Does mold go away on its own?
Mold will not go away on its own.
The thing about mold is that it will keep on growing as long as conditions are favorable and as long as it has access to a food source. The kitchen is the perfect environment that has both humidity and moisture, so it’s safe to assume that the mold problem will remain unless they’re physically removed.
The “completely dried” out appearance doesn’t mean that the mold you see on the surface is no longer harmful. That only means that the mold is dormant since it has no access to the key elements it needs to survive—food and moisture. But once the surface gets exposed to water, and once the weather starts bringing in more humidity, you can expect the mold to be in its active and viable state once more.
The cycle will continue and through time, that moldy patch can grow and cover portions of the kitchen ceiling and other parts of the house. The best way to address this issue is to contact a mold removal service like AllStarMoldRemoval.com.
