A Story From the Field: The Bags of Clothes She Was Afraid to Open This Weekend

Nutchari has sold cotton clothing and screen-printed T-shirts from a stall at a weekend market in the Chatuchak area for more than eight years. During the week, she uses the ground floor of her townhouse on a lane near Lat Yao as a stockroom. Sacks of clothes are piled almost to the ceiling, cardboard boxes hold folded shirts, rails carry dresses, and several hundred hangers sit in bundles by the wall. Every Saturday she loads her pickup at five in the morning and drives to set up the stall.

When heavy rain fell for days in October 2026, water backed up from the drains, flooded the lane and came into the house about a hand-span deep. It stayed for three days. Nutchari managed to carry some of the top sacks upstairs, but the bottom row of sacks, the cardboard boxes on the floor and the hems of the dresses hanging low on the rail all sat in the water.

When the water receded and she opened the front door, the damp, musty smell was heavier than she had expected. It was not confined to the bottom sacks. It had crept into the clothes in bags that never touched water, because fabric absorbs odors extremely well. The bottom sacks were caked in mud, and the shirts inside had tiny black spots. The cardboard boxes had gone soft and burst. The light-colored dresses had a brown tide mark along the hem, and grey-green mold was growing along the water line on the walls.

The coming Saturday was the day her regular customers would be waiting, and it was the busy season before the cool months. But Nutchari knew that if a customer picked up a shirt, held it to her nose and smelled mildew, years of reputation could disappear in a moment. And because clothing is worn against the skin, any bacteria left behind could cause itchy rashes for the people who bought it.

This situation is playing out for many clothing sellers in Chatuchak, Lat Yao, Sena Nikhom and Chan Kasem, from shophouse boutiques and weekend market stalls to online shops that use their homes as warehouses.

Why Clothing Stock Turns Musty and Moldy So Easily

Cotton, linen and rayon are all fibers that absorb moisture readily, and they contain cellulose, which is food for mold. When clothes are packed tightly into sacks or boxes in a closed, humid room, mold can grow very fast, sometimes within days. Even fabric that never touched the floodwater absorbs musty odor from the air in the room, so it smells even though it looks clean.

Polyester and other synthetics resist mold better, but they are notorious for holding onto odors. A mixed stock of natural and synthetic garments therefore suffers in two ways at once: natural fibers grow mold, and synthetic fibers trap smell.

Health risks

• Skin rashes and infections. Clothing that touched floodwater and has not been properly washed may carry bacteria, which can cause itchy rashes or inflamed hair follicles for the person who wears it.
• Mold spores and allergies. Opening bags and shaking out moldy garments releases spores into the air. Sellers and helpers sorting stock may sneeze, become congested or suffer asthma flare-ups.
• Germs from floodwater. Mud in the storage room may be contaminated with bacteria such as E. coli. Wash your hands every time after handling muddy stock.
• Leptospirosis. Storage rooms full of fabric sacks are a favorite hiding place for rats. Wear boots and gloves while cleaning up.

Damage to sales

For a clothing business, smell is the very first thing a customer notices, before the print, the color or the size. A musty shirt will not sell, and if it does, the customer may never come back. A single review in an online group saying "the shirt arrived smelling musty" can wipe out a month of sales for an online shop. Damaged stock is also money already spent, and every day it sits untreated, mold spreads further into the stock that is still good.

Weekend stall sellers face an extra time pressure. A stall that does not open loses not only that weekend's revenue but also visibility; regular customers may find another seller nearby. Getting stock back to a sellable condition quickly is often the difference between a bad month and a lost season.

Spots that are easy to overlook in a stockroom

• Sacks in the middle rows that did not get wet but were pressed against wet ones.
• The back of clothing rails pushed against the wall, where air does not flow.
• Plastic and wooden hangers with dried mud on them.
• Crates and folding tables used for the stall, stored on the ground floor during the week.
• Stall canopies and tablecloths that were folded away while still damp.
• Mannequins and display stands, especially fabric-covered ones.

Fixes That Many Sellers Try, and Why They Do Not Work

Spraying perfume or fabric freshener and selling right away. A pleasant scent masks the musty smell only briefly. Once the customer wears the garment and starts to sweat, the odor comes back, and the mold in the fibers is still there.

