High-Density PU Coating, Strong Water Absorption, Non-Scratch Surface, Durable Sponge

High-Density PU Coating, Strong Water Absorption, Non-Scratch Surface, Durable Sponge

1.Product Overview

In daily cleaning, sponge water absorption speed directly determines wiping efficiency. Slow-absorbing sponges require repeated dipping, extending cleaning time, while difficult-to-squeeze-dry sponges leave water marks on surfaces, compromising results. Many sponges also tend to leave fine scratches on dishes or stovetop surfaces during wiping, leading to wear on cookware coatings and diminished countertop gloss.

The High-Density PU Coating, Strong Water Absorption, Non-Scratch Surface, Durable Sponge has been specifically designed to address these three issues. The high-density PU coating (45-47D) creates a finer, more uniform pore structure in the sponge base, allowing water and cleaning solution to be quickly absorbed upon contact and evenly distributed across the wiping surface.

The coating surface is smooth and fine, containing no abrasive ingredients, ensuring no scratches or loss of gloss when wiping stainless steel, ceramics, glass, or non-stick coatings. The high-density base material provides excellent structural stability, maintaining its original shape even after repeated squeezing without collapsing or deforming.

Ideal for home kitchen cleaning, dishwashing, and hotel housekeeping—scenarios demanding high water absorption efficiency and surface protection.

3.Usage Tips

Fully soak before first use: For new sponges, fully immerse in clean water and squeeze dry before first use. This activates capillary absorption channels, ensuring stable and uniform absorption speed.
Adjust water amount according to stain type: For light stains, use in semi-dry state. For heavy grease or burnt residues, fully wet the sponge with cleaning agent to soften grime before lifting away.
Squeeze to rinse after each use: Rinse with clean water and squeeze repeatedly under running water until water runs clear. Avoid twisting or rubbing vigorously to preserve internal pore structure.
Separate uses by area: Keep dishwashing sponges separate from heavy-grease area sponges to prevent cross-contamination and extend service life.

4.Frequently Asked Questions

Q: How are strong water absorption and a non-scratch surface achieved simultaneously?

A: Water absorption depends on the pore structure and density of the sponge base material—high-density pores create stronger capillary effect. The non-scratch surface depends on the physical properties of the coating surface—the smooth, fine PU coating contains no abrasive particles. The two are well integrated through high-density base material and PU coating combination.

Q: What is the difference in water absorption speed between this sponge and conventional sponges?

A: Conventional sponges (18-25D) have larger pores and looser structure, resulting in slower absorption with water trapped inside. This product's high-density base material (45-47D) features finer pores and more absorption channels per unit volume, providing superior absorption speed and release uniformity.

Q: Will the coating surface become rough or shed lint after prolonged use?

A: No. The PU coating maintains structural stability and will not develop burrs or shed debris. With extended use, the coating surface becomes smoother through normal physical wear. When obvious polishing or significant absorption decline occurs, replacement may be considered.

Q: What types of cleaning agents are suitable for use with this sponge?

A: Suitable for neutral or mildly alkaline cleaning agents like dish soap and kitchen degreasers. Not recommended for strong acid or strong alkali cleaners (toilet bowl cleaners, heavy-duty descalers) as they may cause chemical corrosion to the PU coating surface.
