How do you get rid of mold in a bathroom?

There are mold stains on the ceiling of my bathroom, spots about 1 cm in diameter each). I would like to know which non-toxic product I can use to remove them. There is no fan in the bathroom and no window. There is a skylight that is not waterproof and it is very humid in summer. Will a dehumidifier help?
The first thing to realize is that mold grows in humid environments. So along with getting rid of it, you should take steps to prevent it from happening again in the future. You have a combination of factors at play here that may be contributing – lack of a bathroom fan or a window you can open means humidity will be around longer, and the bathroom will perhaps not have enough time to dry out before the next shower makes it humid again.
So, installing a bathroom fan installed should be a top priority. It’s still possible that you have a leak of some sort that is causing the mold, but the smart money would lay odds on the lack of a fan, so deal with a fan first and then see if there is a problem. Skylights are problematic for condensation at the best of times, that is made even worse by being in an unventilated bathroom.
这是否导致了天花板上的霉菌很难确定,是倾斜的天花板吗?天窗上的水汽会不会顺着天花板往下飘呢?再一次,一个浴室风扇也会有帮助。如何清洁模具:根据CMHC(加拿大抵押贷款和住房公司):作为指导原则,他们认为受模具影响的面积为一平方米或更小的区域是“小区域”。“平均面积”等于或小于3平方米。除此之外,他们会认为这是一个“很大的受影响的区域”,由于健康风险太大,不建议自己清理一大片区域。你可以联系CMHC获得合格的专业人员名单。
How to clean mold in small areas: Whenever you set out to clean mold and mildew, first wear gloves, a respirator mask and safety glasses. We would not recommend using toxic or very strong cleaning products like bleach. For drywall (gypsum board) it is recommended to use a damp cloth and baking soda or some unscented detergent. Rub the surface with the detergent solution, rinse with a clean damp cloth, and dry the surface. Avoid over-wetting the drywall during cleaning. Before and after, vacuum on and around the surface with an appliance equipped with a high efficiency filter (HEPA). Medium sized area of mold: Something this size can be done in much the same way as for a small area, but it is better to create a separate work area from the rest of the house by sealing it off with plastic sheets attached to the walls and ceiling.
湿度和通风在没有浴室风扇的情况下,你应该尽可能地降低房间的湿度,清除房间里所有会导致潮湿的地毯,然后用橡胶滚轴擦干墙壁和淋浴器底部。把毛巾放在另一个房间晾干也会有帮助。不要让积水留在浴缸里,把马桶盖压小,以减少水分蒸发。If you wanted to invest in a HRV unit but retrofitting ductwork looks too complicated, thenconsider a ductless HRV unit instead, see here for details. There's also a video onhow easy these ductless retrofit HRV units are to install in an outside wall.
In the absence of a bathroom fan, at least having a dehumidifier (in the bathroom if possible) would help reduce relative humidity, relative humidity levels (RH) should not exceed 50%.
