I keep getting mold in my shower grout. I redid some of the bad spots

Room needs more or better ventilation. Clean mold with vinegar, it will kill the spores. Even a portable fan will help.

Once you eliminate the mold with vinegar (you can make a paste of vinegar and baking soda so the vinegar will not run down the wall), you wipe down the tiles after each shower. Use a squeegee or a towel. That will cut down on the moisture in addition to better ventilation and the use of a fan. Good luck!

If you use a shower curtain or a glass door, leave it open so the stall can dry completely.

You will have to use some fluid to clean this. It is in a yellow bottle, and it has 3 letters to its name. You can find it at a hardware store, or Lowe's or WM. I forgot what the 3 letters are, but it is very good. I am sorry that I can't name them, but this is all I can help you with. Best wishes, J.

It is something like B S W, so look for that, in the yellow container. Best wishes, J.

Besides ventilation, here is a good mold remover to use. https://www.hometalk.com/diy/clean/bathroom/the-best-way-to-remove-mold-mildew-with-2-ingredients-no-bleach-33077514.....after every shower spray it with a dailey etc shower spray, this will keep the mold in check

Remove all grout sealer and recaulk, for health and safety. Mold is very serious, it is a silent killer.
