Yep.
About a 3 to 1 mix (water to hypo) is what i would use. Obviously use the PPE, watch the splashes in your face etc.. Cover any plants/grass/flowers under the tiles and watch run-off into garden areas.
Be very careful with pressure. These tiles are brittle and can break/drop/loosen very easily.
Hypo, dwell, low pressure rinse is what i would do.
