There are products on the market you can get at home improvement stores, but I found bleach works great.

I use straight bleach and a sponge.

go to paint store or walmart and ask for primer to cover mold will work great

I would get a professional in to remove that. Do not touch it. Especially if you are wearing contacts! You do not want to be inhaling it either.

Do not mess with mold!!!

depending on how bad it is, knock on it with your knuckles if its soft and mushy you gota cut it out and replace that section, if its solid then use sandpaper and primer and paint, if its deep add compound.

It depends on the amount of mold. If it's a small amount, then bleach should do the trick. If it's a large area, then you might need to replace the wall material (drywall, paneling, etc) and possibly an insulation behind it. Kilz is a good thing to use as well to keep mold from reoccurring.

I was told to wash the wall with diluted white vinegar and water! But black mold may have to be checked out! I am checking mold in my house and learning many things i did not know about germs!

Wipe it down with clorox and water, when it has dried, paint it with Killz paint. The mold won't return.

Good answers all. But the important thing is - in the future - leave a squeegee in the bathroom. Have the last person to use the shower to squeegee the water off of the walls and, after drying self, wipe the room down with the damp towel that was just used so it is about 99 % dry. No water = no mold. BTW, there is a huge and expensive industry growing up around mold removal. The simple fact is that there is no evidence that the mold is any more dangerous than many, many other materials that inhabit the bodies of us all.

wipe the wall using chlorinebleach and water if its small i'd recomend
5cups of water and half a cup of chlorinebleach if its very very big
use 3 gallons of water and half a gallon of chlorinebleach open a
window while doing this because thanks to the chlorine bleach there
is not going to be alot of air in the room and dry it very quickly

Warm water and bleach works as good as any. then let it dry and coat it with a sealer like Kiltz…..and finally paint. good luck

Black mold is hazardous to your health, more so than other mold cultures. so take the precaution of careful handling.

Wear rubber gloves, particle masks, and eye protection.
Also take precautions in not spreading mold spores that may cause other grow elsewhere.
if it is a small area that is affected then you can clean it up yourself, if it is a large area, it may require professional clean up.

Use a mild detergent to wipe off. If drywall is heavily saturated than you should replace it discarding it in a sealed garbage bag. also wipe down studs and other adjacent surfaces and dispose of the rags in a sealed bag.

IT IS NOT recommended to use BLEACH as it may worsen the problem and is INEFFECTIVE due to contact time and pH level.
Bleach is NOT recommended
The presence of organic (humic) materials, the pH (acidity/alkalinity) of the water, the surface material and contact time affect the effectiveness of bleach for disinfection. Since these factors are not generally controlled, bleach cannot be relied upon for disinfection. The most compelling reason for advising against bleach is that fumes are harmful but in addition, overuse of bleach will result in increased releases of chlorinated effluents which can be harmful to the environment.

make sure the moisture source is fixed to prevent future mold growth.

If you wish you can purchase special mold killers and inhibitors from hardware stores that you may spray onto the mold.

Also keep any children, and pets out of the bathroom, until you have remedy the problem

"Moldy drywall:
Clean the surface with a damp rag using baking soda or a bit of detergent. Do not allow the drywall to get too wet.

Mold that comes back after cleaning is usually an indication that a source of moisture has not been removed. Seek professional help from a trained IAQ investigator."
