How to Clean Natural Slate tiles ?

[G1nzo]

Whole floor in Kitchen is Slate Tiles
300 x 300 from Wickes i think
They are natural finish with Lines and ridges which is fine
Had a Wall taken fown and door blocked up during recent works
Now the Tiles are covered in Plaster and dust
tried washing them down but the dust stays on the lines and in the
imperfections of the tile
How can i clean this out Also Some Danish oil has been splashed on the tiles near the doors
Cant get this off either
Anyone any ideas ??

Hi, what you could try doing is brush the area with a soft brush (paint brush is ideal) to remove any loose dust and plaster.

Once that is all up, it may be worth using a tile cleaning product to remove the rest. One that I have used in the past which worked really well is made by Lithofin and is a Power Cleaner.

If you decide to use cleaning materials make sure you follow the instructions to the letter to ensure that you get the result you want. If you click on the link there is a technical guide with directions for use and how to dilute the concentrate etc.

What about the grouting? Has that been effected too??
