Mildew on walls in Bathroom

Did you install a fan? What you have is a ventilation problem, and while the vents may help, where they vent to? If they do not vent to outside they could be spreading the problem instead of fixing it. Even a small tabletop fan will help until you can get the problem fixed. If there is a window in the bathroom open it for a good half hour after shower use. A dehumidifier will help too. I would enlist the assistance of a mold specialist and contractor as they will tell you where to direct the vents and what type type of fan to install or anything else that may be needed to solve the problem. Good luck!

Good Morning Toni, I wonder if you have a DEhumidifier going in the house (especially near the bathroom area)? That will help immensely in cutting down on the humidity level. Are you turning ON your new bathroom vent about 10-15 minutes BEFORE you use the shower or tub, AND are you LEAVING IT ON DURING your bath or shower AND for at least 20 minutes AFTER you are finished? This also will help alot (I know some folks who only turn it on during their shower, and while that helps a bit, there is plenty of residual moisture to be pulled out from natural moisture in the air and evaporation of droplets from sink and toilet activities). Have you checked to make sure there are no water leaks or dripping in the attic area where many pipes are located and can collect evaporative droplets that make their way into insulation and/or the space between walls. By the way, do you have a carpeted hallway? If so, check under the edges of it, or wherever you may see any discolored spotting; it might be mildew or mold.

GOOD LUCK and thanks for using Hometalk.

She said she had a vent installed.

I am assuming since it's a bathroom vent, it has a fan to exhaust the moisture. I'd make sure the vent fan was not installed upside down first. That did happen to me - duh.

Thank you for all the help. The vent does have a fan and I keep it on during my shower and for about an hour afterwards also. Added the damp-rid and also, which I forgot to mention, I put a fan inside the doorway of the living room and hall. So this fan blows pretty much all the time now. Only started that about a week and a half ago. Not sure if that is helping yet. Thanks again!!

First, remove the mildew with dawn dish detergent, bleach and water mixture. Then rinse and allow to dry. Pour bleach in a small bowl or pour bleach into a sprayer (protect yourself using a fan and goggles) then use a tooth brush to apply the bleach. You might have to redo this as I'm not sure what walls you're speaking of.

If it's the bath room tiles, I treated mine with the same mixture, allowed it to dry, applied pure bleach to all of my grout then I sealed it! Never had the problem repeat.

I clean my bathroom walls (shower walls) with a sprayer filled with equal amounts of white vinegar and blue (original) dawn dish detergent. Be sure to apply this to your entire bath area when no one will use the shower for at least an hour and a half. Spray entire shower area, walls, stainless steel fixtures, bathtub, glass doors and shower head. Let it sit for an hour then get a brush and brush away (no elbow grease needed, dirt comes off like butter) then rinse. You'll notice your fixture looks new, scuff marks and dirt comes right off and so is hard water deposits. Be sure you're careful because this mixture makes your tub very slippery. I keep a sprayer of this mixture in my bathroom. It's cheap and it works!
