Hi
My wife was recently scammed into getting the oven cleaned by a 'professional', who cleaned the oven but did not protect the floor. The consequence is that we have red quarry tiles where the near-black of the grout has been discoloured to a light grey near the oven.
Can anyone suggest what I might use to 'paint' the grout since this is the only way I can see of restoring the grout to a uniform colour.
Thanks
Paul
