Okay, so today I finally got around to trying out that soap cannon I bought for my pressure washer. Been meaning to do it for ages.

Getting Started

First thing, I dragged the pressure washer out of the garage. Hooked up the water hose, plugged the power cord in. Standard stuff. Then I grabbed the soap cannon attachment. It's basically a bottle with a fancy brass nozzle thingy on top.

I unscrewed the plastic bottle from the nozzle part. The instructions said something about ratios, like how much soap to water. Honestly, I just kinda eyeballed it. Poured in some car wash soap, maybe about a fifth of the bottle? Then I topped it up with warm water from the tap. Gave it a little swirl, not too much, didn't want to make a bubble bath inside the bottle already.

Attaching the Cannon

Screwed the bottle back onto the brass part nice and tight. Then I took the regular spray wand off my pressure washer – you know, the quick-connect fitting. Popped the whole soap cannon assembly onto the end of the pressure washer gun. Clicked right in. Felt pretty solid.

Foam Time!

Alright, moment of truth. I pointed it at the car (yeah, the poor thing was filthy). Squeezed the trigger on the pressure washer. WHOOSH! Foam everywhere! It was pretty cool, not gonna lie.

Now, there's a knob on top of the cannon. I twisted that around a bit. It changes how much water mixes in, so you can go from runny soap to thick shaving cream style foam. Found a setting I liked, thick enough to stick but not ridiculously thick.

There's also the nozzle at the very front you can twist. That changes the spray pattern, from a narrow stream to a wide fan. I set it to a wide fan to cover the car quicker.

The Wash Process

So, I just went panel by panel, covering the whole car in a nice white blanket of foam. Started from the roof and worked my way down. It clings pretty well.

• Covered the roof.
• Did the hood and trunk.
• Got the sides, windows, everything.
• Didn't forget the wheels.

Let the foam sit for a few minutes. The idea is it softens up all the dirt and grime. You could see some of the dirt starting to drip down with the foam. Looked promising.

Rinsing Off

After maybe 5 minutes, I disconnected the soap cannon. Popped my regular rinse nozzle back onto the pressure washer gun (used the white or green one, can't remember, the one with a decent fan spray but not the super aggressive one).

Then I just rinsed the whole car down, again starting from the top and working my way down. All the soap and dirt just washed away. It was pretty satisfying watching the grime disappear.

Finished rinsing and took a step back. Yeah, it worked pretty darn well. Much better than just using the regular soap nozzle on the pressure washer, which is usually pretty weak. This foam cannon thing actually covers the car properly.

So yeah, that was my first go with the soap cannon. Pretty straightforward, actually. Made washing the car a bit quicker and honestly, a bit more fun. Definitely gonna be using this thing regularly.
