A Story From the Field: The Most Important Selling Season of the Year

Auntie Muay has run a shop selling school uniforms, school shoes, bags and textbooks from a shophouse near the market in Mueang Phitsanulok for more than twenty years. The weeks before a new term are her busiest of the year. Parents bring their children in to try on shirts, shorts and skirts, have names and school badges embroidered, and pick up the textbooks on each school's list. Her shelves are stacked with white shirts folded in plastic bags, rows of shorts and skirts on rails, towers of shoe boxes and piles of newly delivered textbooks.

This year the Nan River overflowed into the town. Water rose almost to knee height inside the shop and stayed for several days. Auntie Muay and her son managed to carry some stock upstairs, but a great deal of merchandise on the lower shelves and in the stockroom at the back went under.

When the water went down, the first thing she noticed was the musty dampness hanging in the air. Bags of shirts on the bottom shelves had muddy water trapped inside. White shirts were dotted with grey-black mold. Shoe boxes had collapsed. Textbooks had swollen into wavy blocks with pages glued together. The embroidery corner and sewing machines were coated in mud, and a long water line ran across the back wall.

School was due to start in just a few weeks. Parents began phoning to ask when the shop would reopen, and some asked directly: "Are the uniforms in your shop safe? My child has allergies." Auntie Muay knew that what she sells ends up on children's bodies every single day, so she had to get this right from the start.

If you own a school uniform shop, a textbook shop, a stationery store or an embroidery business in Mueang Phitsanulok, Bang Krathum or nearby, this article will help you plan the work so the shop is ready before term begins.

Why a Uniform Shop Needs a Careful Recovery

Flood-soaked stock should not be sold as new

Floodwater that has passed over roads and through drains is often contaminated with sewage and bacteria such as E. coli. The cotton and blended fabrics of school uniforms soak dirty water into the weave, the seams and the linings. Even after washing, they may keep yellow stains, mold spots or a musty smell. Children wear their uniforms against their skin all day, so a shop should not put flood-soaked items back on sale as new. Set them aside, record them and talk to your supplier or insurer about what to do with them.

Wet textbooks are almost impossible to save

Paper that has been soaked in floodwater swells, sticks together and can grow mold within days. Wet textbooks should be pulled from sale and kept away from dry stock, because mold spores spread from book to book.

Children with allergies react to mustiness and mold

Children with allergies or asthma may start sneezing, feel congested or have trouble breathing when they try on clothes in a shop with mold spores in the air. Fitting rooms, small spaces closed off by a curtain, are usually the dampest spots of all. Adults wading through water during clean-up face a higher risk of leptospirosis, diarrheal illness and fungal skin infections, so rubber boots, rubber gloves and a mask are essential.

Very little time before term starts

A uniform shop depends on the back-to-school rush. If you cannot open in time, parents will buy elsewhere and may not come back. But if you rush to open while the shop still smells musty, they may not feel confident buying either.

Step One: Sort the Stock

• Remove from sale: uniforms, socks, PE kits and every textile item that sat in floodwater or has water trapped inside its plastic bag. Photograph and list them, then talk to your supplier or insurer. Do not wash them and put them back on the shelf as new.
• Remove from sale: textbooks, exercise books, paper and cardboard boxes that got wet.
• Remove from sale: canvas shoes, leather shoes and bags that sat in floodwater, since soles and inner padding hold dirty water.
• Wash and disinfect: metal shelving, plastic hangers, plastic mannequins, counters and glass. Wash off the mud first, then disinfect and wipe dry.
• Call a technician: sewing machines, embroidery machines, computers and any electrical system that was under water should be checked before use.
• Undamaged stock: items from high shelves whose bags are still sealed and odor-free should be moved to a dry place while the shop is being cleaned.

Why the Familiar Fixes Fall Short

Washing flooded uniforms and selling them

Washing removes visible dirt, but fabric that sat in floodwater for days often keeps yellow stains and mold in the seams. Parents also buy uniforms expecting them to be new. Selling these items risks both children's health and your customers' trust.

Perfume or air freshener in the shop

Fragrance covers mustiness for a short while and can trigger symptoms in sensitive children. The root causes, mold and moisture in walls, ceilings and fitting rooms, remain.

Fans alone

Fans help things dry faster, but they do not kill anything and can blow mold spores onto stock that is still good.

Painting over mold

If the wall is still damp and the mold is alive, black spots will be back within weeks. Dry, clean and disinfect the wall before painting.

