Cleaning Pendimethalin stains off a sprayer boom?

[Shutesy]

My sprayer booms have got a nice yellow tinge to them since autumn herbicide spraying, having done a bit of research it seems I should have sprayed them with something like a oil/diesel mix before spraying to then wash off when I'm done but it's a bit late now.
Has anyone found anything that will get the stuff off without removing all the paint as well? I've tried scrubbing with Fairy liquid, no luck, and petrol on a washing up sponge, it started to come off but so did a nice blue tinge of paint so I stopped pretty quick. Anyone got any suggestions? I don't mind putting in a bit of elbow grease if needed if something will get it off. Has anyone tried BASF Neutralize?

G101, a cup of tea then a pressure washer on hot.... oh and a bio bed to catch the washings etc... done!

Cheers Rob, will try some of that, can do the washing into a biobed bit, can't do the hot pressure washer bit !

I've always just used petrol. Easier said than done, but best thing to do is wash it everyday when your finished.

Buy a yellow sprayer. Solves a lot of problems.

White plastic tank and wheels were never fun.

Sunlight eventually fades it too.

Have you tried a very strong solution of TFR? Got the ratio a little off once when washing trailer after chicken poop.. there was green water running off it down the yard

Petrol on a rag then tfr then spray with oil before next time works a treat.

I spray on some rape oil with knapsack before spraying then just wash off when finished.
