Dampen a clean rag with white vinegar. Your rag should be wet through with white vinegar, but excess vinegar should not drip or seep from the rag. Either pour vinegar onto your rag in a sink or dunk your rag in vinegar in a bucket. Wring out the rag lightly over a sink. Too much white vinegar can cause this liquid to spread to areas of the marble tiles that are already clean.

Although this can be wiped away easily, wringing out your rag after wetting it can prevent extra work. Vinegar is a great option for removing hard water stains or built up soap scum. Drape the wet rag on top of stains or buildup. Place the vinegar dampened rag over the buildup or stain on your cultured marble tiles.

Make sure the rag is flat against the stain and the wet parts of the rag touch it. Allow the rag to remain on top of the buildup or stain for several hours. With especially light buildup or stains, you may be able to wipe these away in one swipe with your vinegar dampened rag. Rinse the treated area with cold water. Remove the vinegar dampened rag from the afflicted area of your marble tiles.

Pour cold water from your sink into a cup or small bucket. Use this to douse the treated area of your marble tiles. Wipe up excess liquid with a clean, soft, dry rag. Hot water in some cases can cause stains to stick to surfaces more stubbornly. Using cold water will prevent this from happening. Treat remaining stains or buildup with a cleaning agent.

Select a cleaning agent that is intended for marble tiles or similar stone. This product should not have abrasives, which can scratch or compromise the finish of your marble tiles. Follow the label directions on the product for best results. However, this may not be the case with all cleaners. Be sure to check the label. Polish the marble tiles with a suitable polishing agent, such as tiles wax, and a soft rag or polishing cloth to restore its luster.
