I have a quick question about using bleach for green algae in grout about the water line. If you have a colored grout (ours is grey), will the bleach affect the color of the grout? My first instinct is to use bleach, but then I am also worried about it bleaching out the color of the grout. Anyone have any experience with this?

You will only need a diluted bleach solution to kill the algae and it should not effect the color of your grout color. That said mix a couple table spoons of bleach in a quart of water into a hand sprayer and test it on a small out of the way spot.

Anyone ever try using Tilex to clean them? I know it works better than bleach in the bathroom. Might sound silly, but just an idea.
