Best Foam Sprayer for Pressure Washer Buying Guide

Taking care of your car requires having a pressure washer with a foam sprayer. The multiplicity of uses that these pressure washers have necessitates that you use a foam sprayer to get the ideal cleaning results. These foam sprayers create thick foam that takes away the grime and grease. Selecting the foam sprayer for pressure washers is not easy as there is a lot that needs to be taken into account. It is bearing that in mind that we have prepared this buying guide to help you choose the ideal foam sprayer for pressure washers in 2023.

What To Consider When Buying a Foam Sprayer for Pressure Washer?

There are several factors you need to consider before purchasing a foam sprayer. You can choose a foam gun from various options, but there are some things to look for when buying one. 

Size of the internal orifice

The most important factor to consider when purchasing a foam sprayer for a pressure washer is the size of the internal orifice. This should be matched with the nozzle size of your pressure washer. If the two sizes of the orifice are different, then you’ll end up with watery foam, pulsating foam, or a combination of both. Once you’ve figured out what your needs are, it’s time to look for a foam sprayer that matches them perfectly.

Size of the sprayer

The size of the foam sprayer is another important factor to consider. The larger the model you purchase, the better. If you’re planning on using it to clean cars, a small version will work just fine. But you need to think about the size of the area you want to clean. The smaller the area, the better. You’ll need a bigger one if you’re planning on using the foam sprayer for cleaning vehicles.

Compatibility

A good foam sprayer should be compatible with a high-pressure washer. The gas and electric models are ideal for cleaning vehicles. You should also consider the power of the machine, as this will determine the capacity of the foam sprayer. A dual-nozzle foam sprayer will be better for your needs, as it will allow you to adjust the foam stream.

What Are the Different Types of Foam Sprayers?

It is possible to utilize a pressure washer and various foam cannon attachments of varying quality to get the best possible surface cleaning results on your car.

Consumer-grade

These foam sprayers are suitable for use by the general public. Despite the lower quality of the parts, brass fittings may be used instead of stainless steel; the containers may not have a screw seal and gasket, as well as similar design alterations are often made to cut costs. It’s perfect for weekend warriors and occasional use. They’re also reasonably priced. These foam cannons have some drawbacks, including the fact that they might leak around sealing and stop performing properly after a while.

Professional-grade

Superior to consumer-grade sprayers, professional foam sprayers employ stainless fittings, a much more precise check valve, and higher-quality plastic bottle components than those found in consumer-grade sprayers. Prices range from $80 to $100.

What Are the Benefits of Using a Foam Sprayer for Pressure Washer?

You can create large volumes of suds

With a foam sprayer, you may create larger volumes of suds, which aids in the removal of dirt from the surface of a vehicle or other object that is being cleaned. When you’re done, the surface will be cleaner because of the increased volume of bubbles and soap. 

Reduces the likelihood of getting scratches on the car

When you’re utilizing a foam sprayer instead of a glove or sponge, you lessen or eliminate the risk of scratching your car.

What Are Some Tips To Use a Foam Sprayer?

  • Assemble your foam sprayer and begin to work cleaning it once you’ve decided on which foam gun to use. The foam cannon should be used only after the automobile has been washed with water to remove any loose particles and maximize its effectiveness.
  • The extension of most foam sprayers is attached with a simple fast connect. To foam your car, you’ll need a brief trigger pistol for the pressure washer, which you can attach to the foam sprayer. Fill the foam sprayer container with the cleaning solution of your choosing and warm water, making sure that the cleaning solution is thoroughly mixed before you use the sprayer.
  • It’s time to turn on the power washer now that you’ve connected the foam sprayer and filled the foam reservoirs.
  • To control the amount of foam emitted, turn this knob, which is normally located on top of the foam sprayer. The foam sprayer’s frontal end can be twisted to adjust the fan pattern’s size as well.

How Can I Use a Foam Sprayer to Wash My Car?

To begin, add a small amount of foaming car soap and warm water to the foam sprayer canister. As soon as that is done, reattach the canister to the foam sprayer. Afterward, connect the foam sprayer to that same pressure washer. The foam sprayer’s settings can be customized to your preference. To use an example, if your foam sprayer offers customizable stream patterns, you can pick the stream pattern you prefer. Maintain a distance of four feet first from the car while using a foam sprayer to lather your vehicle from top to bottom. After that, let it sit for some minutes before using it. Afterward, spritz the car clean with water and wipe it down.

Rinse your car afresh now that it’s undergone its first wash. You’ll need a wash mitt just after the second suds to remove the dirt off the car, so get one. The two-bucket approach is the best way to avoid scratching. Wash your automobile once more after that. Use a microfiber cloth after the final rinse to finish drying your car. The foam sprayer can be used again if you have any soap left in it when you’re done washing your car.
