About This Product
Heavy-Duty Cleaner for Terracotta and Masonry Surfaces
HMK® R165 Terracotta Cleaner is a heavy-duty, acid-based concentrated cleaner formulated to remove grout residue, cement residue, construction dirt, persistent lime deposits, calcium deposits, and efflorescence. It is designed for cleaning unglazed terracotta, clay tiles, brick, block paving, unglazed ceramic and porcelain tiles, concrete blocks, and acid-tolerant natural and artificial stone.
Removes Construction Residue and Mineral Deposits
The concentrated formula restores surfaces affected by post-installation residue and mineral buildup while special inhibitors help control oxidation of vanadium salts, manganese, pyrite, and other metallic deposits commonly found in clay tiles and bricks. Suitable for both interior and exterior applications.
Application and Surface Limitations
Do not apply in direct sunlight or on acid-sensitive materials such as polished or finely honed marble, limestone, metals, or plastics. For lighter construction dirt where an acid cleaner is not required, HMK® recommends HMK® R155 Intensive Cleaner as an acid-free alternative.
