Causes of Mold Growth Inside Kitchen Sink Cabinets
Before you even embark on cleaning, it’s good to know why your sink cabinet is prone to mold build-up.
1. High Humidity and Moisture
Due to the system of drain pipes, the walls of the sink cabinet tend to have high moisture content. This makes it very conducive for mold to grow and spread. The entire kitchen also experiences high humidity levels from cooking appliances, humidifiers, dryers and steam radiators.
It’s recommended to keep the relative humidity in your indoor spaces at between 30 and 60 percent.
2. Leaking Pipes
If the sink drainage pipes are leaking, the sink cabinet will experience dampness and therefore likely to attract mold growth.
3. Poor Ventilation
Poor ventilation results in high moisture and humidity in the kitchen due to restricted air movement. This creates suitable conditions for mold to grow.
Signs of Mold Growth in the Kitchen Sink Cabinet
Molds are very likely to grow and thrive in the kitchen sink cabinet due to the dark conditions and plumbing features inside there.
Molds come in different colors and are associated with a musty smell. Typically, mold growth can be greenish, grey or black in color. However, it can also appear in other colors including white, brown, orange, red, pink, purple, pink, blue or yellow.
If you see clustered spots and thread-like lines on surfaces, then you could be having mold growth. A wall that is infested with mold appears wet and damp even when the humidity is low.
Too much mold growth in the house, can cause constant sneezing, itchiness in the eyes and nose.

How to Clean Mold Growth
Step #1 – Safety
During mold cleaning, you’ll definitely come into contact with mold spores and other debris. Prolonged exposure to these particles can result in allergic reactions such as eye and nose irritations, sneezing and skin irritation. They can also cause breathing difficulties and other respiratory complications.
Therefore, the first thing to do before cleaning mold growth is to wear protective gear including a mask, gloves and safety goggles.
In addition, ensure that you open the windows so that mold particles won’t become concentrated in the kitchen.
Step #2 – Prepare the Cabinet for Clean-Up
Most people use the kitchen sink cabinet to store some items such as cleaning brushes, dish soap, trash bags and so on. Remove items from the cabinet to allow ample space during cleaning.
If own a HEPA air purifier, place it near the cabinet and turn it on so that it can trap escaping mold particles. This stops the spread of mold particles to other
Step #3 – Scrubbing and Disinfection
Make a cleaning solution using warm water, distilled white vinegar and a commercial mold disinfectant. Damp a soft cloth in the solution and use it to scrub all the surfaces including the plumbing components. Avoid using household bleach since it can fade the surfaces of your cabinet.
If the mold has seated for a long time, it will require more thorough scrubbing to get rid of. Use a bristle brush to scrub the remaining stains.
Step #4 – Spray the Surfaces with a Mold Disinfectant
Spray all the surfaces and plumbing components with a mold disinfectant. Allow about 10 minutes so that the disinfectant can kill the mold spores.
Step #5 – Rinsing
Using a sponge, wipe the surfaces to remove debris that have been lifted by during scrubbing. This is also meant to rinse the mold disinfectant.
Leave the cabinet open and give it time to dry.
All the items that were removed from the cabinet should also be cleaned and disinfected to kill mold before being returned.
How to Prevent Mold Growth
Moisture and humidity are main reason why mold growth lingers in your kitchen sink cabinet. Unfortunately, you can completely eliminate moisture and humidity from your kitchen.

- Install dehumidifiers in the kitchen to maintain humidity to the recommended levels
- Do not keep wet cleaning brushes, sponges and towels in the cabinet.
Studies indicate that it’s impossible to completely eliminate mold growth since it thrives as a result of high humidity and moisture. The best remedy for mold growth is to clean and disinfect affected surfaces to prevent its spread to other areas.
It’s also recommended to reduce moisture content and humidity levels to discourage mold growth.
