in the bottom of the bucket. Fill ¾ of the bucket with water. Then throw the wash mitt on the dunk. 

Step 4 – rinse off the foam

Now the cleaning time. As the lower part of the car is dirtier and spoiled, it’s good practice to start working from the top part to the bottom. 

Do not rinse at circular motion, always work at straight-line motion. Because circular working motion can cause scratches and swirl marks on the car finish.

Step 5 – Drying process

It’s the final step you need to finish. Once all of the foam is rinsed off, you need to go for the drying process. Otherwise, the water spots may fall on the car.

Take the drying towel and lay it on the car surface. Pull it in in a straight direction to prevent the falling of scratches and swirls. In addition, you can use a double-sided microfiber drying towel to dry your car properly. 

You should continue until you notice no streaking occurrence on the car.
