Hi Creighton, I would recommend to use a Numatic multi-mop with a multi-mop microcleaning power pad to deep clean your clients kitchen tiles, if the grout lines need to be deep cleaned just scrub them with a grout cleaning brush, after the tiles and grouting have been deep cleaned i would recommend to use a flat mop with waffle microfiber floors cloths to absorb all the loosened soils. This concept will give you perfect results and if you need any further information, please just let me know.
Kind regards
Tadgh
