porcelain floor tiles

[terence7556]

we have recently laid some black porcelain floor tiles in our kitchen. they are textured like bark, (whether this is a good idea is a bit late now so we are stuck with them.)we wondered about sealing them to keep them clean or just if any ABers had any tips to treat them.
oddly one thing that has worked well is mopping them with a product by Astonish called no rinse wood floor cleaner for veneer or laminate floors, this brings the tiles up a treat untill the granchildren visit but its a small price to pay
thanks in advance for any advice useful or otherwise