The Solution: Ozone Treatment and Disinfection Fogging of the Empty Shop by WHD

Once damaged stock has been set aside, good stock moved somewhere dry, mud washed out and the electrics checked, the World Health Disinfection (WHD) team deals with the germs, mold and musty odors that remain, using two methods.

1. ULV disinfection fogging

The team uses CHEMGENE HLD4H disinfectant in an ultra-low-volume fogger that creates a very fine mist. It reaches shelving, counters, fitting rooms, the stockroom and corners that hands cannot reach, helping reduce bacteria and mold on surfaces. Details are on the disinfection service page.

2. Ozone treatment

After fogging, the shop is closed and a professional ozone generator runs at a controlled dose for a set time. Ozone helps destroy airborne mold spores and break down musty odor molecules embedded in walls, ceilings, fitting-room curtains and carpets. Read more about the ozone treatment service.

How the work runs

1. Site survey: the team checks the flood line, mold, fitting rooms, the stockroom, the embroidery corner and ventilation.
2. Clean-up advice: guidance on separating damaged stock, removing mud and washing surfaces.
3. Preparing the space: good stock, plants, pets and people leave the shop. Computers, embroidery machines and delicate electronics are covered or moved, along with shoes and any goods with rubber parts.
4. Disinfection fogging: CHEMGENE HLD4H mist is applied throughout the shop, fitting rooms and stockroom.
5. Ozone treatment: the shop is sealed and treated according to its size. No people, pets or plants may be inside.
6. Ventilation: doors, windows and fans are opened until the ozone has broken down, before people return and stock goes back on the shelves.
7. Re-check: the team checks for odor and mold and advises on humidity control in the stockroom.

Safety note: during ozone treatment there must be no people, pets or plants in the shop, and it must be fully ventilated before anyone goes back in. Colored textiles and shoes with rubber components should be moved out or covered, because high ozone concentrations can degrade rubber and fade some dyes. The team controls the dose according to the site.

Handling Textbooks, Exercise Books and Paper Stock

Paper is one of the hardest materials to rescue after a flood. A textbook that sat in floodwater absorbs water from the edges inward, the pages swell and stick, and mold often starts growing in the spine within two or three days. Even if a book dries flat, it may keep stains and a musty smell that parents will notice immediately.

For a shop, the practical approach is straightforward. Pull every wet book, exercise book, notebook and paper product off the shelves and keep them in a separate, clearly labeled area away from dry stock. Photograph them with their labels visible, list the titles and quantities, and contact your publisher or distributor about replacements. Do not stack damp books with dry ones, and do not keep wet paper in the stockroom while you wait for a decision, because spores travel easily between books.

Books that were stored above the water line and are still in sealed shrink-wrap are usually fine, but check each pack for condensation inside the plastic and for any musty smell. Move them out of the shop to a dry room while the shop is fogged and ozone-treated, and bring them back only after ventilation is complete. Keeping paper stock in lidded plastic crates in future will make the next wet season much less stressful.

Before and After the Shop Recovery

What a Shop Owner Might Tell You (Example Scenario)

"It broke my heart to set aside hundreds of uniforms, but I thought, if this were my own child, I would not want them wearing something that had been in floodwater. Once the new stock arrived, the team fogged and ozone-treated the shop before we put anything out. The musty smell that had been stuck in my nose was mostly gone, and none of the parents who brought their kids in to try things on complained about the smell again."

— Auntie Muay, school uniform shop owner, Mueang Phitsanulok (a representative scenario based on field work)

A Back-to-School Recovery Timeline

Because the school calendar will not wait, it helps to work backward from the day term starts. Every shop is different, but the following sequence keeps the most important jobs in the right order.

As soon as the water leaves

Keep the power off until an electrician has checked the shop. Photograph the water line, damaged stock and the stockroom. Call your uniform and textbook suppliers immediately to reserve replacement stock, because every shop in the area may be reordering at the same time.

Days one to three

Remove all flood-soaked uniforms, shoes, bags and books from the sales floor and store them separately with a clear label. Take down wet fitting-room curtains. Shovel out mud and wash floors, walls and shelving, then let the shop dry with doors open and fans running.

Once the shop is dry

Book WHD for disinfection fogging and ozone treatment of the empty shop. Make sure good stock, shoes and anything with rubber parts are out of the space or covered, and that sewing and embroidery machines have been checked by a technician.

