Costco Bets Big on Green Cleaning With Nationwide Laundry Sheet Launch

NEW YORK, NY – January 28, 2026 – The bulky, plastic laundry detergent jug, a staple of American households for decades, is facing its most significant challenge yet. Clean Cult, a brand founded on the mission to eliminate plastic from cleaning routines, has partnered with retail giant Costco to launch its Fresh Linen Laundry Detergent Sheets nationwide. The move marks the first time a laundry sheet product has been rolled out across all U.S. Costco regions and on Costco.com, making a once-niche sustainable product accessible to millions of mainstream consumers.

This launch represents a pivotal moment for both the cleaning industry and conscious consumerism. By introducing a supersized, 180-sheet value pack, Clean Cult and Costco are making a bold statement: sustainability can be affordable, effective, and convenient for the average family. The product, which has already earned accolades from publications like Good Housekeeping and Women's Health, is poised to disrupt a category long dominated by heavy liquids and pods.

The Sheet Revolution Hits the Mainstream

The laundry aisle is undergoing a quiet but powerful transformation. Consumers, increasingly wary of single-use plastics and seeking simpler solutions, are driving demand for alternatives. Laundry detergent sheets—concentrated, pre-measured, dissolvable strips of detergent—offer a compelling answer. They eliminate the mess of liquid spills, the bulk of heavy jugs, and the environmental burden of plastic packaging.

Clean Cult's offering at Costco is designed for mass adoption. The club-exclusive 180-sheet pack, priced at $22.99, brings the cost per load to a highly competitive level, directly challenging the economic proposition of traditional detergents. This strategic pricing is key to moving laundry sheets from an eco-luxury item to an everyday staple.

"As a company founded to remove plastic from the household cleaning category, this moment signals our mission going mainstream," said Ryan Lupberger, CEO of Clean Cult, in a statement. "Seeing laundry detergent sheets reach nationwide scale at Costco marks a real shift in how people want to clean — simpler, smarter, and with less waste. We're proud to help lead that change while delivering great performance at a great value."

This launch is not Clean Cult's first foray into the club store. It follows a successful introduction of the brand's All-Purpose Cleaner Variety Pack at Costco in April 2025, indicating a strong and growing partnership built on shared goals of value and waste reduction.

A Growing Market for Plastic-Free Laundry

The timing for this nationwide rollout could not be better. The market for laundry detergent sheets is experiencing explosive growth. Independent market research aligns with industry projections that forecast the segment could reach $2.5 billion in annual sales by 2030. While a fraction of the gargantuan global laundry care market—valued at over $100 billion—this growth trajectory suggests laundry sheets could capture as much as 5% of the entire market within the next decade.

The appeal is rooted in profound logistical and environmental advantages. A single paper-thin box of 180 sheets weighs a fraction of the equivalent liquid detergent, drastically reducing shipping weight, fuel consumption, and carbon emissions throughout the supply chain. For consumers, it means freeing up valuable shelf space and eliminating the environmental guilt associated with discarding another massive plastic container.

Clean Cult, founded in 2019, has been at the forefront of this movement. The company was the first to package soaps and detergents in patented, 100% recyclable paper-based cartons. This commitment to plastic reduction is further validated by its 'Certified Plastic Neutral' status through rePurpose Global, a certification that ensures for every bit of plastic the company uses, an equivalent amount is removed from the environment. The company's participation in the U.S. Plastic Pact and its use of How2Recycle labels further cement its role as a leader in sustainable packaging and corporate responsibility.

Value Meets Sustainability on Aisle Five

Costco's decision to go nationwide with Clean Cult is a calculated move that reflects the retailer's evolving sustainability strategy. Known for its bulk purchasing model that inherently reduces packaging waste per unit, Costco is increasingly leveraging its immense market power to promote eco-friendly products that also meet its members' high standards for value.

The pricing of Clean Cult's sheets is a critical component of this strategy. At approximately $0.128 per load, the Costco offering significantly undercuts many of the leading direct-to-consumer laundry sheet brands, whose prices often range from $0.20 to over $0.30 per load. This aggressive pricing makes the sustainable choice the economical choice, removing a key barrier to widespread consumer adoption.

This partnership exemplifies the "Costco Effect"—the ability of a mass retailer to take a promising product and scale it to a level that fundamentally alters a market. By providing a national platform, Costco is not just selling a product; it's validating a new category and accelerating the shift away from wasteful, legacy formats.

Performance and Promises Under Scrutiny

For any new detergent format, the ultimate test is in the wash. Early adopters of laundry sheets have sometimes questioned whether the minimalist strips can tackle tough stains as effectively as their liquid counterparts. Clean Cult addresses this head-on, citing independent testing from Sterling Research Laboratories. The results reportedly show that the sheets perform as well as or even better than leading detergent brands when removing common, stubborn stains like spaghetti sauce, coffee, and makeup.

The cleaning power comes from a multi-enzyme formula designed to dissolve completely in both hot and cold water, a crucial feature for energy-conscious consumers. The formulation is also free from a list of controversial ingredients, including dyes, phosphates, SLS, 1,4-dioxane, phthalates, and parabens, making it a suitable option for households with sensitive skin or environmental concerns.

As Clean Cult's paper-based boxes begin appearing in shopping carts from coast to coast, it’s clear that the laundry aisle is undergoing a fundamental transformation. This launch is more than just a new item on the shelf; it represents a convergence of consumer demand for sustainability, corporate strategy from a retail giant, and product innovation that together are rewriting the rules for home cleaning.
