Product review (5 stars): A must-have for console humidifiers.
Adding a few capfulls of this to the humidifier tanks every few weeks keeps the plastic clean and mold-free. I was amazed at how well it worked, restoring the white plastic to pure white, and de-hazing the clear bits. I like knowing that I can run my humidifier without it just slowly becoming a hub for mold and growth. This is so necessary, I almost wish humidifiers had a separate little reservoir to slowly drip it into the water, like how dishwashers have a reservoir for Jet Dry.
