Handle film by the edges with clean, dry hands or suitable gloves and assess condition before cleaning.

Dust can often be blown away safely; fingerprints, mould and adhered residue require more controlled methods.

A practical method

1. Work on a clean dry surface
2. Separate mouldy material
3. Inspect both sides under angled light
4. Use a gentle antistatic blower for loose dust
5. Consult a conservator or specialist for active deterioration
6. Move stable film into archival sleeves

What to avoid

• Window cleaner or household alcohol
• Paper tissues
• Compressed-air propellant
• Soaking unknown emulsions
• Forcing curled or brittle film flat
