What Is the Most Successful Product in 'Shark Tank' History? 100 Episodes

In honor of the 100th episode of "Shark Tank," the Sharks looked back the most successful product ever featured on the show.

Aaron Krause got Shark Lori Greiner to make a deal for his company "Scrub Daddy," which makes sponges. Before appearing on the show, the company had a mere $100,000 in sales. Now, it projects $25-30 million in sales in 2014.

"The night the show aired, there was 30,000 hits to our website. Instantly you have a name brand and you have to be ready and prepared when they happens," Krause told ABC News.

The Scrub Daddy sponge, which is sold om QVC among other outlets, is made of a high-tech polymer, strong enough to clean a grill.

Its texture changes with the water temperature -- hard for cold, soft for hot. Krause also told ABC News it is more sustainable and smells better than other competing brands that collect bacteria.

"This special material has also been independently lab tested to not retain odors for up to two months while being safe to use on just about every household surface," he said.

Krause has two patents on the design of the sponges but noted that "patents are not the end all, be all."Once you get a patent, you open yourself up to competition because you disclose to entire world how you make it and what it's made of."
