[Restore my photo]()1 credit per successful photo · Account required[See credit packs]() Quick answer ## The short version Do not spray, wipe, or wet a mouldy photograph. Isolate it from clean materials, avoid disturbing active growth, and get professional advice for valuable, wet, flaking, or heavily affected items. Once safe to digitise, restore a copy of the scan and keep the original capture unchanged. ## Treat mould as a safety and conservation problem first Mould can stain a photograph, weaken or lift its image layer, and spread to nearby paper. Disturbing dry-looking growth can release particles, while wiping can drive contamination across the surface and remove image material. The National Archives describes mould as a potential health hazard and advises limiting handling. For valuable or sentimental items, seek conservation advice rather than diagnosing safety from appearance. ## Do not do this - Do not spray water, bleach, alcohol, vinegar, disinfectant, or household cleaner - Do not rub the image with tissues, wipes, erasers, cotton buds, or a brush indoors - Do not heat the photograph with a hair dryer or place it in direct sun - Do not peel photographs apart or pull a photograph from glass - Do not put a contaminated print onto a shared scanner without a safe handling plan ## A safer order of work 1. Separate the affected material from clean photographs without shaking or brushing it. 2. Check whether it is wet, actively mouldy, flaking, stuck, or made by an unfamiliar historic process. 3. Contact a photograph conservator for significant, unstable, valuable, or extensive damage. 4. Once the object is dry and stable enough to digitise, capture the full front and back with minimal contact. 5. Keep the raw capture unchanged and perform stain removal only on a duplicate file. ## What digital restoration can and cannot repair A digital restoration can reduce spots, scratches, haze, uneven colour, and distracting surface patterns in the scan. Small translucent marks are easier because surrounding detail still provides evidence. Where mould has removed the image layer, the output is a reconstruction. A plausible eye, letter, or piece of clothing is not proof of what was originally there. Preserve the untouched scan beside the edited copy. ## Mould after water damage Recent wet damage needs advice specific to the photographic material. Do not treat a general scanning or stain-removal article as an emergency-salvage procedure; contact a photograph conservator before attempting treatment. If the damage is recent, use professional emergency guidance rather than an ordinary cleaning tutorial. For a stable digital copy with old stains, see [how to remove stains from a scanned photo](). ## Example: an old stain and a contaminated object are different tasks You already have a clean digital scan with mottled patches from old damage. You can test digital stain repair on that copy while retaining the master. This says nothing about whether the original object is safe to handle or whether mould remains present. If you instead discover growth on the physical print, pause ordinary capture and get appropriate conservation guidance. Appearance alone is not a reliable test of activity. A cleaner digital output does not remove contamination or stabilise the original. ## FAQs Can I wipe mould off an old photo? Do not wipe active mould or use household cleaners. Friction can remove the image layer and spread spores. Seek conservation advice, especially for valuable or extensive damage. Can AI remove mould stains from a scan? It can reduce spots, veiling, scratches, and uneven colour in a digital copy when surrounding information remains. It cannot recover exact content that mould destroyed. Should a mouldy photo go on a flatbed scanner? Only after the object is dry, stable, and safe to handle. For fragile or contaminated material, a copy stand or professional digitisation may avoid contact and scanner contamination. ## Sources Preservation and technical guidance reviewed for this article. - U.S. National Archives: [Photographs: handling, enclosures, and damaged photographs]() - U.S. National Archives: [What to Do About Mold or Insect Infestation]() ## Related - [Review a digital restoration]() - [Remove Stains from Scanned Photos]() - [Restore Water-Damaged Photos]() - [Store Old Photos Safely]() - [Editorial Policy]() ## Ready to restore your photos?
