Whole crops and vegetation can be severely damaged or worse still - totally destroyed - by traces of herbicides and residual chemical. Here are a few simple steps for you to follow to ensure your spray equipment is thoroughly cleaned to prevent any wrong chemical being sprayed. 

So, what tank-cleaning agent should I be using?

Commercial Tank Cleaners

These are ideal for removing water and oil soluble herbicides.

Household Ammonia

Recommended for penetrating and loosening residue in your spray equipment. Ammonia doesn’t actually decompose herbicides, instead, it increases the solubility of some herbicides by raising the pH.

Chlorine Bleach

Can be used to decompose residues of most sulfonylurea and other herbicides into inactive compounds.

WARNING! If chlorine bleach is mixed with a fertilizer that contains ammonia, it will produce a dangerous chlorine gas. This will irritate your eyes, nose, throat, and lungs.

Kerosene or Fuel Oil

This should be used to remove oil-based herbicide. After you have rinsed your tank with the oil, clean it further using detergent or ammonia.

Ok, so let’s begin….

hs-no1   Firstly, you want to ensure you are not about to flush out your tank in an area that will contaminate any water supplies or damage any vegetation
hs-no2   Ensure your tank is fully drained of any fluid and then simply rinse the inside by spraying it with clean water using a pressure cleaner or nozzle on your garden hose
hs-no3   Fill your tank up slightly with clean water and spray for about 5 minutes to ensure the spray boom is rinsed of any chemical residue
hs-no3   Turning the pump off, now fill up your tank once more with clean water
Add the correct amount of cleaning agent to your tank, based on the recommended measure given on the label

TIP! If you have an agitator, run it for 5 – 10 minutes to help mix the solution with the water inside the tank. If you do NOT have an agitator, just use a clean stick or tool

hs-no3   Once mixed, leave your sprayer for 8 hours to ensure any herbicide is removed from residue left within the tank
hs-no3   After at least 8 hours, turn your pump on and flush the cleaning solution through the boom and hand wand
hs-no3   Having flushed the solution, you must now clean the nozzles, strainers and screens by placing them in a bucket of water and cleaning agent
hs-no3   Time for one final rinse! Once all the nozzles etc are back in place, give the whole spray system a rinse down to ensure all the cleaning solution has been removed
