Sprayer out of hibernation

[oakleaf]

The sprayer had 10 litres antifreeze circulated all around before being shed stored for the past 4 months.
Going to spray a tank of Roundup next week (2000 litres).
Best practice is probably to give a rinse out but is it really necessary before using roundup?

I’d give it a rinse. You don’t want the antifreeze killing the grass when you put the roundup on

keep the anti freeze for next year just top it up with fresh. quick rinse through to make sure all is working ok and nozzles are good. then go spraying
