1. Finish with an empty tank leaving all product in
the field.
2. Clean the sprayer in an area that will not
contaminate water supplies, streams, crops or
other sensitive areas and in an area inaccessible
to children, pets and livestock. Rinse equipment
thoroughly inside and outside removing any
visible product adhering to nozzles, tanks
and boom.
3. Fill the tank 1/2 full with water and the
herbicide-specific Rinse 1 solution from the
tables included inside this publication. Agitate
for 15 minutes.
Further information can be found in
Burn It Down, Clean It Up,
Extension Fact Sheet FSA2170
found at www.uaex.edu
4. Flush Rinse 1 through hoses, boom and nozzles
for 15 minutes, then drain.
5. Fill the tank with water and the Rinse 2 solution
(if applicable) while agitating. Let it set prefer­
ably overnight before flushing again.
6. After flushing system, disassemble and clean
all strainers, filters, nozzles, nozzle screens,
diaphragms and boom ends where residue
can accumulate.
7. Continue listed recommended rinses from the
table (Rinses 3, 4, 5 and 6) for selected herbicide
by filling, agitating and flushing the system with
the listed solution each time.
NOTE: Following the procedures specified on the
herbicide or commercial cleaner label is critical
to removing herbicide residue from the sprayer
system. This publication provides general guide­
lines for cleaning application equipment, but it is
important to remember that the best source of
information is the pesticide label and application
equipment manual. Consult labels of the prod­
ucts that were previously in the tank, and for the
products that will be used for the next applica­
tion, for specific cleaning and mixing/loading
instructions.
The University of Arkansas Division of Agriculture
recommends a minimum triple rinse for clean-out of
all herbicides regardless of label recommendations.

Also, many growth-regulating herbicides
can be particularly destructive to sensitive
crops even in extremely small concentrations.
Ensure proper clean-out by using proper

soaking procedures, and always refer to
product labels for any clarifications.
