I have a mold problem with the grout in my shower. Have tried many varieties of cleaners and mold killers with little to no success.
Initially when it got bad 3 or 4 years ago, I thought the previous homeowners had just caulked the corners and went in and removed all the grout, regrouted it, and sealed it. Before we had the cleaning service, my wife was able to keep it clean and no issues. Well we got slack with the cleaning service so it is back. Any suggestions on what works to get it out of the corners and where the floor meets the walls short of stripping it all out?
