A Story from the Field: Auntie Boonruean's Teak Cabinet

Auntie Boonruean is sixty-one years old and chairs the weaving group in a village in Bang Rachan District, Sing Buri Province. Her group has a little more than ten members, most of them women who weave in the afternoons and evenings once the work in the rice fields is done. Between them they produce silk, cotton ikat (mudmee) and the checked cotton cloth known as pha khao ma. Everything they make is sold from a small shop at the front of Auntie Boonruean's house, a regular stop for visitors who come to see the historic Bang Rachan camp, and it also travels to provincial OTOP fairs several times a year.

This year the water came faster than anyone expected. Auntie Boonruean and the members managed to carry part of the stock upstairs, but not all of it. The fabrics in the lower half of the old teak cabinet, the folded pieces still waiting for price tags, and several skeins of silk yarn that had only just been dyed were still in the storeroom behind the shop when the water seeped in and rose to almost half a meter.

Two weeks later, when the water had finally gone down, she opened the storeroom door and had to pull a cotton cloth over her nose. A heavy, damp, muddy smell rolled out at once. An indigo silk on the bottom shelf was covered in grey-green spots spreading out in rings. Several cotton pieces carried sharp tide lines where the water had stopped. The fabrics on the top shelves looked normal at first glance, but when she held them up to her face, the musty smell was there too.

The advice started immediately. One member suggested wiping the spots with bleach. Another said to put everything out in the strong afternoon sun. Her daughter, who works in town, said she had seen ozone treatment offered for hotel rooms and thought it could probably be used on fabric as well. Auntie Boonruean sat looking at the pile of cloth that had taken months of handwork and asked the only question that really mattered: "Which of these will not make the damage worse?"

Her question is the heart of this article. A handwoven textile shop is not an ordinary house. Silk is a delicate protein fiber, natural dyes fade easily, and methods that work perfectly well on a concrete wall or a tiled floor can quietly ruin a length of cloth that took weeks to weave. Getting the order of steps right is what separates a shop that recovers most of its stock from one that loses it.

The Real Problems a Textile Shop Faces After the Water Recedes

1. Mold on fabric is damage that keeps spreading. Mold needs moisture and organic material, and natural fibers like silk and cotton are exactly the kind of food it likes. If the spots are left alone, they widen, leave stains that cannot be washed out, and in some cases weaken the fibers so much that the cloth tears easily at that point. Every day of delay in a humid room gives the mold more time to work.

2. The storeroom itself becomes the source of spores. Even after every piece of fabric has been carried out, the plaster walls, wooden cabinets, shelves and floor that sat in floodwater still hold moisture and mold spores. If carefully dried fabric is put back into the same untreated room, the chance of it going moldy again is high. Many shop owners discover this a month after the flood, when spots reappear on cloth they thought was saved.

3. The health of the people who work there. Floodwater carries whatever was in the drains and sewers, including bacteria that cause diarrhea and the organisms linked to leptospirosis, which can enter the body through small cuts and scratches. Members who carried soaked fabric with bare hands may have been exposed without realizing it. Meanwhile, mold spores in a closed, damp room can trigger allergies, coughing, sneezing and asthma, and many members of village weaving groups are older adults who spend long hours sitting at the loom in that same air.

4. The reputation of an OTOP product. People who buy handwoven silk expect it to smell clean and look perfect. Even a faint musty smell makes them hesitate, and if a customer later finds a hidden mold spot on a piece they bought as a gift, the trust a group has built over many years can be hurt in a single conversation. Word travels quickly in community markets and online groups.

5. Money and time. A single length of silk can take days or weeks to weave. Most of a weaving group's capital sits in finished stock and dyed yarn. A wrong decision in the first few days, such as bleaching a spot or leaving silk in harsh sun, can turn a piece that could have been rescued into a total loss. The goal is to protect as much of that work as possible.

Why the Usual Fixes Do Not Suit a Silk Shop

• Wiping mold spots with bleach: Chlorine bleach attacks the protein fibers of silk and strips dye. The likely result is a pale blotch or a weakened patch exactly where the spot was. It also does nothing about the spores that remain in the room and in the air.
• Drying everything in strong sun all day: Hard sunlight dries cloth quickly, but it also fades natural dyes and degrades silk. Most handwoven fabrics are better aired in shade with a good breeze, turned regularly until they are completely dry.
• Turning on fans and waiting: Fans help the surface of fabric dry, but they do not dry walls and wooden cabinets deep down. They can also blow spores from the walls onto clean pieces of fabric elsewhere in the shop.
• Air freshener or scented sachets: These cover the smell for a short time but do not kill mold. Some customers are sensitive to strong fragrance, and the musty odor comes back as soon as humidity rises again.
• Repainting the walls straight away: New paint hides stains, but if the wall is still damp, mold pushes the paint into bubbles within weeks, and the smell stays in the room.
• Running ozone in the room with the fabric still inside: This is the most important point of all. Ozone is a strong oxidizer. Long or concentrated exposure can fade natural dyes and weaken silk fibers. That is why the team recommends that silk, valuable handwoven pieces and dyed yarn be taken out of the room before any ozone treatment.