After ventilation

Hang fresh curtains in the fitting rooms, put new stock on clean shelves, and let parents know the shop is open again. Keep the shop well ventilated every day during the busy weeks, especially the fitting rooms and stockroom.

Setting Up the Shop for Term and for the Next Flood Season

• Keep textiles and books on shelves raised at least to knee height, and use the bottom shelves for washable items like hangers and plastic boxes.
• Store backstock in lidded plastic boxes rather than cardboard, clearly labeled with sizes and school names.
• Ventilate the fitting rooms every day and wash fitting-room curtains regularly.
• Tell parents through LINE or your shop's page that all stock on sale is from new deliveries and that the shop has been cleaned, disinfected and ozone-treated.
• Prepare a plan for moving stock upstairs, with a list of people who can help, before next year's flood season.

Being open about what you did is often the best marketing a neighborhood shop can do. Parents talk to each other at the school gate, and a shop that handled the flood responsibly earns loyalty that lasts well beyond one term.

Shoes, Bags and the Embroidery Corner Need Extra Thought

School shoes and bags

Canvas school shoes, leather shoes and backpacks are built from layers: fabric or leather outside, foam and card inside, and rubber or plastic soles glued together. When floodwater gets into those layers it is very hard to get it out again, and the inside can stay damp long after the outside looks dry. That is why flood-soaked shoes and bags belong with the stock you set aside, not on the shelf. Shoes that stayed dry on upper shelves are fine to keep, but move them out of the shop during ozone treatment, because rubber soles and elastic can be affected by high ozone levels.

The embroidery and alterations corner

Many uniform shops stitch names and school badges on the spot. Sewing machines, embroidery machines and their foot pedals sit low and are often the first equipment to be submerged. Have a technician check them before they are switched on. Thread spools, interfacing and badge stock that got wet should be discarded, and the worktable and chair should be cleaned and dried before the area is fogged.

Carpets, mats and curtains

Entrance mats, carpet in the children's corner and fitting-room curtains soak up floodwater and become a major source of musty odor. Carpets and mats that were under water are usually best replaced. Curtains can be washed hot or replaced. Removing these soft materials before treatment makes fogging and ozone far more effective.

Why Fogging and Ozone Work Better Together

The two methods do different jobs. Disinfection fogging lays a fine film of disinfectant on the surfaces where floodwater germs actually sit: shelves, counters, rails, fitting-room walls and the stockroom floor. Ozone is a gas that spreads through the air of a sealed, empty shop and reaches airborne spores and odor molecules trapped in porous materials such as ceiling boards and painted plaster.

Used one after the other, followed by thorough ventilation, they cover both the surfaces customers touch and the air they breathe. Neither replaces removing mud, setting aside damaged stock and drying the building, and neither turns flood-soaked goods back into new merchandise. Together, though, they give a uniform shop the best chance of a clean, fresh-smelling space before the back-to-school rush.

Working With Schools and Parents

Many uniform shops have long-standing arrangements with nearby schools. If the flood has delayed your opening, let those schools know your expected date so they can tell parents where to buy. If a particular size or badge is going to be short, say so early and offer to take orders by phone or LINE for collection once the shop reopens.

When you do reopen, a simple notice explaining that every item on sale comes from new deliveries and that the shop has been cleaned, disinfected and ozone-treated answers the question many parents are quietly asking. Honest, specific information builds more trust than any promotion. It also helps teachers, who are often asked by worried parents where it is safe to buy uniforms after the flood, to point families toward your shop with confidence.

Frequently Asked Questions

1. Can I wash flood-soaked uniforms and sell them?

We do not recommend selling them as new. Set them aside, photograph them and talk to your supplier or insurer, because fabric that sat in floodwater may hold stains and mold, and children wear uniforms against their skin all day.

2. Can ozone treatment make flooded uniforms sellable again?

Our ozone treatment deals with mold and musty odors in the shop itself. It does not turn flood-soaked goods back into new stock, and colored textiles and shoes with rubber parts should be moved out during treatment.

3. Can it be done before term starts?

The fogging and ozone work itself usually does not take long, but the shop needs to be dry and free of mud first. Contact the team as early as possible so the work can be scheduled before your opening day.

4. How should I look after the fitting rooms after a flood?

Take down wet curtains to wash or replace, clean the floor and walls, include the fitting rooms in the fogging and ozone treatment, and keep them well ventilated afterward.
