Bleach can be effective on mold, but we do not recommend that you attempt to use it when cleaning mold yourself. Bleach is far more toxic than vinegar, and is risky to use. It's also much harsher than vinegar, and is much more likely to damage and stain not just hard surfaces, but drywall as well.
Vinegar is best to use on porous surfaces and is considered a safer option for removing mold. Advantage of Using Vinegar: White vinegar is a safer solution to tackle a mess of household mold. Unlike bleach, vinegar does not emit toxic fumes. Vinegar is effective when combined with water.

White vinegar, also known as distilled vinegar or spirit vinegar, is made by fermenting grain alcohol (ethanol) which then turns into acetic acid. Water is then added to the vinegar, so white vinegar is made of five to ten percent acetic acid and ninety to ninety-five percent water.
Cleaning Walls
Put the solution into a spray bottle, and apply a light layer onto the wall (don't oversaturate it). Let the solution soak in for a few minutes, then wipe it off with a soft sponge. Rinse the walls with a clean, damp rag to remove any residue once you're done cleaning, and let them air dry.

Use two parts water to one part bleach, lightly scrub the area and leave the bleach on for a few minutes (but don't saturate the wall) so it kills the surface molds and penetrates the wall to get the roots. Blot dry with a clean cloth afterward. It works best on hard non-permeable surfaces.
Vinegar is better at killing mold because it can work on both porous and nonporous surfaces. It also terminates molds at their roots so the mold won't return and is also safer than bleach. You can even combine it with baking soda to make it more effective.
