After drying with a cloth, leave the slides to air dry fully for at least 15 minutes, preferably face up, to avoid any moisture accumulation.
5. Restoration Options
If your slides have mounting issues or show signs of deterioration, consider restoration options:
A. Petroleum Jelly or Archival Wax
For slides that have lost their luster or need extra protection, applying a small amount of petroleum jelly can rejuvenate the surface. Alternatively, archival-grade wax can be applied for a more museum-quality finish.
B. Professional Restoration Services
For slides of high historical value or significant damage, seeking professional help may be the safest route. Museums and specialized restorers can often provide expertise beyond basic cleaning methods.
Storing Cleaned Magic Lantern Slides
Proper storage of cleaned slides is as critical as the cleaning process itself.
1. Use Archival Quality Materials
Invest in archival quality boxes and holders specifically designed for glass slides. Acid-free materials prevent further degradation over time.
2. Ensure Proper Labeling
Label each slide and its storage location accurately. Use soft, non-abrasive markers or labels placed externally to avoid direct contact with the slide itself.
3. Environmental Control
Store your slides in a dry, dark environment, protected from extreme temperatures and humidity that can lead to deterioration.
