What to Throw Away After a Flood (and What to Keep)

One of the hardest decisions after a flood is figuring out what stays and what goes. Floodwater is not clean water — it carries sewage, chemicals, pesticides, and bacteria that saturate porous materials beyond recovery. The general rule: if it absorbed floodwater and you cannot fully clean and dry it within 24–48 hours, throw it away. This guide breaks down every major category of household items so you can make smart decisions quickly — before mold starts growing.

Before You Touch Anything: Document First

Your insurance claim depends on evidence. Before removing a single item from your flooded home:

Take photos and video of every room — walls, floors, furniture, appliances, personal items. Shoot wide angles and close-ups.
Make a written inventory of damaged items with approximate values and purchase dates.
Keep samples of damaged materials — a small piece of carpet, a section of drywall — as physical evidence for your adjuster.
Do not discard anything until your insurance company authorizes removal, unless the item poses an immediate health risk. Call your agent before starting cleanup.

Items You Must Throw Away

These items cannot be safely decontaminated after floodwater exposure. Discard all of them:

Food and Beverages

All food touched by floodwater — including sealed containers with screw-top or snap-on lids (floodwater seeps past these seals)
Canned goods with dents, rust, or swelling — undamaged, factory-sealed cans can be cleaned with a bleach solution and relabeled
Everything in the refrigerator/freezer if power was out for more than 4 hours (fridge) or 48 hours (full freezer)
All medications that contacted floodwater — they cannot be decontaminated

Porous Materials and Soft Goods

Mattresses and box springs — even partial saturation cannot be reversed
Pillows, stuffed toys, and upholstered items that absorbed floodwater
Carpet and carpet padding — padding is always discarded; carpet may be salvageable only if flooded with clean water (not sewage) and dried within 48 hours
Particleboard and MDF furniture — these materials swell, crumble, and harbor bacteria once saturated
Books, papers, and documents that cannot be air-dried or freeze-dried within 48 hours

Building Materials

Drywall — cut at least 12 inches above the visible waterline (moisture wicks upward). See our drywall repair guide.
Fiberglass and cellulose insulation — saturated insulation loses its R-value and becomes a mold incubator
Laminate and engineered flooring — these materials trap moisture between layers and cannot be dried in place
Vinyl flooring — must be removed because moisture and silt collect underneath, promoting mold growth

Personal and Household Items

Cosmetics, toiletries, and personal hygiene items
Stuffed animals and fabric toys
Anything made of pressed wood or particleboard (bookshelves, entertainment centers, most flat-pack furniture)
Cleaning supplies and chemicals — containers may have leaked into floodwater or been contaminated

Items You Can Usually Keep (With Proper Cleaning)

Non-porous materials that did not absorb floodwater can typically be cleaned, disinfected, and saved:

Hard-Surface Furniture

Solid wood furniture — if dried within 48 hours, solid wood can usually be salvaged. Clean with a disinfectant solution, remove drawers and doors for airflow, and dry slowly to prevent warping. See our furniture cleaning guide.
Metal furniture — clean, disinfect, and dry thoroughly. Treat any rust spots promptly.
Plastic and resin furniture — wash with a bleach solution (1 cup bleach per 5 gallons water), rinse, and air dry.

Appliances

Large appliances (washer, dryer, refrigerator, stove) — do not power on until inspected by a qualified technician. Many can be professionally serviced and restored. Gas appliances require a licensed plumber or gas technician before reconnection.
Small appliances — generally not worth the cost of professional inspection. Replace microwaves, toasters, coffee makers, and similar items.

Hard-Surface Flooring

Ceramic and porcelain tile — tile itself is non-porous. The concern is moisture trapped underneath and in grout lines. Remove baseboards, clean tile surfaces with disinfectant, and ensure the subfloor dries completely before resealing. See our flood-damaged flooring guide.
Concrete floors — clean and disinfect the surface. Monitor for moisture wicking from below. A dehumidifier may need to run for several weeks.
Solid hardwood — may be salvageable with professional drying if caught early. See our hardwood floor restoration guide.

Documents and Valuables

Important documents (birth certificates, titles, tax records) — if still intact, freeze them in a plastic bag to halt mold growth, then air-dry or freeze-dry later. Many professional document restoration companies can recover water-damaged paper.
Photographs — gently rinse in clean water, lay flat to air-dry face-up on a clean surface. Do not stack or touch the image surface.
Jewelry and coins — clean with mild soap and water, dry completely.

