Sweep the floor tiles, making sure there's no residual dust and dirt sitting on the surface.
Add the tile cleaner to your bucket with the water as per the instructions. Apply and then leave to sit for 1–2 minutes.
Mop with clean water to rinse thoroughly. Allow to dry naturally or use a cloth to wipe your tiles dry to prevent streaks.
For stubborn grime, apply again, leave for 3–5 minutes. If required, scrub at the grout using a tile-suitable scourer, then rinse thoroughly again with a mop.
