Wolfgang foam cannon not foaming

[01GreyStangGT]

The last 2 times I have tried to use my foam cannon, it is not pulling the soap from the tank into the gun. The time prior to this I may not have flushed it with water properly. I took q-tips and ran them into the nozzle after removing the intake tube. They came out dirty but cannon still doesn’t work.

Ideas on bringing it back to life?

Are the seals and o-rings in good working order?

They should be. I don’t use it very often. Will look tomorrow.

Possibly a clogged mesh filter?

I had a similar problem with all 3 of mine after several years of use. Took them apart and soaked the mesh filters in some CLR overnight. Rinsed them the next morning and they were working great again. If that works I would suggest just buying a few extra mesh filters and have them on standby in case it happens during a detail and then you can just replace and keep on foaming!
