The Square Scrub Doodle Scrub EBG-9 3D Scrub Pad (Blue, Tile & Grout) targets the biofilm that builds up in grout lines, low spots, and textured surfaces like LVT, where detergent, water, and soil collect during cleaning. That buildup is difficult to remove with a standard pad and can harbor odor-causing residue. This 3D-textured pad breaks it up more effectively. Sized 4.75 x 10 in., sold each.
