How Aaron Krause turned a shelved hand scrubber into Scrub Daddy

Executive overview

Aaron Krause built a buffing-pad manufacturing business, sold it to 3M just before the 2008 financial crisis, and kept the one product nobody wanted: a hand scrubber called Scrub Daddy. Years later, washing lawn furniture in warm water revealed that the foam changed texture with temperature — soft in hot, firm in cold — making it the ideal kitchen sponge.

The insight reframed the product entirely. Scrub Daddy went from zero retail interest to a Shark Tank appearance, a $1 million sales night on air, and eventual placement in every major US retailer.

The market doesn't find you — you have to demonstrate the product until the right amplifier arrives.

From car washing to buffing pad inventor

• Krause started washing cars in high school, turned it into a real business after college, and funded early growth with an $8,000 loan from his father at 9% interest.
• Burning a car mirror with a flat foam pad led him to design a beveled-edge pad — no equipment existed to make it, so he built custom machinery with a staircase manufacturer.
• Edge Buffing Pads reached $1–1.5M in annual sales by 1998; the scalable manufacturing model attracted 3M's acquisition interest.
• A badly structured exclusivity deal with a chemical distributor nearly killed the 3M acquisition — he renegotiated a buyout clause before talks could progress.

Selling to 3M and keeping the sponge

• When 3M valued the business on EBITDA multiples, Krause hung up mid-call; they called back and tripled the offer before a deal was reached (double-digit millions, undisclosed).
• 3M carved out five items including Scrub Daddy — which had zero sales — from the deal; Krause kept them and started Innovative Accessory Products as a separate entity.
• The deal closed September 1, 2008 — the same day 3M froze all acquisitions due to the financial crisis.
• As a consultant running 3M's operation, he learned how large corporations function — knowledge he applies now running a much larger organisation.

Rediscovering the sponge

• In 2011, Krause used old Scrub Daddy prototypes to clean lawn furniture; dunking them in hot water made them soft, cold air made them hard — a temperature-response property he had never noticed.
• In the kitchen that night, the firm texture in cold water removed burnt-on food in seconds; the round shape matched cookware; cutting a smile turned the mouth into a silverware cleaner.
• His business partner of 18 years refused to invest in relaunching it; Krause used his CEO tie-breaking authority, bought out his partner, and moved forward alone.
• He secured material exclusivity with the German foam manufacturer — the specific facility's process cannot be replicated — and began cutting sponges by hand in his existing factory.

Breaking into retail

• Cold calls to Walmart, Target, Lowe's, Home Depot, and Kroger went nowhere; a friend's five ShopRite locations gave him shelf space, but sponges sat unsold without a demo.
• Live in-store demos converted every bystander; one location went from selling two or three sponges a day to a hundred — but the model was unscalable and unprofitable at wholesale prices.
• A front-page Philadelphia Inquirer business story generated inbound calls and set the stage for QVC.
• A broker got him onto QVC; his first appearance failed (40% sell-through), but the buyer gave him a second show based on energy alone — by his fourth appearance he was directing camera angles and selling out inventory each time.

Shark Tank and national scale

• Krause applied to Shark Tank after watching it through a QVC lens — he wanted the demo airtime in front of 7–10 million viewers.
• He targeted Mark Cuban; Cuban passed ("you're the Scrub Daddy but I'm not a scrub pimp"). Lori Greiner challenged the demo live on set, confirmed it was real, and became his shark.
• The episode aired October 2012; Scrub Daddy did $1 million in sales the night it aired, with IT failover and pre-built inventory ready.
• Bed Bath & Beyond and Walmart called the next day; Lori's relationships opened buyer calls that cold outreach never could.

Building and protecting the brand

• By 2014 Krause left 3M consulting — Scrub Daddy was more lucrative and gave him control over his own destiny.
• Scrub Mommy (dual-sided, odour-free soft sponge on the reverse) now outsells Scrub Daddy by ~10% in every retailer.
• Shark Tank reruns on CNBC, follow-up episodes (15 appearances total), Instagram and TikTok (5M followers), and early investment in cleaning influencers ("clean-tok") compounded awareness year over year.
• Counterfeit products carrying Scrub Daddy's exact packaging appeared on Amazon; Krause hired a private investigator, filmed the Chinese facility undercover, and raided it with Chinese government cooperation.
• The company has nearly 500 employees worldwide; Krause holds eight patents and is developing a ninth on a toilet-scrubbing system.
• Exit strategy is open — private equity is not the target; the right home is a major CPG company (P&G, Unilever, Clorox, Henkel, 3M) or an IPO, at which point Krause would step down.
