The presence of a black jellylike substance in moist areas of the kitchen or bathroom is likely a fungus called Aspergillus niger that occurs naturally in our environment and travels through the air. Given the right growing conditions, Aspergillus niger will colonize and produce black stains on surfaces.
If you find black slime around the holes of your shower faucet, it's due to oxidized manganese and harmless bacteria feeding off the minerals in the water. This might also show up in the form of black stains in your toilet bowl. Most water in the United States contains dissolved manganese, along with other minerals.
Sometimes, a black jelly can build up inside taps, and wash out into the sink. This is caused by airborne spores that like to grow in warm, damp places. Bathrooms and kitchens are usually the perfect place for this to happen. Mould, also known as biofilm, does not come from your water supply.
Once a month or so, throw a handful of baking soda in your sink drain and chase it with a kettle full of hot water. Baking soda is a powerful odor absorber and cleaning agent, which may help prevent drain buildup.
Soak a rag or a cloth in vinegar or lemon juice and wrap it around your tap, ensuring all areas are covered. Secure the cloth with an elastic band and leave for an hour. Occasionally squeeze the cloth to release more of the acid onto the tap. Remove the cloth and wipe away the limescale.
Taps: Black slime associated with tap fittings can be easily removed by cleaning inside the tap with a small brush (or old toothbrush) dipped in a mild bleach solution. You should run water to flush the tap before use.
Boil two cups of water and pour down the drain, then run the hot water from the tap for several minutes. Pour a quarter-cup of baking soda into the drain. Pour one cup of vinegar into the drain and allow it to sit for 15 minutes, which gives the combination of baking soda and vinegar sufficient time to kill the mold.
Yes. This is the main reason that you need to take urgent action. Drinking from a moldy water bottle can make you sick because you are swallowing mold. Mold can cause all kinds of problems including respiratory problems, nausea, cramping, diarrhea and unexplained infections.
If you are experiencing dark gray/black “stains” or slimy residues in a toilet, at a sink faucet, or even on a shower head, the good news is you don't have a water quality problem, and the water is not harmful.
Black mold is a fungus that grows in warm, damp areas. Its spores may mistakenly trigger an allergic reaction in your immune system. An allergic reaction to black mold may cause various symptoms, including coughing, sneezing, congestion and irritated eyes. However, it rarely makes people very sick.
Fortunately, vinegar is an excellent natural remedy for dissolving limescale buildup and is safe for household use. To clean black taps using vinegar, mix equal parts of vinegar and water in a bowl. Soak a cloth in the solution and scrub the taps gently.
Limescale from hard water is usually white but can become discoloured by traces of other minerals or metals. For example, traces of copper from plumbing materials can turn limescale grey, green or blue while traces of rust from pipe work can turn it orange, brown or even black.
So does coke remove limescale? Yes. The acid in coke will help to dissolve limescale and there are several examples of it being used to clean toilets, descale kettles and in other circumstances.
The best way to remove limescale from the shower, sink & bath is using: Bicarbonate of soda & vinegar - combine 2 parts bicarbonate of soda with 1 part white vinegar to make a paste and apply to areas with hard water stains. Leave for 10 minutes then scrub vigorously with the abrasive side of a sponge to remove.
Where the water hits air — on the aerator of a kitchen faucet or on a shower head, for example — the minerals combine with oxygen. Oxidized iron forms the yellowish or reddish deposits we know as rust; oxidized manganese is brown or black. The particles can also settle out when a glass of water is poured.
Limescale is a chalky white colour and will no doubt stand out on any black brassware, so to keep that finish for longer you have to keep on top of it. Just regularly cleaning can keep limescale away, so don't get lazy!
Ingesting limescale may be unpleasant to the palate (not to mention crunchy!) but it isn't harmful. The minerals which form limescale, magnesium and calcium, are actually very important to the human body. In some areas hard water is actually a supplemental source for these important minerals.
For the upper parts of your tap, soak cotton wool or a cloth in either white vinegar or lemon juice and wrap it around the taps. If you want to be sure, secure it in place with an elastic band. Leave it for a couple of hours or overnight, depending on the amount of limescale.

Black/Dark Brown Water Stains
Cause: Black or dark brown staining around your drains and fixtures is usually caused by high levels of manganese. While manganese is natural and in small amounts can actually be healthy, high levels in your water can be a nuisance to deal with.
Homeowners can handle cleaning about 10 square feet (roughly 3 feet by 3 feet) of black mold on their own. If the patch is small enough, a combination of bleach, water, scrubbing, and ventilation should do the trick. Before treating mold on your own, prioritize ventilation and protective gear.
Black mold, as the name implies, is often dark in color. When searching for black mold, look for circular-shaped spots that are black, dark green or dark brown. Some black mold can also take on shades of orange or have flecks of white within it. Most of the time, black mold has a slightly furry appearance.
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.
