Save our sprayer. Got caught by rain 4 days ago with roundup and express in tank. Sat for 2 days. Now have a film on bottom third of tank that flush, merge and ezmix and 2 days work cannot remove. Any help would be greatly appreciated.

If tank empty.use pressure washer.

That sucks. What does the inside of the booms and hoses look like? If its just the tank I agree with the pressure washer.

Try all clear and leave it sit for a half a day in tank/booms. another option is liberty

Hoses, booms, screens all clean, did leave flush overnight

[Grahamp]

I agree try using liberty. Best tank cleaner there is.

Liberty works good.
Might have to get long handle
Mop of some sort but I'd be Leary of the booms and all the connections where ther is a lip where the fitting goes into hoses.

liberty , for sure

Liberty for after the fact. Dawn dish soap, couple second squeeze in every tank will prevent it in the first place.

Trying all clear overnight, if that doesn't work, liberty tomorrow. Thanks for advice.

I would use a very strong ammonia solution and even a strong detergent.

Fill the tank well above the mark where the residue is. Circulate with the bypass, tank rinse and recirculating/sparge valves open. Manually increase the pump pressure with the controller. Let run for a long time. Close bypass, tank rinse and sparger valves. Spray some of the solution through the booms(open previously closed valves)....let sit overnight(make sure solution is higher than the residue mark). Spray more through the booms the next day. Dump rinsate and make sure valves are open so no rinsate is trapped behind them. If your nozzles have screens, booms have line strainers clean them along with the main filter. Rinse twice with clean water after that(booms too).

DYODD.... Good luck. The ammonia is supposed to help break down or neutralize group two residue. The detergent will probably foam like a bitch...use defoamer.

ps..."Finish" is an ammonia based tank cleaner.

Edit, in some cases it amazing how little pesticide is needed to do its job....so a bit of residue or poorly cleaned tank, even if it didn't sit with product in for four days, could cause damage.

How about plumbing a suction line from your tank drain to a trash pump intake on water trailer, use a high rate of cleaner with 30 gallons of water and use a firehouse from trash pump to blast the shit out of the tank and recirculate the cleaning agent?

Our stainless steel Gator tank has a major baffle built in that would make pressure washing tough to do well.

Flush and merge overnight seemed to clean it fairly well. Will add all clear overnight tonight.once again thanks for help
