I mixed ProE-Vac at the correct dilution (one ounce in one quart tap water) and the solution turned clear! What happened?
Tap water is usually treated with chlorine in various forms by your community water treatment facility. The allowed amount can vary. If chlorine levels are unusually high in your tap water, it may cause your ProE-Vac solution to become clear upon dilution. Even if the solution is clear it is still effective and may be used as usual to clean evacuation lines. Do not add any other chemicals or coloring agents to diluted ProE-Vac.
