Well I recently rejetted my Foam canon to a 1.1mm jet. Using it with a small electric power washer. Ryobi 1600psi 1.2gpm

I tested this with 2oz to the bottle of my MTM Foam canon.

Then 2oz to a half bottle (equivalent to 4oz )

I loved the foam I was getting. And the smell of grapes was very nice. I definitely got more foam with the 4oz ratio. But 2oz was impressive.
It left no water spots and rinsed off easily.


I think If I still had a gas power washer I would have had a much thicker foam.
