How do you apply this product to clean grout?

Post Installation Cleaning: First, wet the surface, then use DETERDEK diluted at a ratio of 1:5 or 1:10 (1 QT of product in 1.5 GAL of water). Apply the solution a few square feet at a time; wait a few minutes and then rub vigorously with an abrasive scotch pad or large brush. Remove all residues using a cloth or wet vac and rinse with plenty of water. Should any stubborn dirt remain, repeat the application with a more concentrated solution. For outdoor cleaning of surfaces showing signs of aging (smog, dust, etc.): dilute 1:10 (1 QT per 2.5 GAL of water). Then follow the same application methods described above. Caution: do not use on marble, limestone, travertine or any acid- sensitive materials. Before applying the product, we recommend testing on a small area of the surface. Please call if you have any other question. SEALERS R US

Thin set (unmodified) created haze on shower floor penny tile; Will this product remove haze without degrading thin set beneath penny tile?

Good morning, we do not understand what you means as "this set" and "penny tiles". In case you have to remove cement grout residues (if you mean this for "haze") and the tiles are in porcelain, ceramic, cotto or stones risistant to acidic detergents you can use DETERDEK. Kind Regards.
