Product review (5 stars): MUST HAVE!! especially for Crane humidifiers!
If you have any cool mist humidifier this is a MUST HAVE!! Especially the Crane humidifiers... They are made in such a way where you cant physically get to the shaft where the steam comes out... not all parts are accessible. Well once i threw the tank in the dishwasher, it came nice and clean and i wanted to find a way to KEEP OUT the yellowish GROSS slime that kept building up in there. THIS IS THE ANSWER!!

I cant begin to speak enough good things about this stuff... the capful is tiny... you put 1 capful in per gallon of water, and VIOLA! no more FORCED cleaning of the humidifiers. Now i just routinely clean them out with some vinegar or bleach once every week or 2, not becuase i have to, but because i feel like i should lol.
