What is mold?

What is the meaning of mold? Well, mold is part of a group of common organisms called fungi. It comes in many forms but is typically green, grey or black. Mold spores generate in moist, damp, humid conditions and live off the proteins from timber, leather, ceilings and walls.

The spores tend to germinate in the sub-floor area and evaporate up into homes where there is high moisture content. Mold thrives in damp, dark areas. That’s why you can often find it in cupboards, behind furniture and on the underside of dresser drawers.

The most common types of mold found at home are aspergillus, cladosporium and stachybotrys atra (also commonly known as the toxic black mold). The Aspergillus is one of the most common species and they’re usually found on food or in the air conditioning system. As for clasdoporium, they usually in green or black and they grow in areas like the back of the toilets, painted surfaces and air ducts. While these mold do not pose any harm to human’s health, they can cause allergy such as rashes and sore throat.

Last on the list is the toxic black mold and as suggested by its name, long exposure of the stachybotrys atra can pose a serious health problem like chronic coughing, rashes, sneezing, irritation and headaches. This type of mold feeds on organic matter like drywall, carpet and floorings that have been exposed to moisture.

What kills mold?

What kills mould? For non-porous materials, use some mild detergent and a little elbow grease to work it away. Picture: Getty

There are several products (organic and non-organic) in the market that kill mould. Here is the list:

1. Chlorine bleach

This common household bleach is not only effective in cleaning your house, but it can also be used to destroy mould and remove any discolouration caused by it. However, it can be harsh on certain surfaces, so remember to dilute it before using it.

2. Hydrogen peroxide

Though it’s less harsh than bleach, hydrogen peroxide can do the job just as well. The only downside is that it works slower than bleach, but hey, at least it has no toxic fumes and it’s less likely to destroy the surfaces of your furniture.

3. Distilled white vinegar

This kitchen staple can clean stainless steel and remove grease, grime and dirt. And you know what else vinegar can do? Break down the mold structure and kill it. It’s another non-toxic option that you can consider but do note that while it’s effective in killing mold, it won’t get rid of the stains. You may want to pair this up with a household cleaner to get the job done.

4. Baking soda and borax

At this point, you’ve got to ask yourself this: what can’t baking soda do? Both baking soda (sodium bicarbonate) and borax have high pH values and this will prevent the survival of mold. You just need to mix both these products with water and your mold problem will be gone in no time.
