Which chemical is recommended for cleaning tanks containing hormone-type herbicides?

The recommended chemical for cleaning tanks containing hormone-type herbicides is ammonia. Ammonia is effective in breaking down these herbicides, which are often persistent and can leave residues that interfere with subsequent applications or contaminate other products.

When cleaning tanks, it's essential to use a cleaner that will thoroughly remove these residues without reacting negatively with the materials of the tank or the herbicide itself. Ammonia effectively neutralizes and washes away the compounds found in hormone-type herbicides, ensuring that the tank is clean and ready for the next use.

In contrast, other options, such as chlorine, bleach, and vinegar, are not suitable for cleaning tanks that previously contained hormone-type herbicides. Chlorine and bleach can produce harmful byproducts when mixed with certain chemicals, potentially leading to dangerous reactions or ineffective cleaning. Vinegar, while useful as a mild cleaning agent, does not possess the strength needed to effectively remove hormone herbicide residues from tanks and equipment. Thus, ammonia stands out as the correct choice for this specific cleaning need.
