What Rozone does

Rozone Limited is a UK-headquartered industrial cleaning products company that designs, formulates, and manufactures bioremediation-based parts washing systems and chemical cleaning solutions from its operational headquarters in Darlaston, West Midlands. The company's core technology is a self-recycling parts washer (the ROwasher, available in Static, Mobile, XL, and Benchtop configurations) that uses naturally occurring oil-eating micro-organisms delivered through a Microbial Filter Mat to break down oil and grease into carbon dioxide and water. This is paired with pH-neutral, non-toxic, non-flammable ROwash degreasing solutions (ROwash 03 General, ROwash 06 Specialist Metals, and ROwash Bike) heated to 42°C, eliminating hazardous waste streams and the need for service contracts that competitors typically require.

The company serves seven primary verticals — automotive fleet workshops, bike workshops, commercial kitchens, damage restoration, defence, industrial engineering, and plant hire — with notable customers spanning an F1 team, TAIT Towers, PANDECT Precision Components, Polygon, and Cambridge Fire & Rescue. Over 26,000 parts washers have been placed since 1996, and the technology holds ISO 9001, ISO 14001, NSF, and aerospace-grade certifications (Boeing BSS7432B, AMS1526C, Douglas CSD#1, Airbus AIMS09-00-002), with Romess brake and clutch bleeding equipment carrying approvals from Mercedes, BMW, Ford, Volvo, and Renault.

Rozone's revenue model combines one-time hardware sales (parts washers, Hotwasher aqueous spray systems, Romess service equipment), a recurring consumables annuity from monthly Microbial Filter Mat replacement and 18-month fluid changes, plus broader industrial and damage restoration chemicals distributed under the Duct-Tech brand. Distribution is primarily direct through the company website and an inside sales team, supplemented by industry trade shows. The company is privately held with no institutional investors identified, originated as part of the historic Rubery Owen Group, and is led by Managing Director Cliftin Bower. International expansion is underway through a new Rozone GmbH facility in Frankfurt, a dedicated ROwasher export brand (rowasher.com), and a dedicated export manager appointed in 2025.

Scale indicators7 records

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Zep Inc. Zep is a large-scale manufacturer of industrial and institutional cleaning chemicals, including degreasers and specialty cleaners, sold through distribution. It serves the same automotive, fleet, and facility maintenance customers as Rozone but at much greater commercial scale and broader SKU depth.
• Kärcher: Kärcher is a global leader in cleaning equipment, including industrial pressure washers and parts cleaning systems. Its commercial cleaning portfolio competes with Rozone in fleet and industrial cleaning applications, though Kärcher is more equipment-focused than chemistry-focused.
• Safety-Kleen: Safety-Kleen is the dominant North American provider of industrial parts washing and hazardous waste management. It offers both solvent and aqueous parts washers across automotive and industrial end markets directly comparable to Rozone, but at vastly greater scale and with a service-contract-driven model that Rozone's no-contract positioning explicitly differentiates against.
• CRC Industries: CRC Industries is a major specialty chemicals manufacturer producing degreasers, cleaners, and lubricants for automotive, industrial, and MRO markets. Its product lines overlap with Rozone's vehicle, workshop, and industrial cleaning chemicals, providing comparable B2B chemistries.

Direct peers

• Kleen-Rite Corporation: Kleen-Rite is a US-based manufacturer and distributor of parts washers, pressure washers, and industrial cleaning equipment serving automotive and industrial workshops. Its parts washer product line competes in the same SME workshop segment as Rozone's ROwasher static and mobile units.
• Cuda Cleaning Systems: Cuda manufactures aqueous-based parts washers and industrial cleaning systems for automotive, aerospace, and industrial customers. While Cuda uses heated aqueous (not bioremediation), the product category, target verticals, and B2B sales motion closely mirror Rozone's ROwasher and Hotwasher lines.
• Smartwasher (Better Engineering): Better Engineering's Smartwasher is the original US-market bioremediating parts washer that Rozone imported to the UK in 1996. Both sell self-recycling parts washers using oil-eating microbes with monthly filter mat and long-life fluid consumables. Rozone even services Smartwasher units in the UK, evidencing direct product and technology parity.

Emerging players

• Simple Green: Simple Green produces non-toxic, biodegradable industrial and consumer cleaning chemicals used in workshops, fleet, and facility maintenance. Its chemistry competes with Rozone's ROwash degreasing solutions across overlapping use cases, though Simple Green lacks the integrated parts washer hardware ecosystem.
• Chem-Trend: Chem-Trend manufactures specialty release agents, cleaners, and process chemicals for moulding, casting, and industrial cleaning applications. Its industrial cleaning chemistry overlaps with Rozone's ROwash offerings in metalworking and precision component cleaning verticals (e.g., aerospace, engineering).
• Nilfisk: Nilfisk manufactures professional cleaning equipment and detergent solutions for industrial and commercial customers. Its parts washer and industrial degreasing equipment lines overlap with Rozone's Hotwasher and ROwasher product categories across automotive and industrial workshops.