Step One: Sort the Fabric into Four Piles Before You Call Anyone

Before thinking about disinfection, take the fabric out of the room and sort it by condition. Always wear rubber gloves, a well-fitting mask and boots. Work in a shaded area with good airflow, and write down and photograph each pile as you go. That record helps when the group applies for assistance or needs to estimate its losses for members and partners.

• Pile 1, completely dry, no smell, no spots: These are usually the pieces from the top shelves that never touched the water. Wrap them in clean cotton or acid-free tissue paper and move them to a dry room for now. Avoid sealing them in plastic bags, because any remaining moisture will be trapped inside.
• Pile 2, musty smell but not directly flooded and no spots: Air these in shade with a steady breeze for several days, turning them often. Fabrics that the group normally washes, such as some cottons, can be washed in the usual way once they are out of the damp room.
• Pile 3, mold spots or water marks on valuable pieces: Set these aside in clean cloth bags. Do not scrub, do not rub hard and do not try chemicals yourself. Ask someone who specializes in silk care, an experienced dyer, or a dry cleaner who handles silk to assess how much can be recovered.
• Pile 4, soaked for a long time, mud or wastewater inside, mold across the whole piece: These pieces were directly contaminated by floodwater. If they cannot be cleaned properly, remove them from the sales stock. Never put them back on the shelf for customers.

Undyed or dyed yarn that sat in floodwater is usually difficult to recover, because fine mud works deep into the fibers. Wooden looms should have the mud washed off, be wiped dry and be moved somewhere airy to dry out as well as possible before the room is treated.

Important: WHD disinfection and ozone treatment are designed to restore the room, not to wash or repair textiles. The team does not spray disinfectant directly onto silk, and does not run ozone with valuable fabric inside the room.

The Solution: Disinfection Fogging and Ozone Treatment for the Storeroom with WHD

Once the fabric has been moved out and sorted, the next job is to make the storeroom, the shop floor and the wooden cabinets a safe place to keep textiles again. World Health Disinfection (WHD) uses two main steps that support each other.

Disinfection service using CHEMGENE HLD4H disinfectant applied with an ultra-low-volume (ULV) fogger. The droplets are very fine, so they drift into cabinet joints, room corners, beneath shelves and across wall surfaces that a cloth simply cannot reach. This helps reduce the germs that floodwater left on surfaces throughout the room.

Ozone treatment service. Ozone is a gas that spreads through the whole room. It helps deal with mold spores in the air and on surfaces, and it breaks down the molecules behind musty, muddy and stagnant-water smells rather than covering them up. The team calculates the dose and duration for the size of the room and uses a Master Ozone Generator at a controlled output.

How the Work Is Done in a Handwoven Textile Shop

1. Site survey: The team looks at the storeroom, the shop front, the weaving area and the cabinets, notes how high the water rose, and checks where mold is growing and which spots are still damp.
2. Preparation advice: The team confirms that silk, handwoven pieces, yarn, paper price tags and the group's account books have all been moved out. They also advise on removing mud, wiping down surfaces and discarding materials that have absorbed too much water to save, such as collapsed cardboard boxes.
3. Disinfection fogging: Fine mist is applied through the empty room, covering walls, floors, wooden cabinets, shelves and the shop counter.
4. Ozone shock treatment: The room is sealed with no people, pets or plants inside. Electronic items that cannot be moved, such as a cash register, are covered. The team controls time and concentration according to room size.
5. Ventilation: Doors and windows are opened so the ozone can break down back into oxygen before anyone goes back in.
6. Re-check and advice: The team checks smell and damp spots again, gives advice on long-term fabric storage, and arranges a follow-up if any area is still holding moisture.

Ozone safety: No people, pets or plants may be in the room during treatment. After treatment the room must be ventilated until the ozone smell is gone before anyone re-enters. In a textile shop, silk, naturally dyed fabric, rubber items and sensitive electronics should be removed from the room or fully covered as the team advises.

10 Reasons a Weaving Group Should Restore Its Storeroom Properly

1. Break the cycle of repeat mold: A room that has been through ozone treatment holds fewer spores, so fabric that comes back is not returning to the same source of mold.
2. Reduce floodwater germs: Disinfection fogging helps reduce germs on the floors, walls and cabinets that members touch every day.
3. Reach places hands cannot: Fine droplets drift under cabinets, behind shelves and into the joints of old wooden furniture.
4. Remove the smell rather than mask it: Ozone breaks down musty and muddy odor molecules, so customers walking in notice a clean shop, not a perfumed one.
5. Protect high-value stock: Fabric is taken out before treatment. The room is cleaned, and the cloth is never exposed directly to strong agents.
6. Look after members' health: Older members who sit at the loom all day breathe air with fewer spores in it.
7. Use a disinfectant designed for the job: CHEMGENE HLD4H is used for surface disinfection, so there is no need for harsh bleach fumes near precious cloth.
8. Ready to welcome visitors again: A clean, odor-free shop is ready for travelers stopping in Bang Rachan once roads reopen.
9. Ready for trade fairs: Fabric stored in a clean room does not carry a musty smell to the OTOP booth.
10. Ongoing advice: If smell or damp returns, the team can be reached by LINE or phone, and you can read more about residential ozone disinfection in the meantime.

