I did not really measure exactly but put about an inch of bleach in the bottom of a spray container and then filled it with water. So I think it is about 1 part bleach to 8 or so parts water. I have ceramic tiles with grout between each tile and also the line where the sink meets the tile looked awful after all these years. I would not use bleach like this on fabric or anything porous such as wood. I am thinking of doing my tiled showers as well but have a tinted grout there so I will wait til I can go to the store and stay there as long as I want without virus worry and find some bleach okay for colors. If you have a different counter top you can try a little bleach water in an inconspicuous space and see how it works. Someone on here recommended 1 part bleach to 20 parts water (5%) for killing viruses but I decided some more bleach would not ruin my tiled surfaces.