Sun-drying without washing. Sunlight helps dry fabric and reduces some odor, but it does not remove the mud and germs that came with the floodwater. Clothing that was submerged must always be washed first.

Washing everything with bleach. Bleach fades colored clothing and damages some fabrics. It is only suitable for white fabrics that tolerate it, and it does nothing for the room the clothes will go back into.

Putting washed stock straight back into the same room. If the room still smells musty and spores are still floating in the air, freshly washed clothes will absorb the smell again within days. This is the most common reason sellers feel they "washed everything and it still smells".

Running fans throughout the room. Fans help remove humidity, but they also blow spores from moldy sacks onto other sacks, spreading the problem further.

The common thread in all of these shortcuts is that they treat the garment in isolation. Clothing stock is a system: the fabric, the bags and boxes it is packed in, the shelves and rails it sits on, and the air in the room all exchange moisture and odor with one another. If any part of that system is still damp or moldy, it will keep feeding the problem back into the clothes. A lasting fix has to address every part at the same time, which is why washing, room disinfection, ozone treatment and better storage work best as one coordinated plan rather than as separate attempts spread over several weeks.

A Fabric-by-Fabric Guide to Saving Flood-Affected Stock

Not every garment reacts to floodwater, mold or ozone in the same way. Knowing how each material behaves helps you decide what to wash, what to treat, what to test and what to let go. The notes below are practical starting points; always read the care label, and when a piece is valuable, test a small hidden area first.

• Cotton T-shirts and casual cotton wear: the most forgiving category. Submerged items can usually be washed in warm water with detergent and dried completely in the sun. If black mold spots remain after two washes, the item is generally not worth selling.
• Linen and rayon dresses: these absorb water quickly and wrinkle or shrink easily. Wash gently according to the label, dry flat or on a hanger in the shade, and check seams and hems carefully for hidden spots.
• Polyester and sportswear: mold grows less readily on synthetics, but odor clings stubbornly. These are good candidates for ozone treatment after washing, but pieces with spandex should receive a controlled, shorter exposure.
• Denim: heavy denim takes a long time to dry, which gives mold time to grow inside the seams and pockets. Turn jeans inside out and make sure they are dry all the way through before storage.
• Silk and brightly dyed fabrics: these are the most sensitive to both bleach and high ozone concentrations. Hand wash if the label allows, and test ozone on one piece before treating a batch.
• Items with rubber prints, sequins or glued decorations: water can loosen adhesives, and rubber prints can crack with strong ozone exposure. Set these aside and treat them separately with the team's advice.
• Leather and faux leather accessories: bags, belts and shoes that sat in floodwater are difficult to save. Wipe and dry those that only got damp, and keep them out of high-dose ozone treatment.

Grouping your stock this way also makes the ozone stage more efficient, because garments of similar sensitivity can be treated together at an appropriate dose.

The Solution: Sort, Wash, Then Restore the Stockroom with Ozone Treatment and Disinfection Fogging from WHD

The key to saving clothing stock is to deal with both the products and the room where they are kept. World Health Disinfection (WHD) provides an ozone treatment service that breaks down odor molecules trapped in the room and in fabric, and reduces airborne mold spores. This is combined with a disinfection fogging service using Chemgene HLD4H on floors, walls, shelving, rails and stall equipment.

Step-by-step process for clothing shops and market stalls

1. Site survey. The team inspects the stockroom, assesses the damage to stock, identifies mold and high-humidity zones and plans which areas to treat first.
2. Sorting the stock. Separate items into three groups: submerged items with obvious stains or mold, items that were not submerged but smell, and items that are still fine. Submerged items must be washed first, or discarded if badly damaged.
3. Clean-up and fogging of the room. Remove mud and wash floors, then fog with Chemgene HLD4H using a ULV fogger across floors, lower walls, shelves, rails, crates and folding tables, without spraying directly onto the clothes.
4. Ozone treatment of the stockroom. The room is sealed and treated with a controlled dose of ozone to reduce musty odor and airborne spores. No people, pets or plants may be inside.
5. Ozone treatment of washed, dry clothes that still smell. Garments are hung spaced out on rails so air can pass between them, then treated at a suitable dose and duration. High concentrations or overly long exposure can fade some dyes and make elastic and spandex degrade faster.
6. Ventilation. Doors and windows are opened for the period the team specifies, until the ozone has broken down into oxygen, before anyone re-enters.
7. Re-check and storage advice. Odor is checked again, and the team advises on storing stock in raised, lidded plastic boxes.

