I have a white cat, a wardrobe that almost entirely consists of the color black, and I don’t own a lint removal tool. I mostly just… never got around to getting one. Thoroughly shaking clothes out does an OK job, but sometimes I have to pick him up and my black shirt is suddenly heather gray.
So in a pinch, I’ve discovered that a hand moistened with water does the trick just fine.
You want the palm of your hand just went enough to be damp, but not wet enough to drip: it seems like this has something to do with the surface tension of the water creating friction, therefore clinging to your skin as well as whatever else comes into contact with it. Once you’ve got your palm and fingers wet, pull your shirt (or whatever) taught, and drag the flat of your hand down the length of the fabric like you would a lint brush. Your skin will be dry after doing this a couple times, but re-moisten and repeat as necessary. Once all the hair/lint is bunched up in one spot, just pick it off.
