Cleaning Sponge

Bulk Industrial Cleaning Sponges & Heavy-Duty Scouring Pads Direct Manufacturer

Engineered for commercial janitorial suppliers, food processing facilities, and industrial maintenance contractors, our bulk cleaning sponges and abrasive scouring pads deliver consistent density, high tensile tear resistance, and robust solvent durability. Manufactured from open-cell polyurethane, regenerated cellulose, and micro-porous melamine resin under strict gravimetric and peel-adhesion quality controls, we provide stable container-load supply, precision die-cutting, and private-label packaging tailored to global B2B distribution requirements.
Material Composition: Open-cell polyurethane (PU) foam, regenerated wood cellulose, compressed melamine, and non-woven nylon fiber abrasive webs.

Technical Specifications

Technical Parameter	Specification	Commercial / Performance Benefit
Material Composition	Open-cell polyurethane (PU) foam, regenerated wood cellulose, compressed melamine, and non-woven nylon fiber abrasive webs	Allows different sponge structures to be selected for wiping, absorption, scrubbing, and heavy-duty cleaning
Density	PU foam: 18–45 kg/m³; Compressed cellulose: 1.2–1.6 g/cm³	Density affects softness, durability, handling, and absorption performance
Tensile Strength	≥120 kPa, tested according to ASTM D3574	Helps reduce tearing and deformation during repeated or aggressive manual scrubbing
Absorption Capacity	Up to 20× dry weight in water	Provides high liquid-holding capacity and reduces the need for frequent rinsing or replacement
Chemical Resistance	Resistant to oil, dilute acids, and commercial quaternary ammonium (quat) sanitizers	Suitable for commercial, industrial, and general-purpose cleaning environments

Multi-purpose Household Cleaning Sponge

Product Type

Cellulose Sponges: Biodegradable wood pulp material; high liquid retention; streak-free wiping on glass, stainless steel, and porcelain surfaces.

Melamine Magic Sponges: Micro-porous melamine resin foam; activated by water alone for erasing scuffs, ink, and grease without chemical cleaners.

Dual-Action Scour Sponges: Combines high-density yellow PU foam with an aluminum-oxide coated abrasive nylon scouring web bonded via heat-setting resin.

Heavy-Duty Griddle Pads: Resin-bonded coarse nylon fiber pads designed for high-temperature (> 150°C) commercial flat-top grill cleaning.

Application Scenarios

Commercial Food Service

Back-of-house dishwashing, stainless steel prep table sanitization, and cast-iron skillet maintenance.

Janitorial Facility Maintenance

Restroom porcelain scrubbing, wall scuff removal, and routine daily surface wiping in schools and offices.

Industrial & Automotive Workshops

Machine tool grease removal, parts degreasing prior to coating, and automotive paint prep wiping.

OEM & Processing

Custom Dimensions: Precision die-cutting, wave-profile slicing, and contoured finger-grip cutting available from 50 mm to 200 mm length.

Private Labeling: Custom printed polybags, insert card branding, barcode labeling, and bulk master carton outer printing.

Bonding Technology: Flame-lamination or moisture-curing polyurethane adhesive bonding prevents pad delamination during commercial use.

Multi-purpose Household Cleaning Sponge

Manufacturing & QC

Foaming & Curing

Continuous slab foaming lines equipped with automated temperature control to maintain uniform cell structure and prevent soft spots.

Density Testing

Gravimetric density verification per batch to ensure consistent weight and foam resilience.

Peel Adhesion Testing

Mechanical pull-testers verify bond strength between scouring webs and foam bases (minimum shear force threshold: 45 N).

Sanitation & Packaging

Automated shrink-wrapping and metal-detector screening prior to export palletization.

FAQ

Q: What is the minimum order quantity (MOQ) for custom-printed polybag packaging?

A: MOQ is 10,000 pieces per SKU for custom printed film; unprinted bulk cartons start at 3,000 pieces per specification.

Q: Are the abrasive scouring pads bonded with waterproof resin?

A: Yes, phenol-formaldehyde resins are cured at 180°C, ensuring the abrasive web remains attached to the sponge even after prolonged immersion in hot water and grease-cutting detergents.

Q: Can cellulose sponges be treated with anti-bacterial agents?

A: Yes, EPA-registered anti-microbial additives can be compounded during pulp processing to inhibit mold and bacterial growth inside the sponge matrix.

Q: What is the standard production lead time for a 40-foot container order?

A: Production takes 25 to 30 days following deposit receipt and artwork approval.

Q: Do you provide test samples before bulk production?

A: Yes, standard specification samples are shipped within 48 hours via DHL/FedEx freight collect.

Q: What payment terms do you accept for initial orders?

A: T/T 30% deposit with the remaining balance paid against copy of the Bill of Lading, or L/C at sight for qualifying volume distributors.