For online sellers who use their home as a warehouse

Many online clothing shops in Chatuchak and Lat Yao use the living room or a ground-floor bedroom to store stock and pack orders. That means the household is breathing the same air as the moldy stock. Recovery should therefore cover both the storage space and the living space. The team helps plan the order of rooms, the time the family needs to be out of the house and the ventilation period, so that both the family and the stock are safe and the shop can get back to packing orders as quickly as possible.

Planning around the weekend

For stall sellers, timing matters. A practical plan is to sort and wash on Monday and Tuesday, have the stockroom fogged and treated with ozone midweek, treat washed garments that still smell in batches, and restock the room on Thursday or Friday once it has been ventilated and checked. Not every item will be ready for the first weekend back, and that is fine. Bringing a smaller selection of clean, fresh-smelling stock is far better for your reputation than bringing everything and having customers notice an odor.

Being open with customers

Customers in Bangkok know the city has just been through a flood, and many will quietly wonder whether the clothes on a stall were affected. Being open about what you did can turn that worry into trust. A small sign at the stall or a short post on your shop page explaining that stock was sorted, washed, treated and stored in a disinfected room shows professionalism. Online sellers can add a line to their product descriptions for the next few weeks. Honest communication, combined with clothes that genuinely smell fresh, protects your reputation far better than staying silent and hoping nobody notices.

Before and After Restoring Stock and Stockroom

Customer Voice (Example Scenario)

"At first I thought I would have to throw out the whole room. The team helped me sort everything into piles: the submerged items went to the wash first, the ones that only smelled were hung up for ozone, and the room was disinfected at the same time. They also warned me about shirts with elastic and rubber prints, so I set those aside for a test first. The following Saturday I had stock on the stall again, and none of my regulars said a word about the smell."

- Nutchari, weekend market clothing seller, Chatuchak (example scenario)

Checklist for Handling Clothing Stock After the Flood

• Wear gloves and a mask when opening bags and sorting stock.
• Pull submerged clothing out and wash it immediately. Do not leave it sealed in bags.
• Wash according to fabric type, using warm water where the fabric allows, and dry completely before folding.
• Discard muddy cardboard boxes and sacks, and switch to lidded plastic boxes.
• Raise shelves or stock boxes at least a hand-span off the floor and slightly away from the walls.
• Put moisture-absorbing packs in stock boxes and run a dehumidifier in the stockroom.
• Check the smell of stock before every market day for the first one to two months.
• Wash and fully dry stall canopies and tablecloths before folding them away.
• Wipe hangers, rails and mannequins with disinfectant before putting clean stock back on them, so they do not transfer mold or mud to freshly washed garments.
• Keep a short written record of what was washed, treated, tested and discarded, so you can plan restocking and talk confidently with suppliers and customers.

Frequently Asked Questions

Q: Can I use ozone treatment without washing the clothes?
A: Clothing that was submerged or muddy must always be washed first, because ozone does not remove dirt. For clothes that were not wet but picked up musty odor from the room's air, ozone treatment helps reduce the smell well.

Q: Will ozone fade the colors?
A: High concentrations or overly long exposure can fade some dyes. The team controls dose and time, and recommends testing a sample first for brightly colored fabrics or silk.

Q: What about clothes with elastic or rubber screen prints?
A: Rubber degrades faster at high ozone concentrations, so these items should be set aside or treated at a dose set by the team.

Q: Can a small stockroom in a townhouse be treated?
A: Yes. The team adjusts the ozone dose to the room size and advises on sealing the room so ozone does not leak into occupied areas.

Q: How long does it take?
A: Fogging and ozone treatment of a stockroom, including ventilation, usually takes one day. Treating garments in batches depends on the volume of stock.

Q: Can shophouse boutiques or mall stores use the service?
A: Yes, both the shop floor and the stockroom. Call 065-556-6294 or message LINE @whd268 to book a survey.
