Terrazzo is a durable material made of marble and Portland cement, with marble chips sprinkled onto the surface. It is a beautiful material commonly found in flooring and as the base of a shower. Cleaning terrazzo floors and showers requires little work; however, care must be taken not to damage the surface. If cleaned properly, terrazzo floors and showers will maintain their beauty and last for many years to come.
Remove loose dirt and debris from the terrazzo surface. Sweep the floor or shower base with a broom prior to wet cleaning. Sweeping should be done on a regular basis, even if wet cleaning will not be done, because sand and dirt that accumulate on the surface may cause scratches.
Fill a bucket with warm water. Add 1 cup of neutral cleaner such as Rejuvenate or Miracle Sealants' Tile and Stone Cleaner. Other neutral cleaners will work as well, just as long as they are not acidic or alkaline.
Dip a microfiber cloth into the bucket of cleaning solution. Wring it out thoroughly. For a large shower base or terrazzo floor, use a microfiber mop.
Go over the entire terrazzo surface with the cleaning solution. Allow the cleaning solution to sit on the terrazzo for about five minutes. Scrub tough spots and grime with a stiff bristled scrub brush.
Dump the bucket of cleaning solution once the entire terrazzo surface has been thoroughly mopped. Rinse the bucket well and fill it with plain water. Wash out the microfiber mop or rag thoroughly, or get a clean one for rinsing the terrazzo.
Rinse the cleaning solution and dirt from the terrazzo. Use a clean microfiber cloth or mop and bucket of clear water to soak up any dirt, grime, or cleaning solution from the terrazzo. Rinse the rag or mop often to avoid transferring dirt back onto the terrazzo. Change the bucket of rinse water when it becomes dirty.
Buff the terrazzo with a clean, dry microfiber cloth. This will restore shine and absorb any excess moisture on the surface.