The 48-Hour Rule

The most critical factor in save-vs-discard decisions is time. Mold begins colonizing within 24–48 hours on any damp organic surface. If you cannot clean and fully dry an item within that window, the odds of salvaging it safely drop dramatically.

Material	Can Dry in 48 Hours?	Verdict
Solid wood (small items)	Maybe, with airflow + dehumidifier	Try to save — monitor for mold
Particleboard / MDF	No — absorbs deeply, swells	Always discard
Carpet	Only if clean water + professional extraction	Discard if sewage-contaminated
Carpet padding	No	Always discard
Drywall	No — wicks moisture, crumbles	Cut out and replace
Mattress / upholstered furniture	No	Always discard
Metal / glass / hard plastic	Yes	Clean, disinfect, keep
Clothing	Yes, if machine-washed in hot water	Launder and keep

Clothing and Fabric

Most washable clothing can be saved if laundered properly:

Pre-rinse in clean water to remove mud and debris
Wash in the hottest water safe for the fabric with detergent and 1/2 cup of chlorine bleach (for whites) or color-safe bleach
Run through two full wash cycles
Dry in sunlight when possible — UV light provides additional disinfection

Discard: Leather goods, suede, and items that cannot tolerate hot water if they contacted sewage-laden floodwater. Shoes that absorbed floodwater are generally not salvageable unless they are rubber or waterproof boots.

Electronics

Electronics submerged in floodwater are usually total losses, but some can be recovered:

Do not attempt to power on any device that was submerged — this can cause short circuits and permanent damage
Computers and phones: A data recovery specialist may be able to retrieve data from hard drives and memory cards even from water-damaged devices
TVs, stereos, game consoles: Generally not worth the repair cost. Replace and file with insurance.
HVAC systems: Must be inspected by a licensed HVAC technician. The ductwork may need cleaning or replacement to prevent distributing mold spores.

How to Handle Hazardous Materials

Floodwater often mixes with household chemicals, creating additional hazards:

Propane tanks: Close the valve, secure upright, and have a professional inspect before reconnecting
Paint, pesticides, pool chemicals: If containers leaked or were compromised, contact your local hazardous waste disposal facility. Do not put these in regular trash.
Asbestos-containing materials: Older homes may have asbestos in insulation, floor tiles, or siding. If you suspect asbestos, do not disturb it — call a licensed abatement professional

Disposal Tips

Check with your municipality about special flood debris pickup schedules — many areas provide temporary dumpsters or extended collection after flooding events
Separate materials: Keep appliances, electronics, and hazardous waste separate from general debris
Photograph everything before disposal — your insurance adjuster may request evidence of discarded items
Keep receipts for replacement items — these support your insurance claim valuation

Frequently Asked Questions

Can I keep food that was in sealed cans after a flood?

Commercially sealed, undamaged cans (no dents, bulging, or rust) can be kept if you remove the label, wash the can in a solution of 1 tablespoon bleach per gallon of clean water, and re-label with a permanent marker. Discard any can with damage to the seal. Food in glass jars with screw-top lids, plastic containers, or cardboard boxes must be thrown away — floodwater penetrates those seals.

Is flood-damaged furniture always ruined?

No. Solid wood, metal, and hard plastic furniture can often be salvaged with proper cleaning and drying. The key is whether the item can be fully dried within 48 hours and whether it contacted Category 3 (sewage-contaminated) water. Particleboard, MDF, upholstered, and stuffed items that absorbed floodwater should always be discarded.

How do I know if floodwater was contaminated with sewage?

Assume all floodwater is contaminated unless you know for certain it was clean water (e.g., a burst supply pipe). River flooding, storm surge, and any standing water that mingled with stormwater systems is classified as Category 3 (black water) by the IICRC — meaning it contains sewage, chemicals, and biological hazards that require the strictest discard standards.

Should I wait for my insurance adjuster before throwing things away?

Contact your insurance company as soon as possible. Most insurers understand that health hazards require prompt removal. Document everything with photos, video, and a written inventory before discarding. Keep samples of damaged materials (a swatch of carpet, a section of drywall) for the adjuster. If health risks are immediate — visible mold, sewage contamination, structural hazard — proceed with removal and document as you go.
