Porcelain tiles

[foodluva]

I have just laid porcelain tiles on my kitchen floor which have a high sheen. I am still in the process of cleaning adhesive/grout etc off them but have noticed that they are not as highly polished as they were before laying. I'm not sure if they still have residue on them but wondered if anyone had any tips on the best way to clean and shine porcelain tiles? I was recently given a fantastic tip on how to clean stainless steel (baby oil!!!!) and wondered if there was a similar one for highly polished floor tiles?
