Tiles and Lithofin KF Products

[carlyai]

We have Rectified Glazed Ceramic floor tiles outside. They are like a stone finish surface.

The tile box also says: Dynasty Tiletop and product standard: MS ISO 1300:203, TIS 250B -255, and other numbers that I don't have a clue mean.

How can I tell if they are grade A, B, or C, as I can't see it on the packet?

Also, they seem to get dirty, and water spills show, even though I have read that you don't need to seal ceramic glazed tiles.

There is mention (on the web) products for cleaning ceramic glazed tiles: Lithofin KF Conditioning Cleaner, Lithofin, KF Intensive Cleaner, Lithofin KF Grout Protector, and Lithofin KF Cement Residue Remover.

Any one know where I can get these products, or similar in Thailand?

Also how do you clean paint spills from the tiles?
