Question DetailsAsked on 9/8/2011

I'm seeing dark spots on the walls above my shower, and I assume it's mold. What is the best kit for testing it, and best way to remove it?

The spots are dark brown (perhaps black), and small. I've wiped them clean once before, and they've returned (thus I assume it's mold). There are about 10 small spots.

In addition to the test kit, what are some general preventative measures to limit the formation of mold in shower areas?

mold is a very bad thing, if it gets started behind the sheetrock you need to have it removed. then treat the lumber that may be contaminated. a spot cleaning would to use bleach then paint with either kiltz or 123 bens I have used both they both have a primer mix that addresses mold issues. it is best to have a contracter take a look at it to be sure it is only on the surface.

I would not bother testing it - undoubtedly mold or mildew - same diff. Usually starts up near the ceiling, in the back corner of shower/tub enclosure, and along exteriro walls in the winter, where moisture condenses on the colder wall.

Clean well by scrubbing with TSP and washing off, then wash well with 50% chlorine bleach and water (regular laundry bleach like Purex), holding the wet rag on the general area where the spots were for about a minute, then wash off with fresh water.

If the spot is damaged (not smooth paint) then apply Kilz paint, followed by your finish color paint with a mildewcide powder mixed in per instructions (available where you by paint). Most household interior paints do NOT have mildewcide in them, so they pick up mildew quickly.

Prevention - washing walls down with a capful of bleach per gallon of water and detergent monthly to remove the dust and lint that the mold comes in along with (always mold spores in the air) and grows on, and keeping your moisture level down. Run the bathroom fan from the start of the bath or shower (and when washing walls) NOT from the end, and leave running for about 1/2 hour + afterwards with the bathroom door open - more on humid days when the water does not evaporate off the walls and mirrors quickly. Leave shower doors open while doing this, so moisture in the tub/shower enclosure can circulate out and be gotten rid of.

If you are seeing dark spots on the wall above your shower, it is most likely Mildew...not mold. Even though they are in the same family, mildew grows on skin cells and soap scum and when it goes airborne, it dies. Mildew is a very common issue for bathrooms, hence all the tub and tile cleaners on the market. The walls should be cleaned and if they are paintable, you should paint with an anti fungal paint, like KILZ 2 or Zinsser's. This will help prevent it from returning. Painting and doing a quick wipe down once a week will help keep your walls clean...But you always run the risk of growing mold or mildew in a bathroom because of the increased relative humidity and lack of air movement. Good luck.
