Water & Fire Damage
How to document water, soot and fire exposure without making the package worse.
Water and fire exposure can damage cardboard, plastics, inks, adhesives and the contents inside a still-sealed package. The first job is not cosmetic restoration. It is to stop ongoing damage, protect people, and create a record of what happened before anything is cleaned, flattened, dried or discarded.
Stabilize before you clean
Move the item away from active water, heat, smoke and unstable debris. If the package is wet, support it from underneath rather than gripping softened corners. If there are signs of contaminated water, active mold, melted plastic, leaking batteries or chemical residue, treat that as a safety problem first.
Photograph it exactly as found
Take wide photographs showing where the item was stored, then front, back, all sides, seams, labels, barcodes and close-ups of affected areas. Record tide lines, soot patterns, blister clouding, warped cardboard, softened glue, staining and any places where shrink or tape has lifted.
Do not force wet cardboard flat
Paperboard and printed stock can delaminate, stretch and set into new shapes while wet. Heavy pressing can transfer inks, emboss textured surfaces or crush internal structures. Support the object and avoid “fixing” a warp before you understand the material.
Treat soot as more than dust
Dry-looking soot can be oily or abrasive. Wiping it can grind particles into coatings or spread residue. Household cleaners, alcohol, solvents and wet wipes can also change inks, gloss coatings, stickers and adhesives.
Separate damage from tamper evidence
A package can remain unopened and still be badly compromised. Water may loosen old tape or labels without anyone tampering with the item. Heat can shrink or distort plastic. Record the change as condition evidence instead of automatically calling it resealing.
Watch for hidden contents risk
Electronics, toys with installed batteries, metal components and paper inserts can deteriorate inside an apparently intact package. Bulging, rust staining, crystalline residue, strong chemical odor or discoloration near battery areas are reasons to isolate the item and consider specialist handling.
Field checklist
- Stop active exposure and isolate hazards
- Photograph the item and storage context
- Record water lines, soot, warping, odors and adhesive changes
- Do not peel stickers, tape or shrink wrap
- Do not use household cleaners or solvents
- Export a Case File before treatment
- Consult a conservator or category specialist when value or risk justifies it
FAQ
Should I use a hair dryer on wet packaging?
Avoid concentrated heat. It can warp plastics, set stains, distort shrink wrap and accelerate adhesive changes.
Does an intact seal mean the contents are safe?
No. Moisture, heat, corrosion and battery leakage can damage contents without visibly breaking the outer seal.
Should damage be hidden before resale?
No. Condition problems and any treatment should be described clearly. Documentation is more useful than cosmetic concealment.
