Helen Harrison, home economist and former member of the Good Housekeeping Institute, says: 'Without knowing the exact composition of your tiles and what they may or may not be sealed with, it's difficult to give precise instructions, but here are some general guidelines.

Firstly, test on a small, inconspicuous area to check the method won't cause damage or discolouration. Begin by giving the entire floor a good clean to remove surface dirt and dust. Vacuum or sweep, then use a warm, weak solution of water and washing-up liquid to mop the tiles.

If a proprietary product was recommended when the tiles were first installed, use that to clean the floor, following the manufacturer's instructions. For light discolouration, dip a toothbrush into a solution of one-part water to one-part bleach and use it to scrub along the grout. Leave for a few minutes and then rinse with water.

For heavier staining, make a stiff paste of bicarbonate of soda and distilled white vinegar. Dip a toothbrush into it and scrub the grout. Leave for 10 minutes and then rinse with water. If this fails, try a specialist product such as Grout Rescue – Colour & Seal.
