Food and grease will stick to your drain like hook-and-loop. Pretty gross. Luckily you can clear the gunk in your drain with a Bio-Flow deodorizing strip. One tiny little stick will eliminate leftover food in your drain and tame the putrid smells coming from it. Two uses, one stick. That's what we like to call a double whammy. (It's an industry term). Smelly drain? Bio-Flow drain strips will eat away at organic matter better than the no name drain cleaner you have under your sink. Drop one strip into your drain and the slow dissolving bacteria and enzymes will start to work instantly. The gunk that's stuck inside of your drain won't stand a chance against Bio-Flow's enzymes. Grease, oil, fats, scum, food all gone in a matter of minutes. How's that for easy drain maintenance.
