HG Tile Power Cleaner (Polish, Wax & Dirt Remover)
Dissolve half a litre in half a bucket (5 l) of lukewarm water and apply generously with a floor cloth or mop. Do not treat more than 10 to 15 m2 at once. Leave to work for at least 5 to 10 minutes. Now remove the solution from the surface using a mop. Finally, mop the floor again with clean water. 1 litre is enough for 20-40 square metres of floor area, depending on how dirty the floor is.
