High-Density PU Coating Sponge, Surface-Safe and Extended Service Life, Durable Sponge
Product Overview
In kitchen cleaning and daily household chores, conventional sponges with low density (18-25D) often lose elasticity and absorbency quickly, requiring frequent replacement. Our High-Density PU Coating Sponge features a 45-47D high-density PU coating process that structurally reinforces the sponge base, maintaining its original shape even after repeated compression.
The coated surface is dense and smooth, ensuring gentle contact with various surfaces. Testing confirms it will not scratch or damage sensitive surfaces including stainless steel, ceramics, glass, or non-stick coatings.
With a service life of approximately three weeks—about three times longer than conventional sponges—this product is ideal for home kitchen cleaning, restaurant back-of-house use, and hotel housekeeping, balancing surface safety with cost-effectiveness.

Usage Tips
Plan replacement timing wisely: Assess replacement based on usage frequency and soiling degree. While offering longer service life, cleaning efficiency naturally declines over time. Replace when you notice slower water absorption or visible surface wear.
Better results with cleaning agents: The fine pore structure effectively retains water and cleaning solution. Use neutral or mildly alkaline cleaning agents, avoiding strong acids or alkalis that may cause chemical erosion.
Rinse and air-dry after each use: Rinse with clean water, squeeze out excess moisture, and place in a ventilated area to air dry naturally. Avoid prolonged soaking or damp storage to extend service life.
Separate sponges for different cleaning areas: Keep kitchen and bathroom sponges separate to avoid cross-contamination. The coated surface resists particle entrapment but different areas should use distinct tools.
Frequently Asked Questions
Q: How was the three-week service life calculated?
A: The three-week service life is based on laboratory accelerated testing simulating typical daily household usage (1-2 uses per day). Conventional sponges showed significant performance degradation after about one week, while this product maintained good absorbency and structural integrity for three weeks due to the high-density PU coating protection. Actual service life may vary based on usage frequency and maintenance practices.
Q: Does "surface-safe" apply to all materials?
A: This product has been tested and verified for common kitchen and bathroom surfaces including stainless steel, ceramics, glass, non-stick coatings, and quartz. For extremely sensitive surfaces (such as high-gloss painted finishes or mirror-polished metals), we recommend testing on a small, inconspicuous area first.
Q: Can this sponge be used to clean non-stick pans?
A: Yes. The PU coating surface is smooth and fine, containing no abrasive particles. Normal wiping on non-stick pan surfaces will not damage the coating.
