Lint Roller = Deodorant Streak Remover
Even if I'm extremely careful, sometimes I happen to get deodorant streaks on my black shirt or dress. There are plenty of tips out there to get rid of those pesky white deodorant streaks, such as using some sort of water/liquid or rubbing it with panty hose. But do you really want to get a wet spot on your shirt before you go out? What if you don't have any hosiery? One thing I know everyone has (or should!!) is a lint roller. Simply roll it over the white marks several times until they're gone. The stickiness of the adhesive should grab the white particles and remove them from your clothing. Works for me every time!(To prevent all of this from happening in the first place, don't use solid deodorant/antiperspirant.)
