The art and science of film preservation play a crucial role in protecting cultural memory. Whether restoring classic motion pictures or maintaining rare archival footage, professionals rely on precise, non-damaging methods to keep film intact. One of the most important steps in that process is film cleaning—a step historically dominated by 3M™ Novec™ 8200.
But with the discontinuation of Novec™ 8200, preservationists have faced a major challenge: how to replace a trusted solvent without compromising safety, performance, or the integrity of their collections. That’s where BestSolv® 7200 comes in—a scientifically engineered solution that offers a seamless drop-in replacement for Novec™, purpose-built for preserving film and protecting the future of motion picture archives.
Media Migration Technology (formerly Lipsner Smith) has tested BestSolv® 7200 and confirmed it as a highly effective replacement for 3M™ Novec™ 8200 in their film cleaning equipment, which has been trusted in the industry for over 25 years.
Why Film Cleaning Is Essential to Movie Preservation
Film cleaning is the critical first step before scanning, archiving, or restoring film. Contaminants like dust, oil, and mold can cause physical damage or compromise image quality. In movie preservation, where many reels are the only copies in existence, cleaning must be thorough yet non-destructive.
Professionals in preservation settings use specialized solvents and equipment to gently remove surface contaminants while maintaining the integrity of the film base and emulsion. This is especially important for preserving film negatives, which often serve as the master source for future reproductions or digital transfers. Without careful cleaning, even well-preserved negatives can suffer irreversible damage during handling or processing.
Solvents must not harm delicate emulsions or leach plasticizers from film bases such as acetate and Estar™ film. That’s why the industry depended on Novec™ 8200—and why replacing it required more than a “similar” product.
The End of Novec™ 8200 and the Need for Safe Alternatives
3M™ Novec™ 8200 was widely adopted for its unique combination of performance and safety: non-toxic, non-flammable, zero ozone depletion potential (ODP), and excellent compatibility with acetate and Estar™ film substrates. It was approved for use in the Lipsner-Smith CF-8200, Lipsner-Smith CF-9200 and other retrofitted Lipsner-Smith high-speed film cleaning machines, delivering consistent results without harming delicate film.
When 3M™ Novec™ was discontinued, facilities were left scrambling. Alternatives like perchloroethylene (Perc) are still used in some contexts, but their toxicity has led to increasing regulatory scrutiny and restrictions. Worse, unknown or untested solvents could introduce residue or cause subtle damage that only appears years later—an unacceptable risk in archival film cleaning.
With so much at stake, finding a chemically stable, residue-free, and compliant replacement wasn’t just a preference—it was a necessity.
Introducing BestSolv® 7200: A Trusted Film Cleaning Fluid
Recognizing the urgency, the team at Best Technology analyzed Novec™ 8200 using advanced techniques like gas chromatography-mass spectrometry (GC-MS) and Nuclear Magnetic Resonance (NMR). Our objective was clear: develop an exact match, not just a similar product.
