Urine Stains in Grout
I was stupid and put white tile with white grout in my bathrooms. Well, to make a long story short, my 5 year old son has extremely poor aim and so now there are dark stains in the grout around the toilet. I have tried everything to get rid of the stains, including pouring straight bleach on the floor and letting it set for hours, but nothing gets rid of all the staining. Is there any way to get rid of the stains?!
