The short answer: most clothing and bedding from a mold-affected house is salvageable. Standard detergent washes around mold and mycotoxin residue rather than breaking it down, which is why fabrics can come out of the machine smelling clean and still cause a reaction. What is needed is enzymatic breakdown, hot water where the fabric allows, and thorough drying.
Why "it smells fine" is not the test
Smell tells you about mVOCs — the volatile gases active mold produces. It does not tell you about mycotoxins, which are not volatile and have no smell.
So fabric can smell perfectly clean and still carry residue. People with genuine sensitivity often report reacting to laundered clothes and being told it is in their head. It usually is not; it is that ordinary laundering is not designed for this.
What ordinary detergent does and does not do
Standard detergent is surfactant chemistry. Surfactants lift soil off fibres and hold it in suspension so it rinses away. That works well for what it was built for.
Mycotoxin residue is different. It binds to fibres, it is not a particulate that lifts, and much of it survives a normal wash. An enzyme detergent works by degrading the organic material rather than trying to float it off. That is what FabricKlear is for.
Method
- Do not shake items out indoors. Bag contaminated laundry where it is and carry it to the machine. Shaking aerosolises everything.
- Wash smaller loads than usual. Fabric needs to move freely. A packed drum is the most common reason a wash underperforms.
- Use the hottest water the fabric allows. Check labels, but hot outperforms cold here.
- Use an enzyme detergent and give it the full cycle rather than a quick wash.
- Consider a second wash for heavily affected items. It is cheaper than replacing them.
- Dry completely. Damp storage is how you start the problem again. Outdoors in sun is excellent if pollen is not an issue.
- Clean the machine afterwards. Run an empty hot cycle. Check the door gasket on a front loader — the fold traps water and grows its own colony.
Items that need different handling
Dry-clean-only. Tell the cleaner what they are dealing with. Perchloroethylene is a solvent process, not a biological one, and results vary.
Down and wool. Washable but slow to dry, and incomplete drying is worse than not washing. Give them proper drying time.
Leather and suede. Surface wipe only. Specialist work if affected.
Shoes. Fabric uppers wash. Leather and dense foam midsoles are hard to treat all the way through, and this is where disposal is often the honest answer.
Mattresses and pillows that got wet. Not salvageable. Growth is internal.
Sequencing matters
Do not wash everything and put it back into a house that is still contaminated. The order is: fix the water, remediate the structure, clean the contents, then return the laundry. Laundry done first just gets recontaminated, and then people conclude the products do not work.
The full sequence is in how to clean your home after mold remediation.
Common questions
Does washing remove mycotoxins from clothes?
Standard detergent washes around the residue rather than degrading it. An enzyme detergent breaks down the organic material, which is the mechanism that actually clears it.
Can I use hot water?
Use the hottest the fabric allows. Hot outperforms cold for this.
What about clothes that smell fine?
Smell indicates active growth, not residue. Mycotoxins have no odour, so smell is not a reliable test.
Do I need to wash clothes from other rooms?
Yes. Contaminated dust travels further than containment does, and an HVAC system distributes it throughout the house.
