cleaning quarry tiles?

[lcjohno]

hi all, i've recently moved into my new house which has a red quarry tiled floor in the kitchen and dining room. I really want to give the tiles a good clean because they look a bit dirty, especially the grout lines. Can anyone advise me on the correct products to use and the best method for cleaning, cheers for any advice.

LTP grimex is good... and depending upon quarry make ..might not need sealing..
