Tackle the toughest job-site mess with ease! Mapei UltraCare Keranet is a high-performance, acid-based concentrated cleaner that makes short work of cement residues, grout haze, and construction grime. This 5-liter professional size is designed for those who need maximum cleaning power and efficiency for large areas.

Unlike standard household cleaners, Keranet is a heavy-duty industrial formula. Whether you are dealing with "white salt stains" (efflorescence) on your brickwork, limescale buildup in wet areas, or stubborn rust marks on your patio, this product dissolves them quickly and effectively.

Because it’s a concentrate, you control the strength. Dilute it with water to suit the level of dirt—making it one of the most cost-effective solutions for large floor installations and exterior facade cleaning.

• HEAVY-DUTY CLEANING POWER: Professional-grade concentrated acid cleaner specifically designed to remove stubborn cement residues, grout haze, and installation dirt from all acid-resistant surfaces.
• MAXIMUM VALUE (5L CONCENTRATE): Highly concentrated formula that can be diluted with water (up to 1:10) for massive coverage. One 5-liter bottle is perfect for large-scale projects and deep cleaning tasks.
• VERSATILE STAIN REMOVER: Effectively eliminates salt efflorescence (white stains), limescale, and even tough rust stains from porcelain, ceramic, terracotta, and natural stone.
• INDOOR & OUTDOOR USE: Perfect for cleaning newly installed floors, building facades, and patios. Ideal for "post-construction" cleaning to make your surfaces look pristine.
• SAFE FOR GROUT JOINTS: Advanced formula targets residues and stains without damaging or corroding the cementitious grout joints when used according to instructions.
