I just had a heart attack. My Nasonex (allergy nasal spray) just leaked on the bottom of my black denim neo cabby. I blotted the excess and the microfiber appears to be (quickly) drying without a stain. That doesn't surprise me -- I've dripped Nasonex on my clothing and haven't had a stain. Better still, nothing seeped through to the denim. Whew. Time to store that sucker in a Ziploc and hope allergy season ends already.
