For the purpose of cleaning cementitious grout acidic based tile and grout cleaners are extremely effective. By reacting with the cement in the grout, it removes the dirt present in it. It also removes a small top layer of the grout to expose the lower clean layer. Acidic based grout cleaners are particularly effective at cleaning and whitening white grouts that have stubborn stains on them. They are also very aggressive in removing soap scum and hard water deposits in ceramic and porcelain tile showers.
Acidic cleaners should not be used on marbles. Marble is made up of calcium carbonate (CaCO3), which is highly reactive to even mild acids. When marble encounters an acidic agent, the acid dissolves parts of the marble surface exposing marble that was once below the surface. This newly exposed marble is unpolished, unlike its surroundings. Consequently, these etch marks show up as dull whitish marks compared to its nice polished surroundings.