Before and After Restoring the Storeroom

How to Store Silk Once the Room Has Been Restored

• Wait until the room is truly dry: After treatment and ventilation, leave the room open and empty for a while longer. Watch the walls for any new damp patches before bringing fabric back.
• Raise the shelving: Valuable pieces should sit on shelves well above floor level and away from any wall that was damp.
• Wrap fabric in breathable material: Clean cotton or acid-free tissue works better than sealed plastic bags, which trap moisture.
• Refold from time to time: Silk that stays folded in the same place for months weakens along the creases. Unfold and refold it differently every few months.
• Use moisture absorbers with care: Place them in the room but never in direct contact with fabric, and replace them on schedule.
• Do not put mothballs directly on fabric: The smell clings to the cloth and customers dislike it. Rely on a clean, dry room instead.
• Check stock every month during the rainy season: Unfold pieces, look for spots and smell them. If you find a problem, separate that piece immediately.

If the weaving room has mattresses or seat cushions that members use every day, the dust mite removal service can be added. If mosquitoes have become a problem around the house since the water went down, see the mosquito spraying service as well.

A Practical Week-by-Week Plan for Small Weaving Groups

Many groups are run by volunteers who also have farms and families to look after, so it helps to break the recovery into simple stages rather than trying to do everything in one weekend.

Days 1 to 3, safety and sorting. Check that electricity in the shop is safe before switching anything on. Put on gloves, masks and boots. Carry all fabric out to a shaded, breezy area and sort it into the four piles described above. Photograph everything. Discard soaked cardboard, paper packaging and anything that is clearly beyond saving. Wash off thick mud from the floor and the lower parts of the walls with clean water.

Days 4 to 7, drying and assessment. Keep airing Pile 2 in shade. Contact a silk care specialist or dry cleaner about Pile 3. Open every door and window in the storeroom during the day to start drying the walls. Pull the cabinets slightly away from the walls so air can circulate behind them. This is also a good time to call WHD for a site survey, so the treatment can be scheduled as soon as the room is ready.

Week 2, room treatment. With the room empty and the mud removed, the team carries out disinfection fogging and ozone treatment, followed by ventilation. Members can use this time to repair price tags, update the stock list, and plan which pieces will go to the next fair.

Weeks 3 to 4, careful return. Once the walls show no new damp and the room smells fresh, bring back Pile 1 first, then Pile 2 once it is fully dry and odor-free. Keep Pile 3 separate until its condition has been confirmed. Watch the room closely for the first month, especially after heavy rain.

This kind of plan also makes it easier to explain the situation to members, customers and anyone offering support, because everyone can see what has been done and what comes next.

Customer Voice (Example Scenario)

"At first I was afraid ozone would fade our silk. Once the team explained that we should take the fabric out first and only treat the room and the cabinets, I felt much better. The badly spotted pieces went to someone who really knows silk. Now I can walk into the storeroom without covering my nose, and the members are back weaving the way they used to."

Frequently Asked Questions

Q: Can I ozone silk directly to remove the smell?
A: It is not recommended. Ozone is an oxidizer that can fade natural dyes and weaken silk fibers. The team asks for silk and valuable fabric to be removed first, and then treats only the room and furniture.

Q: Can fabric with small mold spots still be sold?
A: It depends on the cloth and on proper care. Have a silk specialist or a dry cleaner who handles silk assess it. Fabric that soaked in floodwater with mud inside should not go back on sale.

Q: Can I wipe the wooden cabinets with bleach?
A: It may suit some surfaces, but it should not be used near fabric, because fumes and splashes can mark the cloth, and bleach does not deal with airborne spores. Fogging and ozone in an empty room are more suitable.

Q: How long does the shop need to close?
A: It depends on room size and how damp it is. The team gives an estimate during the survey and normally plans the work so treatment and ventilation are finished before the space is used again.

Q: Do wooden looms have to be moved out?
A: Wooden looms that have been cleaned of mud and wiped dry can stay in the room during fogging and ozone treatment, but any yarn or half-woven cloth on the loom should be removed first.

Q: Which areas do you cover?
A: Bang Rachan, Mueang Sing Buri, In Buri, Phrom Buri, Khai Bang Rachan, Tha Chang and nearby areas. Ask about available dates by phone or LINE.

Q: What if the smell comes back after treatment?
A: That usually means a wall or floor is still damp deep inside. Let the team know so they can find the damp area and deal with the cause before considering another treatment.
