Rough slate tiles add natural texture and character to homes, but their porous surface needs mindful cleaning to prevent dullness and staining. This guide explains a practical, step-by-step approach using safe cleaners and common tools to keep slate floors looking vibrant without damaging the stone.
By following practical methods and selecting slate-safe products, homeowners can maintain the beauty of rough slate floors while minimizing wear over time.
Quick Answer
Use a pH neutral slate floor cleaner with a microfiber mop for slate floors, paired with a slate floor cleaner brush for grout lines. Avoid harsh, acidic, or abrasive cleaners. For stubborn grime, a steam cleaner for slate floors can help, but test on a hidden area first to ensure no surface damage.
What You’ll Need
- pH neutral slate floor cleaner
- Microfiber mop for slate floors
- Slate floor cleaner brush
- Slate tile grout cleaning brush
- Steam cleaner for slate floors
Before You Start
Prepare the room by removing furniture and rugs. Sweep or vacuum to remove loose grit that can scratch rough slate. Work in small sections and avoid saturating the stone; slate is porous and excessive moisture can lead to water spots or mortar staining. Wear protective gloves and ensure good ventilation when using cleaners. Plan for a 20–40 minute cleaning session per area, depending on size and grout depth.
Step-By-Step: How To Clean Rough Slate Floor Tiles
- Clear the space and vacuum or sweep, removing loose dust and grit.
- Mix a small amount of pH neutral slate floor cleaner with warm water according to directions.
- Dip the microfiber mop for slate floors into the solution and wring well to avoid pooling.
- Begin at a corner and mop in straight lines, keeping the surface damp but not soaked.
- For grout lines, apply a thin amount of cleaner and scrub with the slate tile grout cleaning brush.
- Rinse the mop frequently to prevent spreading dirt; re-wet as needed and mop again to remove soap residues.
- If stains persist, use the slate floor cleaner brush to target the area with a gentle circular motion.
- Allow the floor to air-dry fully. Open windows or use a fan if the room remains damp.
- Check for missed spots and re-clean those areas with the same method.
- For heavy grime or greasy spots, consider a trial run with a steam cleaner for slate floors on a low setting, avoiding prolonged steam exposure.
- Inspect grout lines after drying; reseal if grout appears dull or porous, following manufacturer guidance.
- Return furniture and textiles once the floor is completely dry.
