Weedwiper clogging up!

[It was already broken.]

I got a new weedwiper from Logic to tow with the quad this season. I used it with MCPA (pasture master) a few weeks ago no problem. Put some roundup through it to do rushes and some thistlex. Now I am back on MCPA the chem seems to 'curdle' in the tank and block up the filters and nozzles within 10 minutes. Clean it out with water and washing up liquid and get it all running but as soon as MCPA back in the same thing happens. Any ideas? I assume some contamination but I have not had this with a sprayer. Anything I should be adding. Nettles have gone mad and the sheep can't eat the grass quick enough this year so can't just put roundup through as the grass is too high. Anyone else had this? Thanks

Can you not just boom spray MCPA too do a quick control and then stick too Glypho in the wiper? I’ve never had issues with mine other than the blue dye we used once on a national trust job. That was horrible gummy crap too clean out

No you didn’t youve only ever put glypho through it as it’s the only approved chemical….

on another note have you tried tankwash?
