Replace pumice without losing the stonewash look.
Reusable HMS stones and dry-process tools for industrial denim and garment finishing. Built to reduce sludge, material use, water levels, transport weight, and process complexity.
Patented technology. ZDHC-approved binders. Supplied to 20+ countries. Industrial trial support available.
THE PROBLEM
Pumice creates more than a fade. It creates waste.
Pumice has shaped denim for decades. But for modern laundries and brands, it creates daily operational problems.
It breaks down quickly.
It creates heavy sludge.
It leaves dust on garments.
It often requires extra rinsing.
It adds transport and storage pressure.
It can damage machines and block systems.
It makes production harder to control.
HMS was created to keep the stonewash effect while removing the biggest problems behind it.

INDUSTRIAL HMS STONES
Reusable stonewashing media for real laundry conditions.
HMS Original and HMS Light are designed to replace pumice in industrial washing processes.
They are hydrophobic, long-lasting, and porous. This helps them create abrasion while reducing water absorption, sludge, and process mess.
HMS can be tested in existing machines and compared directly with pumice using controlled trial recipes.
HMS Original
The main HMS stonewashing medium for denim and garment washing.
Best for:
- Standard denim stonewashing
- Vintage wash effects
- Rigid denim
- Higher-weight fabrics
- Pumice replacement trials
- Industrial laundry use
HMS Light
A lighter HMS stonewashing medium for delicate and sensitive fabrics.
Best for:
- Delicate fabrics
- Recycled fibers
- Stretch denim
- Tencel
- Lightweight garments
- Soft-touch fabrics
- Controlled abrasion with better fabric care
HMS HexaCore & HMS SuperSnow
A specialized HMS solution for acid wash and chemical-carrying applications.
Best for:
- Acid wash effects
- Reduced traditional carrier waste
- Controlled chemical delivery
- Industrial R&D and technical trials
DRY-PROCESS TOOLS FOR FACTORIES
Durable tools for whiskers, surface abrasion, and hand finishing.
HMS Designer Pen and HMS Moon are not only creative tools. Factories can also use them as durable alternatives to sandpaper for dry-process applications.
They can support:
- Whiskers
- Surface abrasion
- Hand finishing
- Sample development
- Repair and detail work
- Controlled abrasion effects
- Training and workshop use
For factory use, bulk orders are handled by email inquiry only.
Minimum order quantity: 250 pieces
HMS DESIGNER PEN FOR FACTORY USE
HMS Designer Pen for factory use
A handheld abrasion tool for detail work, whiskers, and controlled fading.
For factories looking for a more durable alternative to sandpaper in dry-process finishing.
MOQ: 250 pieces
HMS DESIGNER MOON FOR FACTORY USE
HMS Designer Moon for factory use
A larger handheld abrasion tool for broader surface effects, whiskers, and texture work.
Designed for hand-finishing teams that need control, grip, and durability.
MOQ: 250 pieces
COST SAVINGS
Less sludge. Less material. Less hidden cost.
Pumice cost is not only the purchase price of the stone.
It also includes transport, storage, labor, rinsing, sludge treatment, machine wear, downtime, and quality inconsistency.
HMS helps reduce these hidden costs by using less material, creating no pumice sludge, lowering transport weight, reducing handling, and supporting cleaner wash processes.
37.5x more durable
HMS lasts far longer than pumice, reducing material replacement needs.
Lower operational pressure
Less inbound stone volume, less storage, less cleaning, and less waste handling.
97% less material
Selected cost models compare 0.02 kg HMS per garment with 0.8 kg pumice per garment.
Disclaimer:
All savings are model-based and depend on site conditions, recipe, machine type, local water coscost, sludge treatment cost, labor cost, and production volume. Final results should be validated through a site-specific trial.t, energy
No sludge disposal cost
HMS does not create pumice sludge, removing a major cost category for many laundries.
Higher capacity potential
Selected models compare 200 garments per HMS batch with 100 garments per pumice batch, depending on machine and process setup.
SAITEX CASE STUDY
Case study: Saitex reduced sludge and transport volume while keeping the look.
Saitex, a large-scale denim manufacturer in Vietnam, faced the same challenge many laundries face: rising sludge treatment costs, heavy pumice logistics, and pressure from global brands to reduce environmental impact.
By using HMS, Saitex reported approximately:
- 90% less sludge volume
- 90% less transport weight
- 100% maintained wash aesthetics
“Compared to traditional pumice stones, HMS has allowed us to reduce both transportation and sludge volume by approximately 90%.”
WHY BRANDS CARE
A cleaner supplier solution brands can actually ask for.
Brands need more than good intentions. They need suppliers to adopt practical solutions that work on the factory floor.
HMS helps brands support cleaner denim finishing without giving up the aesthetics customers expect.
HMS can help brands:
- Reduce pumice-related waste in their supply chain
- Support supplier innovation
- Lower sludge-related impact
- Improve sustainability reporting
- Create stronger product stories
- Move toward cleaner denim washing with real production partners
INDUSTRY TO CREATIVE CROSSOVER
Looking for workshops or creative tools?
HMS is not only a production solution. We also offer hands-on workshops and creative tools for factories, brands, schools, retail spaces, and events.
Factories can use HMS workshops for staff training, customer visits, team activities, and sustainability education.
HMS Designer Pen and HMS Moon can also be used as durable dry-process tools for whiskers, surface abrasion, hand finishing, and sample development.
WHY LAUNDRIES CARE
Built for the daily pressure of washing floors.
Laundries need solutions that work inside real production, not ideas that only sound good in a presentation.
HMS helps reduce sludge, dust, rinsing, storage pressure, stone replacement, machine stress, and process inconsistency.
For laundries, HMS can support:
- Cleaner machines
- Less waste handling
- Lower water levels
- Reduced garment dust
- More consistent abrasion
- Better customer-facing innovation
- Lower long-term operating costs
