Iowa Pesticide Applicator Practice Exam

What is recommended to use for cleaning pesticide equipment that contains residues?

1. Only water

2. Household ammonia, trisodium phosphate cleaner, or commercial tank cleaners

3. Vinegar and baking soda

4. Hydrogen peroxide

The correct answer is: Household ammonia, trisodium phosphate cleaner, or commercial tank cleaners

Using household ammonia, trisodium phosphate cleaner, or commercial tank cleaners is recommended for cleaning pesticide equipment that contains residues. This is because these substances are specifically effective in breaking down and removing pesticide residues from surfaces. Household ammonia is a strong cleaning agent that can dissolve various types of organic material and chemical residues, making it a suitable choice for such applications. Trisodium phosphate is known for its ability to effectively cut through grease and grime, while also being able to interact with chemical residues. Commercial tank cleaners are specially formulated for the cleaning of pesticide application equipment, ensuring that residues are effectively removed to prevent cross-contamination with other products. In contrast, while water can flush out some residues, it may not be sufficient on its own to completely remove pesticide residues, especially those that are more persistent. Vinegar and baking soda, while popular for general cleaning, may not adequately address the specific residues from pesticides. Hydrogen peroxide can be useful as an antimicrobial agent, but it is not designed specifically for cleaning pesticide residues from equipment. Thus, options like household ammonia, trisodium phosphate, or commercial tank cleaners are preferred due to their effectiveness in removing these potentially harmful substances.
