Product review (5 stars): Effective for preventive maintenance of DEhumidifiers too
I ordered Sunbeam Humidifier Bacteriostat Solution for a Whynter 30-pint dehumidifier that operates 24/7 during the humid summer in North Carolina.  Im using the collected water for grass seedlings and don't want to add anything caustic to the tank.  I chose the Sunbeam solution because it uses an effective chemical (same ingredient as Clorox) but is more dilute than other bacteriostat solution brands.  I put a little less than 2 capfuls into an empty Wynter 7-pint tank once a week, throw that water down the drain after the tank fills, then use subsequent tanks for the grass seedlings without any problems.  Mold is much easier to prevent than to clean up later, and the Sunbeam solution is doing a good job.
