Here is a step-by-step guide on how to clean terrazzo floors:

1. Remove furniture that may make cleaning difficult, especially if you have rugs.
2. Use the vacuum cleaner to suck up the dust and all the dirt accumulated on the floor. If you don’t have a vacuum, use the broom to sweep thoroughly, but carefully enough not to damage the terrazzo material.
3. Fill one part clean hot water into the bucket and mix it with one part neutral (neither acidic nor alkaline) terrazzo cleaner. Choose a neutral cleaner specifically formulated for cleaning terrazzo floors to avoid any loss of shine or permanent damage.
4. Dip the mop into the solution and wring it out until it is damp but not dripping wet.
5. Mop the floor thoroughly, starting from one corner of the room and working your way across in sections.
6. Rinse the mop frequently in the bucket of cleaning solution and wring it out each time before continuing.
7. Once you have mopped the entire floor, rinse it thoroughly with clean water to remove any remaining cleaning solution.
8. Dry the floor with a clean towel or let it air dry.
