Most Americans do not think about rust until it is too late — until the dishwasher rack is flaking, the flatware is stained, and the repair bill has already arrived. By that point, the damage is done, and the spending has begun.
More than 85 percent of American homes run on hard water. The nation’s pipes, averaging between 45 and 78 years old, are breaking at a rate of 240,000 times a year. Dishwasher rust, it turns out, is not a niche inconvenience. It is a household epidemic that costs American families hundreds of dollars in replacement racks, ruined flatware, and service calls — all to solve a problem that a simple, affordable product could have stopped before it started.
Patrick Mester, co-founder of Rust Guard, is betting that prevention is a more compelling pitch than damage control. His company has built a product squarely around that proposition — reasonable, unglamorous, and quietly necessary for tens of millions of households who have never once considered protecting their dishwasher until the rust appears.
We sat down with Mester to understand what it takes to sell Americans on something they did not know they needed.
You’re entering the U.S. market at a time when global trade tensions and supply chain uncertainties are reshaping how companies expand. What lessons from your growth in the U.K. are most relevant now, and what has surprised you about the U.S. market so far?
The U.K. taught us that scientific credibility travels. Consumers in every market want proof, not promises — and our Fraunhofer Institute validation has opened doors faster than any marketing campaign. What surprised us about the U.S. is the scale of the underlying problem.
The home improvement space in the U.S. is highly saturated. What gap are you aiming to fill, and what is your go-to-market strategy to position Rust Guard to stand out in a crowded field?
We analyzed the support pages of 17 major dishwasher manufacturers — from Miele to GE to Samsung. Every single one acknowledges the rust problem. Not one offers a preventive solution. They tell customers to buy new racks, replace flatware, or accept the problem. That gap is where Rust Guard lives.
Our go-to-market strategy is built on three pillars: retail shelf placement in the dishwasher care aisle where the category literally doesn’t exist yet, a TikTok-first creator strategy targeting home and kitchen audiences in hard water states, and scientific credibility that no competitor can match. We’re not competing for shelf space in an existing category — we’re creating the category.
With large retailers playing a critical role in consumer adoption, what is your timeline and strategy for entering major home improvement chains across the country?
We’re actively in conversations with major U.S. home improvement retailers right now. Our retail strategy is straightforward: we’re not asking buyers to take a risk on an unproven product. We come with a patented technology, a certified scientific study from the Fraunhofer Institute, TSCA compliance certification from Intertek, over 10 million units sold globally and growing consumer demand visible through social media and search.
The pitch is simple — put a patented product in your dishwasher care aisle that prevents the most common dishwasher complaint your customers have. No preventive product exists there today. Our target is to have placement confirmed with our first major U.S. retail partner within 2026.
As appliance manufacturers place greater emphasis on durability and product lifespan, are you exploring partnerships with companies like LG, Bosch, or Samsung to build on the strong consumer trust they already command?
This is something we’re very open to and genuinely excited about. Conversations with major appliance manufacturers are exactly the kind of partnerships we see as a natural next step. The logic is compelling for both sides: manufacturers spend significant resources on warranty claims and customer service related to rust damage.
A patented, independently validated product that provably reduces corrosion is a differentiation tool for them, not just a third-party accessory. Including Rust Guard as a bundled accessory or co-marketing it with new appliances turns a reactive warranty cost into a proactive customer loyalty tool. We’d welcome those conversations — and the Fraunhofer data makes them credible from the very first meeting.
Manufacturing origin has become a key issue in today’s geopolitical climate. Where is Rust Guard currently produced, and how are you planning for potential disruptions tied to tariffs, trade restrictions, or shifting supply chains?
Rust Guard is currently manufactured in China. We’re clear-eyed about the geopolitical landscape, and we’re actively building inventory buffers and logistics infrastructure through our U.S. entity, Rokitta LP, to reduce exposure to supply chain disruptions. Long-term, our goal is to produce in the United States — that’s not just a supply chain decision, it’s a strategic one. Domestic production strengthens our retail story, reduces tariff risk and positions Rust Guard as a genuinely American product for the American market.
Finally, as consumers become more cost-conscious in an uncertain economy, how do you make the case that prevention-based products are not just an added expense, but a necessary investment?
The math is straightforward, and we let it speak. A replacement dishwasher rack costs $100 to $400. New flatware — purchased two or three times because it keeps rusting — runs $50 to $300 each time. Service calls and repairs add more. The average household fighting a dishwasher rust problem spends hundreds of dollars reacting to something a $19.99 product could have prevented. Rust Guard isn’t a luxury purchase — it’s the cheapest item in that entire chain.
In an uncertain economy, prevention-based thinking wins because reactive spending is unpredictable. Rust Guard is a one-time decision that eliminates a recurring problem. That’s not a hard sell when you lay out the numbers.
