Here’s the science! When the Bathroom Assistant passes an electrical charge through the salt (NaCl) solution, the sodium separates from the chloride. Chloride is negatively charged and is attracted to the positive side of the electrical charge where it bonds with oxygen and hydrogen from the water. It gets converted from Cl- to HOCl, otherwise known as hypochlorous acid, the active ingredient in the Bathroom Assistant’s cleaning spray.
Hypochlorous acid is so gentle and effective it’s commonly used in wound healing products. The sodium is positive and is thus attracted to the negative charge, where it also bonds with oxygen and hydrogen and is electrochemically converted to sodium hydroxide or NaOH. The vinegar is the key to getting the right pH. Without the right pH, you could get a solution that is mostly bleach (sodium hypochlorite). When you lower the pH to exactly the right level, the hypochlorite converts to hypochlorous acid. It’s the hypochlorous acid that makes the solution so gentle compared to cleaning with bleach.
Over time, the electrolyzed water dissipates back to a natural saline solution, making cleaning the toilet safe for your pets, kids, plumbing, and the environment.
