    The objective of this work is to evaluate levels of injuries caused by herbicides on sensitive plants after the spray tank cleaning process with different products, at two moments after the sprayer was used. A benchtop sprayer, consisting of a spraying system complexed with spray pump, mechanical stirrer, line filter, solenoid valve, flow meter, spray bar, six nozzles, tip filter and six spray tips was used. Water cleaners, Desadere, Invictus 01, Invictus 03, Invictus 04 and Invictus 05 were used. The sprayer was contaminated with 2,4-D at the dose of 1.5 L ha⁻¹ and Glyphosate at the dose of 2.0 L ha⁻¹. After cleaning with water two more cleaning steps were carried out with clean water in the same amount, characterizing the triple spray of the sprayer, this procedure being characterized as "Immediate". Samples of the liquid were collected at each stage of contamination and cleaning. These procedures were repeated after resting the syrup on the sprayer overnight (12 hours), overnight. Samples were collected throughout the washing phase, being applied on herbicide-sensitive plant (soybean). The results showed that Invictus 03 presented an overnight decontamination potential, but did not present decontamination potential in an immediate procedure. Invictus 04 and Invictus 05 presented a high decontamination potential of the spray circuit.
