What is the CCM (Chemically Correct Mixture) ratio?

Explanation:
Mixing ratio tells you how much concentrate to combine with a given amount of diluent to reach the right strength. For a CCM ratio of 1:15, you add one part concentrate to fifteen parts diluent, so the final solution contains one-sixteenth concentrate. This specific dilution is chosen to deliver the intended chemical activity while staying safe for people and compatible with the equipment. Using a more concentrated mix (fewer than fifteen parts diluent) raises the strength, which can cause residue, corrosion, or irritation. Using a more dilute mix (more than fifteen parts diluent) reduces effectiveness. The 1:15 ratio is the recommended balance for these factors.
