i have slate tiles through hall and kitchen.they look nice but keeping them clean drives me mad.i tend to hoover up or use dustpan and brush (dd sacred of dyson) and then wash floor with cloth.time all this takes means it does not get done v often.mops must be better?my tiles have bumpy surface so not sure what is best method.am tempted by those static cloth ones and another sort to wash.is there somebody out there more organised and houseproud than me who can help make my kitchen floor happy again please?!
