I first thought I owned a Riccardo Foam Cannon but after closer inspection it's just a MTM Hydro. Basically I saw PB's new foam cannon video and decided to clean my foam cannon.
What you'll need for this
This is the first pin you need to push out with your small diameter tool
Now slowly YANK the black spray adjuster out
Next take your 7/8th inch spanner and grab hold of the the brass thing you see in the picture
After you release the initial tension you should be good to just loosen away by hand
Can you see the little metal filter inside that piece
I use the end of a L key to push it out
Pop, it came out
Can you guys see that filthiness
Next put that piece inside disposable bowl, if you have a plastic one it's way better as I found out that CLR eats away at these things so I
changed it
Make sure you coat everything
Here I changed the bowl
After 12 hours of dewll time
I then ran it under warm water with an old toothbrush to really make sure I got it clean. It's good as new now
