To safely clean precious film, find a clean and dust-free area to work. Ensure your hands are clean and dry before handling the film.
In order to safely clean precious film, you will need to gather cleaning supplies. Use lint-free, non-abrasive cloths like microfiber or lens cleaning tissues. You will need to take great care with these delicate materials.
Find a Clean and Dust-Free Area to Work In
Find a clean and dust-free area. Ensure your hands are clean and dry before handling the film to avoid transferring dirt and oil.
Gather your cleaning supplies. You will need lint-free, non-abrasive cloths, such as microfiber or lens cleaning tissues. Include a gentle air blower (not canned air), a soft brush, and a film cleaning solution specifically designed for classic films, such as PEC.
🛑 The following instructions involve certain risks to the original. If you don’t feel confident performing them,please consult a professional. Alternatively, digitize the film first and make any repairs you can during post-editing. Please also refer to my Disclaimer & Copyright page on this website.
Carefully inspect the film for any visible dirt
Carefully inspect the film for any visible dirt, debris, stains, sticky substances, or mold growth. If you observe significant damage or deterioration, consult a professional film archivist or conservation specialist. They can offer guidance on the best techniques for cleaning and restoring the film without causing further harm. Additionally, establish proper storage conditions to protect the film from future damage.
Remove Loose Debris: Before applying any cleaning solution, use an air blower or a soft brush with gentle bristles to remove loose debris like dust or dirt. Gently sweep the film’s surface without applying too much pressure.
Film-Safe Cleaning Solution:
Apply a film-safe cleaning solution to a lint-free cloth or lens-cleaning tissue, avoiding direct application to the film to prevent damage. Gently wipe the film in a straight, linear motion using PEC cleaning cloths or solution to remove dirt or marks. Avoid areas with fungus or aggressive deposits; seek professional help for these.
Spot Cleaning:
For stubborn stains or sticky residues, lightly dampen a clean cloth with the cleaning solution and gently dab the affected areas. Do not saturate the film or rub too hard, as this can cause damage (refer to the earlier warning). If a blemish is too difficult to remove, digitize the film and remove it during post-editing.
Allow Air Drying:
Once cleaned, allow the film to air dry before handling or storing it. Do not use a hair dryer or any other direct heat source, as this will cause the film to shrink or warp.
Proper Storage:
Make sure you store it properly. After the film has thoroughly dried, keep it in a cool, dry environment. Avoid direct sunlight, extreme temperatures, and excessive humidity.
A supply of 50 acid-free archival film sleeves can help protect the film. An acid-free negative sheet folder also aids in preventing further deterioration.
It is important to note that to safely clean film, you should proceed cautiously and use only appropriate techniques. If you are unsure, seek the support of an expert restorer with experience working with classic film.
Quick Reference: The “Safe Film” Cheat Sheet
| Task | Archival Best Practice |
| Storage Temp | Below 18°C (65°F) for Black & White; Below 4°C (40°F) for Color. |
| Humidity | Maintain between 30% and 50% RH. Avoid basements and attics. |
| Cleaning | Use a HEPA vacuum for loose dust; 99% IPA for stubborn spots. |
| Handling | Use Nitrile gloves; handle only by the edges of the film. |

1. The National Film Preservation Foundation (NFPF)
The Film Preservation Guide: The Basics for Archives, Libraries, and Museums
The NFPF’s guide is widely considered the “gold standard” for anyone starting a preservation project. It was written specifically for non-specialists to provide practical, low-cost solutions for managing film collections.
- Best For: Understanding the full lifecycle of film care, from identifying film types (Nitrate vs. Safety) to long-term storage strategies.
- Key Insight: It emphasizes that storage is the most effective preservation tool. If you can control the temperature and humidity, you can slow chemical decay by decades.

2. Library of Congress (LOC)
Care, Handling, and Storage of Motion Picture Film
As the primary conservator of American film heritage, the Library of Congress provides the most scientifically grounded “Do’s and Don’ts” for handling precious originals.
- Best For: Precise handling protocols and environmental specifications.
- Key Insight: The LOC highlights the “Silent Killers”: fingerprints and dust. They recommend using nitrile gloves instead of cotton (which can be abrasive) and handling film strictly by its edges to avoid transferring oils to the emulsion (Library of Congress, n.d.).
