HMK R165 Terra Cotta Tile Cleaner.
A heavy duty, fast-acting, dilute acid type cleaner for unglazed terra cotta, Mexican pavers, quarry tile, and brick pavers. HMK® R65 thoroughly removes dirt, grout/cement residue, lime deposit, efflorescence, and rust from all unglazed surfaces. Special inhibitors control oxidation of vanadium salts, manganese, pyrite and other metallic deposits commonly found in clay tile and brick. Avoid contact with metal; acid/fumes will cause etching.
Protect all adjacent non-masonry surfaces. Do a manageable area at a time. Thoroughly wet area to be cleaned. Apply R65 full strength or diluted 1:3 - 1:10 with water depending on situation. Immediately scrub with stiff bristle brush or white/tan polyester pad, quickly rinsing with water until solution is completely removed.
After the application process is completed, clean the area thoroughly, using HMK® R155 Intensive Cleaner -acid free- diluted approx. 1:10 with clean water. Afterwards, rinse the area thoroughly with clean water. Repeat the cleaning procedure in the case of very strong contamination.
For the removal of light construction dirt use HMK® R155 Intensive Cleaner/Grout Film Remover.
