Why tank cleanout is a yield and liability issue

Residue left in tanks, lines, screens, and booms can injure the next crop—especially when you switch from a tough herbicide to a sensitive crop pass. Knowing how to clean a sprayer tank is as important as knowing how to mix one.

Labels for many herbicides spell out cleanout steps. Treat those directions as required, not optional.

A field-ready cleanout rhythm

Flush with clean water promptly after spraying. Remove and clean end caps, screens, and strainers. Use a labeled tank cleaner when switching chemistry families or moving to a sensitive crop. Circulate through the entire system, including boom ends.

Repeat rinses matter more than one long rinse. Dispose of rinsate legally—never into ditches or tile inlets.

Special cases that need extra attention

Dry formulations, oily adjuvants, and certain herbicides cling longer. If you parked the sprayer overnight with product residue, expect a harder cleanout. Keep a written cleanout log for rented or shared equipment.

Ask Roush Ag Solutions about tank cleaner options that fit your product rotation, and always follow the cleaner and herbicide labels together.

Always verify rates, crops, tank-mix partners, and restrictions on the product label and SDS before you spray. This article is educational guidance for Midwest farmers—not a substitute for label directions or local agronomic advice.
