How many times should you dilute and flush the tank with water before using a cleaning solution?

Diluting and flushing the tank with water before applying a cleaning solution is a crucial step in ensuring that any residual pesticides are adequately removed. Flushing the tank twice helps to ensure that any remnants from previous applications are sufficiently diluted and expelled. This process minimizes the risk of cross-contamination, which can occur if residual chemicals are mixed with the cleaning solution or another pesticide.

The practice of flushing the tank two times is typically based on standard protocols that offer a balance between efficiency and thoroughness. Flushing once may not fully remove all residues, particularly those that may cling to the inner surfaces of the tank or hoses. On the other hand, flushing more than two times can be unnecessarily wasteful in terms of water usage and may not provide significant additional benefits in terms of residue removal. Thus, flushing twice strikes an effective compromise for achieving a clean tank before introducing a new cleaning solution.
