Rinsing time may vary, but 30 seconds is common. If containers are not clean, repeat the steps. Wilson urged that when pressure rinsing, make sure both the inside and the outside of the containers are rinsed clean. Protective clothing, as stated on the pesticide label, must be worn when rinsing containers, reminded Wilson. Containers should be rinsed as soon as they are emptied.
Some products are next to impossible to remove after they have dried on the container.
Containers should be clean and dry when brought to the recycling site. According to Hagen, caps and labels no longer need to accompany the containers as they have in past years. For the dates and locations the pesticide container recycling program will be in your area, contact your local county Extension office.
