Remove Stains and Mold from Old Photos (AI Inpainting)
Old prints collect stains — foxing spots, cup rings, mildew blooms. Most sit on the surface or in the emulsion and can be reconstructed digitally without touching the print. The key is letting AI rebuild the missing pixels rather than just painting over them.
Types of stains AI handles well
- Foxing: small brown age spots — easy to fill.
- Cup rings / liquid marks: ring-shaped discoloration.
- Light mold: surface blooms on dried prints.
Start in scratch & stain repair, then finish with the overall fix guide.
How inpainting rebuilds
AI samples the surrounding pixels — a neighbor’s sleeve, the wall behind — and generates plausible content for the stained region. The result looks continuous, not patched. See it in OldPhoto’s restore tool.
Prevent recurrence
Cleaned digitally is only half the job. Store prints dry (see preservation guide) so mold doesn’t return to the physical print.
FAQ
Will cleaning remove original detail? If the stain covered real content, AI guesses it — usually convincingly, but not pixel-perfect.
Active mold — clean at home? No. Active mold needs containment; consult a conservator, then digitize.
