I have a small section of stained grout that I can't seem to clean no matter what. I have tried uploading pictures, but I can't figure that out either, I'll try to describe as best as possible. I am a decent DIY'r, but this has be stumped.
The grout is on some wall tile in the kitchen, above the stove. The section that is stained is about a 5" vertical section, beginning from the very top. There is not a border tile on the top, the grout just goes up to the bottom of my kitchen cabinets.
The grout is a light sand color. The stained has turned much darker.
I have tried baking soda and vinegar, lemon juice, and some Tile Guard brand grout cleaner. I have tried rubbing it on, rubbing it in, scrubbing it in, spraying it on and taping it to keep it wet, and all with no success.
I will try to get some pics up soon.
Thank you for taking the time to read and reply.
