Here are some more tips for cleaning marble floors: Use a soft broom or a dry mop to sweep all the dust and dirt particles from the marble floor. Make sure you get rid of all the visible dirt particles especially at the corners of the room. Use a damp mop to clean the floor eliminating all the light stains and the dirt that the broom missed. Make sure that the mop is damp but not wet, as the porous surface tends to soak up or absorb water. Use warm water and squeeze the mop carefully to get rid of all the excess water before using it. Use a terrycloth mop or paper towels to dry the floor and to get rid of all the excess water. Inspect the dry floor to see if there are any stains that the mop may have missed. Remove the stains using a sponge dipped in warm water with a few drops of dishwashing liquid. Scrub the stain off, then wipe, and dry the area. Mop the floor once more using pH neutral floor cleaner and warm water. This will help to get rid of all tough stains and any remaining dirt. Make sure you use a damp mop, not a wet one. Rinse the floor with plain water and dry it as soon as you finish. Use a polish or wax to protect the floor and keep it shiny. Use a soft clean cloth to apply the wax and buff the floor, working in small circles, until you complete the entire area. Use a clean cloth to wipe away any excess wax. Leaving excess wax on the floor can cause accidents as the floor becomes very slippery. If you spill anything on the marble floor, you should clean and dry the area immediately. Acidic stains like those caused by liquids like citrus juices, wine, tomato sauce and others can permanently stain the floor. If the floor stains, you should get the services of a professional who can get the stains out. Do not try to use coarse cleaning materials like steel wool, or acidic cleaning solutions, to clean the marble floor. These products can permanently damage the floor surface. If you have a large marble floor surface, you should use a cleaning service in order to get the best results. The professionals are able to carry out the cleaning faster and they have all the professional cleaning products that are necessary. They will also get rid of any stains more easily. Remember to get the floor sealed and buffed at least once a year to keep it shiny and looking new!
