If you have an undermount sink, regularly clean and dry the silicone caulking between your sink and your counter. Check for cracking or moldy caulk, and replace if you see an issue. If you do this yourself, you'll need to thoroughly remove the old silicone and recaulk, allowing sufficient time to dry.
The one big drawback to undermount sinks is that water can get in between the sink and the counter, causing mold problems — especially with countertop materials that are not water resistant. Proper knowledge, installation, and maintenance can keep these problems at bay.
Unfortunately, kitchens are prone to mold and mildew growth because of the high levels of moisture and humidity that are present in them. Mold in kitchens is most often found under the sink, in and behind cupboards, around window sills, behind appliances and kitchen furniture, on walls and around taps or sinks.
Most undermount sink manufacturers recommend that you use pure, 100-percent silicone sealant for undermount sink installation. Silicone sealants are designed for resilient flexibility and have good adhesive properties. If an ordinary caulk was used to seal the sink, it likely will fail quickly.
Mold loves the space under your kitchen sink because it's relatively warm, has the potential for moisture, and is full of "yummy" surfaces like wood and drywall. (With mold, there is no accounting for taste!)
Instead of using bleach and water for cleaning, you can also use natural products including vinegar, tea tree oil or grapefruit seed extract. These substances have anti-microbial properties and can also help remove the smell of mold in addition to disinfecting the area.
Moisture absorbent
Both chalk rock and gypsum are incredibly absorbent, significantly reducing the moisture content wherever they're placed. Not only that, but by removing moisture from the air, chalk also removes musty odors associated with overly humid areas.
Silicone sealant is the best type of caulk for kitchen use. Silicone is waterproof and non-toxic. It is flexible, durable and rarely cracks. It is capable of adhering to a wide variety of substrates, including metal, glass, porcelain and ceramic.
Properly installing and sealing an undermount sink is crucial for this style of bathroom or kitchen sink in order to make sure it's properly supported and to prevent leakage. Your counter and supports need to be able to keep the sink in its place and hold its weight safely.
So while black mold probably won't kill you, it can make you feel sick and should be removed as soon as possible.

Undermount sinks are a popular choice for many homeowners because they offer a sleek, seamless look that is easy to keep clean. Because there is no lip around the edge of the sink, it is easier to wipe debris directly into the sink, rather than having to clean around the rim of the sink.
The under-counter basin is easier to clean, easy to clean and hygienic, and the sanitary corners can also be seen clearly. But the disadvantage of the under-counter basin is that the construction is more difficult, and the bearing capacity is not as good as that of the over-counter basin. It is troublesome to install.
Offering a seamless contemporary look which is both stylish and functional, the undermount kitchen sink is both practical and hygienic.
Since undermount sinks to not have anything above the counter to help carry their weight, they need more support. They also need more solid countertops that don't suffer easily from water damage. This often makes them a more expensive sink than other options and also makes installation more difficult.
The lack of a visible lip with an undermount sink makes it quite a bit easier to clean your counters; you can sweep any debris from your counters right into the sink. However, top mount sinks are the simplest of the two types of sink to keep clean themselves.
For a stainless or metal sink (such as those commonly found in kitchens), you'll want to use a silicone-based caulk. For a porcelain sink (more common in bathroom spaces), a latex-based caulk will be a better fit. When choosing caulk, it's also important to select a color that will best suit the space.
Plumber's putty is a malleable, clay-like compound that creates a watertight seal by filling in the space under a flange to prevent water from seeping through.

Condensation or “sweating” under the sink is another commonly known issue of kitchen sinks. This “sweating,” if allowed to continue over time, can damage the pipes, floors and storage below the sink. It may also cause some areas to rot and mould may build-up, if not properly cleaned.
When water leaks from the plumbing, mold and mildew can grow. Check to see if there are any water spots or mold growth in the drywall or inside of the cabinets. You might also notice standing water or general humidity under the sink.
