Hello everyone,

I bought this foam cannon gun to use with a 2300 PSI pressure washer. I used it for the first time today with Griot's Garage Brilliant Finish car wash. All I got was some bubbly soapy water, even less suds than a Gilmour Foammaster II. I diluted the entire bottlw 1/4 cup of soap. I was expecting extremely foamy (almost like a shaving cream) suds but what i got was very lame compared to the pics I 've seen on this forum.

What am I doing wrong?

Maybe it's too much to ask for a $20 foam cannon to be decent? A few of the reviews mention quality problems.

I'd say you need a smaller orifice. Foam cannons have an orifice which is what adjusts how much water flows through the foam cannon. Bigger orifices are used for more powerful pressure washers and smaller orifices are used for less powerful ones. I'm guessing the orifice in yours is just too big for the amount of pressure/gpm your pressure washer outputs. A 1.1mm orifice is what's recommended and you can get them for like $5 on amazon. You can easily change these by just unscrewing the back of the foam cannon off and then unscrewing the orifice with a flat head screw driver. There's plenty of youtube videos out there showing this so I'd say its worth a shot. I have a weak electric pressure washer with that same foam cannon and the 1.1mm orifice makes it foam like a powerful gas pressure washer

My guess would be that you're either using it wrong or it's defective. I bought a similar foam gun from Amazon and mine works just fine (used it with Meg's Gold Class soap and CG Honeydew soap and an 1800 PSI washer). Make sure the nozzle is adjusted to be more narrow, then play with the **** on the top to try different mixture settings and see what works for you.

It sounds like you added plenty of soap for it to work, so if you've already tried the above, it's probably a defective unit.

Can you post a link to the orifice on Amazon you're referring to?

Hate to see people using inferior products on vehicles. If you TRULY love your Lexus, go for it and get this Foam Cannon

Also- its imperative that you use a quality Soap as well. Since my whole car was done w PPF & Ceramic Coat - this is all I use....

GTechniq Wash

I guarantee that these two items will make your Auto Care MUCH more enjoyable and provide MUCH better results as well. (I even use a Greenworks PW from Lowes and these work awesome!)

You can use the highest quality foam cannon but they all will do the same thing. I actually have both the twinkle star foam cannon OP uses and the Mtm Pf22 and honestly they’re both relatively the same thing. With the 1.1mm orifice they both produce the same thickness of foam but the twinkle star just goes through the bottle faster than the pf22. Most foam cannons are the same Chinese product stamped with a different label. The $90 chemical guys ones are literally the same as the $15 ones on amazon. If you want crazy thick foam just get a powerful gas pressure washer. But using a high quality soap is definitely imperative

I bought and used the 0.1mm orifice and it made a bit of a difference, but not much. Perhaps I am expecting the foam to be much thicker than it really is in real life (as opposed to marketing/advertising pictures). Or maybe I need to switch the soap to something that produces thicker foam with a foam cannon.

The soap plays a big part in the thickness of the foam. That's why certain brands sell a foaming soap and regular car wash soap.
