Contents: What to Clean, What to Keep, What to Let Go
The hardest decisions in a mold project are not about drywall — they are about belongings. This guide provides a rational framework for triaging contents by material, exposure, and replaceability, and for avoiding recontamination of a cleaned home.
The three-bucket triage
Sort everything by material: non-porous (glass, metal, hard plastic, sealed wood) can almost always be cleaned and kept; semi-porous (finished wood furniture, some leather) can often be cleaned with effort and verified; porous (upholstery, mattresses, carpets, stuffed textiles, paper, particleboard) holds contamination in its structure and usually cannot be reliably restored once directly contaminated.
Proximity and duration modify the buckets: porous items far from the source in a short-duration event fare better than anything stored in the contaminated room for years.
Cleaning that actually works
Non-porous items: HEPA vacuum and damp-wipe, exactly like the building. Textiles that can be laundered: wash thoroughly, ideally multiple cycles. Semi-porous furniture: HEPA vacuuming of every surface and crevice, damp-wiping of finished surfaces, and honest assessment of joints and unfinished undersides where particles lodge.
Items cleaned inside a still-contaminated house are not clean. Contents work happens in a controlled space, and cleaned items stage somewhere the building cannot recontaminate them.
The sensitive-occupant standard
For highly sensitized individuals, some practitioners advise stricter contents decisions than building science alone would demand — particularly for items with sentimental daily contact like bedding, pillows, and favorite chairs. The rational compromise: apply strict standards to the bedroom and soft items with hours of daily contact, and standard cleaning protocols to hard goods.
Papers, photos, and irreplaceables
Irreplaceable paper and photographs can be triaged: digitize everything, keep originals only for items that justify professional document cleaning, and store keepers in sealed containers outside living space until the household is stable. Sentimental value is real value — the goal is preserving what matters without preserving the exposure.
Moving without bringing it with you
Households relocating from a contaminated building should clean contents on the way out, not after arrival. Non-porous goods get cleaned and packed in new boxes; used boxes from the old house are a classic recontamination vector. Porous items from heavily contaminated spaces deserve a hard conversation before they get a moving-truck seat.
Common questions
Do I really have to throw everything away?
Almost never. Blanket 'discard everything' advice is as lazy as 'keep everything.' Material-based triage keeps most hard goods and launderable textiles while focusing losses on porous items with direct or long-duration contamination.
Can electronics be saved?
Usually. Electronics are largely non-porous but their fans and vents collect dust. HEPA vacuuming of vents and exterior cleaning handles most cases; heavily exposed items with internal dust loads can be professionally cleaned or replaced based on value.
What about clothes?
Launderable clothing is among the easiest categories: thorough washing removes particulate contamination. Dry-clean-only items can be professionally cleaned. The exception is clothing stored in direct contact with growth, which deserves item-by-item judgment.
