BIHUI Dual Purpose Microfiber/Hydro Grouting Sponge (XL) — Two Sides, One Fast Cleanup Big floors mean endless wringing and rinsing — and a final haze that's hard to clear without streaks. This oversized BIHUI sponge tackles both with two working faces. A hydro core absorbs water efficiently for controlled moisture management on the first pass, and a microfiber face lifts fine grout haze without scratching or leaving swirl marks on the finish pass. The extra-large size covers more area per pass with less wringing, so you clean up faster across big installs. The two-in-one sponge that handles the wash and the polish. Keep a standard hydro sponge on hand for detail work. Why Tile Pros Choose It Two faces: Hydro core for the wash, microfiber for the haze Covers more: Extra-large size means less wringing Streak-free finish: Microfiber lifts haze without swirl marks Controlled moisture: Hydro core manages water on the first pass Faster cleanup: Built for big installs Pro tip: Use the hydro side first to clean the bulk of the haze with a nearly dry sponge, then flip to the microfiber side for the final streak-free polish once the surface is almost clear.
