Called efflorescence, it is caused by the tiles or the mortar mineral salts that rise when exposed to water. You can use a brush and some horticultural vinegar thats stronger than the regular food vinegar. If that doesn't work you will have to get some muriatic acid to remove it, and its caustic so be sure to wear clothes that cover all your skin, goggles and chemical rubber gloves... https://www.youtube.com/results?search_query=how+to+remove+efflorescence+from+outdoor+tiles

vinegar/water mix in a spray bottle - scrub a little with plastic scrubby or soft broom...spray wash off with hose... THEN DRY with a squeegee or cloth -- apply a wax (like car wax) or use rain-x to protect in the future
