Me and my wife bought an older home 2 years ago. We looked at many homes before buying this one and never found one for a price we thought was fair. We found this home at a reasonable price, not too high and not too low. We purchased the home. About a little over a year after living here we noticed black mold growing on our bathroom ceiling. I took a scrubber and bleach and cleaned the ceiling. The mold was gone for several months. A few weeks ago the mold came back. It came back fast and came back a lot more than the first time. I researched a little on line and found out I probably should not have used bleach the first time. It said that it will initially remove the outer mold and make it look like it is gone but it wont kill it and creates a bigger feeding ground because it traps moisture in the pores of the ceiling which moisture is what feeds the mold. From what I read it appeared that vinegar was one of the best things you could use to kill it. I used Vinegar this time and it cleaned it up pretty good, however it appears to be showing up again. I do not know if I should have the bathroom completely gutted and finished in tile, or if I should clean it real good again and if there is some kind of sealer or something I could put on it to help. I probably need to get a newer vent fan to keep the humidity down, but what other things can I try to help with this. Any of you ever dealt with this and what did you do to fix it?
