I bought three of these items to get rid of the smell of 100 uniforms that can only be dry cleaned once a year. And given the terrible heat we've had this year, I'm not sure 3 gallons of this stuff will be enough to get us through the camping season. But that's the only reason I can get through the hiking season because, let me tell you, this form can be quite mature in mild conditions. It really deodorizes those winter wool uniforms (Southern California - what were they thinking?!) . This also comes from a person with an over-the-top sense of smell. Without Febrez's magical power to eliminate stinks, I don't think I would have survived this hiking season.
