Hi there, It appears I've stuffed up, I used my knapsack weedkiller 6 months ago & now looking to get back ontop of my weeds - but I did'nt flush the hose after use. Bugger.

Does anyone have any ideas on how I could dissolve, or any other way remove the weed killer that is now hard in the hose.

I've tried to poke with wire, but with no success as the pump wont, well, pump!

Thanks for your input have a good one.
AJ
