BIHUI Hydro Grouting Sponge — German Hydrofoam for Pro Cleanup Grout cleanup is where a floor is won or lost — a cheap sponge smears haze and washes out your joints. The BIHUI hydro grouting sponge is premium German hydrofoam built to do it right. It absorbs and releases water fast and evenly, removing grout haze efficiently while maintaining sharp, full grout joints — not eroding them. A dense, tear-resistant structure stands up to jobsite abuse and repeated rinsing, and it's firm enough for real cleanup work without dragging the joints. For oversized jobs, step up to the extra-large dual-purpose sponge. Why Tile Pros Choose It Even water control: German hydrofoam absorbs and releases fast Sharp joints: Removes haze without washing out grout lines Tough: Dense, tear-resistant through repeated rinsing Firm feel: Enough body for real cleanup work Pro-grade: Built for daily tile work Pro tip: Wring the sponge nearly dry and wipe in light, single passes — too much water and heavy scrubbing pull grout out of the joints. Rinse often in clean water so you're lifting haze, not redistributing it.
