HMK® R75
Exterior Stone Cleaner
ACID BASE
For Professional Use Only

APPLICATION:
An acid type cleaner for exterior use on all rough/textured, and honed stones, especially granites with high iron content (blocks rusting process). For interiors, and when fumes are a concern, use the milder HMK® R69 Interior Stone Cleaner on granites and other acid resistant materials. HMK® R75 thoroughly removes decade-old dirt, grout/cement residue, lime and calcium deposits, and prevents rusting. Do not use on polished surfaces. Avoid contact with metal; acid/fumes will cause etching.

DIRECTIONS:
Always mix solution where spills can do no damage. Protect all adjacent non-masonry surfaces. Do a manageable area at a time. Thoroughly wet area to be cleaned. Apply R75 diluted 1:3- 1:10 depending on dirt and acid resistance of the stone/grout joint. Scrub lightly with brush to remove dirt. First rinse should be a flood rinse. Second rinse should be a neutralizing rinse using a solution of HMK® R55 Intensive Cleaner (or a pH 8-9 alkali solution) and water.
