Spray With Cleaning Solution

For surface stains, bleach is the best mold remover for walls, but if you need to clean a little deeper, white vinegar is the best option.

A solution of bleach – not really great on drywall
Great for non-porous surfaces, but it won't penetrate deep into your drywall because bleach doesn't penetrate porous surfaces. What you might find is that the water seeps in, creating more moisture on the inside to promote mold growth.
The good news is that if you kill the mold right away, you can usually save the drywall. If the mold has been lingering there for awhile, you might need to replace the contaminated section.
Some people are sensitive to molds. For these people, exposure to molds can lead to symptoms such as stuffy nose, wheezing, and red or itchy eyes, or skin. Some people, such as those with allergies to molds or with asthma, may have more intense reactions.

We know that black mold, along with many other types and colors of mold, can trigger severe allergies (stuffy head, headaches, itchy eyes, sinus issues, etc.) in some people who are sensitive.

It's often used as a natural and nontoxic alternative to cleaning chemicals when it comes to killing household mold. Cleaning vinegar, which contains 6% acetic acid, is the best type for killing mold.
So you can see why allowing the vinegar to sit for sometime is beneficial, but for too long and you're only wasting time because the vinegar will dry out eventually and become less effective. Also, you risk causing damage to the area beneath the mold when you leave the vinegar to sit on it for too long.
Borax solutions are excellent for removing mold on walls, tiles, or around plumbing. Here's what to do: Combine one cup of borax with one gallon of warm water. Add several tablespoons of soap, vinegar, or baking soda when targeting more difficult areas.
