Cleaning old floor tile grout

[easyt]

I have a 20 year old ceramic tiled sitting room floor that is grouted with a powdered mixed grout. It was light grey but now is dark grey. I wondered about cleaning it. Any tips?

I have enough projects to keep me busy for a while but thought it might give me something to do in the winter whilst OH knits and watches TV. :lol:

Go on Tradetiler.com or .uk and go on the Aquamix products. You could use the grout colourant that will change the colour of the grout and also seal it at the same time. You will need to use phosporic acid (also sold at Tradetiler) to clean the grout first.

Or try LTP Grimex from any Tile giant store or Tile Giant online or direct from LTP online...
