Limestone is a sedimentary stone that is more porous than most other stones. It is at the opposite end of granite in terms of hardness. Like marble, limestone is rich in calcium. It is formed from the accumulation of finely eroded rock particles that is cemented together by calcium and other types of minerals. Usually, limestone has a honed or matte finish (versus a polished marble) and rougher in surface texture. These stones are known for their inherent variations in color, texture (surface) and finish. Depending upon wear, location, type, and care, limestone will need professional maintenance every 1 – 3 years.
Depending on the type of limestone, care must be taken during cleaning. Thorough vacuuming and mopping with clean water and neutral pH soap inhibit dirt and soil build-up. Every few months, bleach can be used to keep these more textured stones (even sanded grout) cleaner, and lighter and brighter in appearance.
- All limestone should be sealed.
- Neutral pH stone soap is best even for daily cleaning.
- White, plain bleach can be used on heavier soils and greasy film.
- Always test cleaners in an inconspicuous area and be sure to follow directions.
- Floor mats, especially those made of natural fibers, will reduce scratches.
- Use vaccums with soft brush attachments to remove dirt and debris prior to mopping.
- If not cared for properly, the surface can look dark and dingy from dirt and soil accumulation. Limestone must be sealed and sometimes requires extra applications due to porosity.
