DetraPel is a non-toxic, super hydrophobic spray that repels stains. The young inventor of DetraPel, Babson College student David Zamarin from Philadelphia, Pennsylvania, is pitching his business on Shark Tank on January 7. For the presentation, Zamarin has a handsome male model dip a pair of dirty shoes (he uses ketchup, mustard, and syrup to soil them first) into a tub of DetraPel. And yes, the tennis shoes are returned to a bright white. But it looks like potential investor Barbara Corcoran is more interested in Zamarin, when she gets a hold of his bright white shirt. Guest shark Rohan Oza participates in the DetraPel demonstration too, when he pours a glass of red wine on a light colored pillow.
Not only is Zamarin a great example of young entrepreneurship but he also has Shark Tank pedigree. On Facebook he identifies himself as “a former business development intern at Scholly.” Scholly is the scholarship app that received an investment from Lori Greiner and Daymond John on Shark Tank in 2015. P.S. Zamarin will graduate from Babson in 2020. New episodes of Shark Tank (Season 9) air Sundays at 9pm and 10pm on ABC. [Related: 27 Favorite Shark Tank Products — New List]
