I have done it by washing very thorough with water and ammonia. Run a tank or so through it and then straight water.

I contacted LMC direct and talked to them about a new pump and it's care. We have always cleaned it all well, and then pulled the pump off and put it in a bucket of oil by itself. The guy told us that could possibly eat the seals and o-rings. He suggested that we run water through it well and then run a gallon of anti-freeze through it. When it ran out and stopped spraying...stop. the anit-freeze has enough oil in it to lubricate the pump good and clean it as well

 

I just run water through mine after using it and never had a problem.

At the coop I work for, we triple rinse sprayer tanks and booms, and pull end plugs on the booms. Each rinse gets a recommended amount of tank cleaner/neutralizer

 

Triple rinse is the suggested method. We never used neutralizer, just rinse and run water through nozzles real good. I sprayed for years for the USDA.

 

They also sell a tank cleaner at most farm and home type stores.

 

Tractor Supply carry's a cleaning powder I think it's like $10. It will neutralize any chemicals in the sprayer. It takes about an hour to clean my 30 gal sprayer per directions. You fill the tank a little, add powder, then fill up to about halfway. Run neutralizer through the sprayer for the recommended amount of time.

Last time I ran glyphosate through my sprayer I just rinsed everything with water though. I will probably neutralize before I apply fertilizer in the fall.

 

I rinse mine out with water a few times, then let it out on a hot dry day to totally evaporate any liquid.

 

I clean mine out with water and a little dawn dishwashing liquid. I rinse it out twice (also through wand and nozzles) and it's good to go. Never a problem. I spray with weed killers, fertilizers, and pesticides but wash and rinse after each use.

 

I always just run a tank of clean water through it and that has always worked for me.

 

Triple rinse the tank with water. On the last rinse, make sure you use that water to flush out your re-circulating plumbing, if your sprayer is so equipped. Then pump it out through the booms. I might use tank cleaner once a year.

 

Run a lot of water through it and air dry

 

I rinsed after using gly and went to use 24d on my lawn and killed half of it. Hard lesson. I have separate tanks now. I only use backpack sprayers so it's cheap to have a few. One for compost tea strictly that never gets herbicides.

 

Ammonia works well for me

 

I use ammonia , then water and let dry.

 

Most custom chemical applicators are required to take a test to have a license (I had one 20 years ago as I spent 2 summers working on a research farm) and the Triple Rinse method is very standard in the industry. Rinse it out 3x then run the last rinse thoroughly through the lines and nozzles and you will be good to go.

 

I just run a half tank of water through it. To dilute any chemical that's in it and make sure the hose is clean. Then I fill it with the new stuff. I use my sprayer constantly from everything from 2,4D, glyphosate, simizine, clethodim, and yard pesticides such as sevin and permethrin. I've never had a problem.
