Slate flooring can be a beautiful addition to any home, but it is not always the easiest material to maintain. It might seem like the perfect solution to hiring a professional, but that can get expensive.
This comprehensive guide will teach you how to clean slate tile flooring so that they will continue looking new for years to come.
What Is Slate Flooring?

Slate is a type of metamorphic rock made up of clay, silt, and other minerals. It is quarried in various parts of the world and comes in multiple colors, including black, green, red, purple, and white.
One of the main benefits of slate flooring is its natural material. This means that it is non-toxic and will not release harmful chemicals into the air as some manufactured materials can.
Slate is also very durable and slip-resistant, making it a good choice for high-traffic areas.
Additionally, it is resistant to stains and moisture, so it is a good option for homes with pets or children. And unlike some other types of flooring, slate is relatively affordable.
How to Clean Slate Tile Flooring
Slate tile floors are a beautiful, natural option for your home. But like all types of flooring, it requires regular cleaning and maintenance to keep it looking its best. Here’s an easy, 5-step guide for effective slate floor cleaning.
Step 1: Sweep or Vacuum Your Slate Floor
It is vital to remove all loose dirt and debris from your slate floors before mopping them and apply any cleaning solution. Doing so will help prevent scratching the tile’s surface.
When cleaning slate floors, remember that they can be scratched easily. Hence, use a vacuum cleaner with a non-abrasive attachment or a soft-bristled room. Try to reach between the slate tiles to remove all the dirt.
Step 2: Mix Warm Water and a Mild Detergent
If your floor appears dirty or stained, mix a mild detergent with warm water in a bucket before mopping the slate tiles. A mild-dish soap or laundry detergent will be great for cleaning slate floors.
Never use any harsh chemicals on your slate tile floors, as the ensuing chemical reaction might damage the tile’s surface.
If you must use a commercial slate cleaner, make sure it’s a natural PH product, as acidic cleaners can damage natural stone flooring. Please read the product label on how to use it before applying.
Step 3: Mop and Rinse Your Slate Floors
Dip your mop in the soapy water and wring out most of the liquid until the mop is damp but not wet. Then start mopping your entire floor from one corner to another, using gentle back-and-forth motions. The smooth strokes will help prevent scratching your slate floors.
If needed, make a second batch of cleaning solutions. You can also use a steam mop for optimal results. Steam mopping will give your slate floors a deeper cleaner, so consider doing it from time to time.
Once done, remember to rinse off the soap with a clean mop dipped in warm water.
Step 4: Dry the Slate Floors Thoroughly
Slate floor tiles have a porous surface. Hence, you should wipe off any excess water. You don’t want the standing water to get into the pores in the slate tiles and grout.
Use a soft cloth or towel to absorb most water before allowing the flooring to air dry. Ensure your slate floors have dried thoroughly before walking on them again.
Step 5: Apply Teak Oil
Once your slate floors are completely dry, finish it off using slate oil to bring out its natural shine. If you don’t have slate oil, use teak oil instead.
Apply a thin layer of oil onto the natural slate tiles to enhance their natural beauty. Don’t apply too much since you don’t want to make your floors slippery.

Next, gently scrub with a soft-bristled brush. This will help lift the stain without damaging the textured surface of natural stone flooring.
