how to clean the mold from bathroom walls and ceiling?
and then should I paint with Kilz and then oil base paint? what should I do to not get mold anymore in the bathroom? thanks
please let me know how much bleach? how much water?
the most important thing to do is to make sure you have a ventilation fan that is adequate. some older homes dont have a vent and because of that moisture stays trapped in the room from taking a shower. It is that moisture that is the basis of the mold and mildew.
Have a contractor install one for you. Or a really handy friend if you dont think you can tackle the job. Since it involves electricity, youll want to make sure it is done correctly. Kilz is fine and bleach water will kill the mold, ( i use a 25% bleach 75% water to do the job myself ) but they are only treating the symptoms. The disease is lack of ventilation.
One other thing that ive seen in my many years as a contractor is that sometimes the ceiling above the bathroom is not insulated very well in some spots, or all of it. What this does in single story homes is allow for warm air to be "drafted" into the bathroom and that can also cause condensation to form. This last example is unusual but ive seen it a few times. And Yes bleach does kill mold. Bleach kills almost all micro organisms. BUT, and this is important, it will not effectively kill the roots of mold in most porous surfaces, such as wood. It will kill both mold and mold spores (roots and all) on hard non porous surfaces such as glazed tile (not natural stone tile, thats a porous surface)
Bleach is the best thing to getting rid of mold.

Most cleaning experts will recommend one part water to one or two parts water. Once you combine the water and the bleach, wipe the affected surfaces and wait thirty minutes to an hour, and repeat until there is no more mold.
To prevent mold from returning, run the fan in your bathroom everytime you take a shower, or do anything else that causes condensation to build up. If you don’t have a fan, or a working fan, take a minute or two after a shower to wipe the walls and ceiling quickly with a towel, and leave the door open if possible. Also, if you don’t mind repainting, ask for mold-inhibiting paint at any store that sells paint. I hope this helps!

Xandra’s right. Pour 1 cup of bleach into a bucket of water swab or scrub the areas until wet, then leave for 10 minutes. Then rinse walls with regular water. You can also use "Lysol"disinfectant All purpose cleaner. Spray whole areas till wet and leave on for 10 minutes. Mold is scary. You need a air vent system in your bathroom.
Heres how to take care of your bathroom from now on.
1. buy bathroom caulk and seal any separations where the tub and walls are supposed to meet. 2. Seal with the bathroom caulk any separations where the tile and walls should meet. 3. If you don’t have a air vent you must wipe down your tile and ceiling after each shower and bath.Wipe them dry. then keep the bathroom door open to allow steam to leave the bathroom. Most people don’t know how to use their bathroom. They think that because they have tile they can wash and just go. No so. The tile should be wiped down of excess water. It doesn’t have to be bone dry but the excess water should be wiped away. Tile allows the water to run off of it and will not buckle as will regular walls, that’s the only difference. So keep a towel specifically for wiping the walls in your bathroom. You should clean the body dirt from the tub and walls after you shower or bath with Ajax or a foaming bubble tub and shower product or Lyso disinfectant All purpose cleaner, then after you rinse the above mentioned off, you should wipe the walls dry and leave the bathroom door open for a few hours. Its a lot of work but this is how it should be done to be safe and maintain the bathroom. I figure in all the time I’ll need to wash myself and the tub and shower and leave the shower dry and put the bathroom back in order before I shower and bathe. So when I leave the bathroom, except for some steam, its ready for the next person. This is how its supposed to be done. And I don’t know what Kilz is Good luck.

Do you have any ventilation in the bathroom? A window, or a fan? If you have a window, open it up. If you have a fan in there is it working? Those things get gunked up pretty easy and do not really work well even if it is making some noise. So clean that out too.
I say this because you will be working with bleach, and the fumes can be pretty strong.
You can either use a bucket with hot water, and pour in the bleach. Or you can use a spray bottle. This is actually helpful for the cieling or other high areas. Spray it all down, let it set for a godd five or ten minutes. Then go back and give it a good scrubbing. All the while make sure it is properly ventilated.

use white vinegar and water 20-50% , wipe down and let dry, the vinegar helps to stop mold spores settling,
also allow the flow of air, keep windows cracked open, if possible

bleach DOES NOT kill mould. It just makes it white and "invisible", but the mould will come back.
bleach also damages the finish on your tiles, weakening them and making them more prone to mould.
and it damages your silicone seals, eventually you’ll get mould growing underneath it and there’s no way to fix that.
things that kill mould:
tea tree oil, use one teaspoon in a spritzer filled with water
oil of cloves, use just half/one teaspoon in a spritzer (500ml)
spray and let it work overnight, then use a good quality cloth to rub away the mould. (oil of cloves can be bought at a chemist)
the best way to stop mould is to dry off your shower after every use. keep a squeegy in the shower.
