How do I remove small amounts of mould myself? | Ask RCW | R.C. White Ltd. General Contractors

To clean a small area, such as window frames or wall surfaces measuring no more than 10 square feet or 3 square metres:

wear household rubber gloves (not vinyl but the type used for dishwashing);
wear a mask rated N95, which is capable of filtering fine particles and available at home improvement stores;
wear safety glasses, even if you wear eyeglasses;
use an unscented detergent and water or a mould-control product sold as home-improvement stores;
rinse the area well with a clean, wet rag;
allow to dry completely.

Is bleach an effective DIY mould removal method?

Bleach has been used for years as a home remedy for mould but it actually has many disadvantages, and indeed some dangers. The fumes themselves are an irritant and a particular hazard to anyone with respiratory concerns. When mixed with other cleansers, for example, bleach and other chemicals such as ammonia can combine to produce a toxic gas.

And bleach only works on non-porous surfaces making it ineffective for drywall and other porous materials such as wood. It may remove the surface mould you can see, but it will not reach the root-like structures mould sends into any porous surface. So, if the right moisture conditions return, so will the mould.
