How To Remove Mold From Walls (Drywall)

Trying to get rid of mold without proper knowledge or without a professionals help may aggravate the situation or result in even more significant problems than the mold itself.

The grout, if it has been sealed, cleaning will be much easier.If the grout is unsealed, it can be removed with cleaning, but it just requires a little more elbow grease than if it had been sealed.

Ammonia Can Kill Mold As Well

Ammonia should be considered an option of last resort if the mold is on your drywall.

It is a rather toxic chemical and it doesnt absorb into the drywall very well.
