How long will Diamond Sponge last?Updated 3 hours ago

TL;DR
With rinse-and-dry care, expect multiple weeks of use. Replace when the abrasive surface goes smooth or the sponge starts to shred.

Typical lifespan

The silica-alumina coating and high-density PU core give extended scrubbing power. Longevity depends on how rough the surface is and how firmly you press, but most users report several weeks of oven or tile scrubbing before needing a new block.

Care tips to stretch its life

1. Rinse thoroughly after every session, warm water preferred.
2. Gently squeeze out water (don’t twist or wring).
3. Air-dry completely in a cool, ventilated spot.
4. Avoid harsh chemicals or high heat, they will degrade the coating.
