About This Product
Acid-Based Cleaner for Concrete, Masonry and Tile
Miracle SealantsĀ® Phosphoric Acid Cleaner is a fast-acting acid-based cleaner formulated to remove cement grout haze, mortar residue, joint cement, lime deposits, hard water buildup, efflorescence, rust, dirt, and grime from concrete, masonry, grout, tile, and selected natural stone surfaces. Its phosphoric acid formula provides effective cleaning while offering a milder alternative to stronger acid-based cleaners.
Compatible with a Wide Range of Surfaces
The cleaner is suitable for pre-cast concrete pavers, concrete, masonry, sanded grout, porcelain tile, quarry tile, unglazed ceramic tile, cast stone, swimming pool slides, fountains, and selected flamed, honed, or tumbled natural stone surfaces including granite, slate, limestone, and marble. It is designed for both interior and exterior applications.
Removes Common Construction and Mineral Deposits
Phosphoric Acid Cleaner effectively removes cement grout haze left after tile installation, mortar residue, lime and hard water deposits, rust stains, and efflorescence. Its fast-acting formula helps restore the appearance of hard surfaces before sealing or routine maintenance.
Surface Limitations
