Dangerous Mold Vs Mildew
The most common type of mold found in homes is mildew. Mildew is a surface mold that grows in warm, damp places like your bathroom and on fabrics and books stored in damp basements. Mildew begins as a gray or white powdery colony. It will turn black or brown if not removed promptly and often looks like soil accumulation. To test if the surface is covered with mildew or just dirt, dab the stain with a cotton swab dipped in household chlorine bleach. If the stain lightens or disappears after two or three minutes, it’s mildew. If not, it’s probably just dirt.
If you detect a musty odor anywhere in your home, then you have a high concentration of mold. It can be coming from a hamper filled with damp towels, from a damp crawlspace under your home, or carpets that have mold growing in the padding. If you smell that odor, it’s definitely time to take action to get rid of the problem.
All mildew is mold, but not all molds are mildew. Mildew can discolor and slowly harm surfaces but there are much more dangerous molds that can damage the structure of your home. If you see a black or green mold that is fuzzy or slimy and the drywall or wood underneath is soft or crumbly, there is irreversible rot, and the mold and the damaged surfaces must be removed immediately.
How To Kill Mould And Clean It
Bleach Often Overlooked these days, but I bet your mum would have reached for this first a lot of the time. Mix 1 Part good quality bleach to 4 parts of water. As advised on many Council websites, mould cannot survive bleach but be careful on painted surfaces as bleach can damage colours. Cheap and cheerful, but not the fastest to use.
Mould and Mildew Quite a few cleaning agent companies like Dettol are doing a product like this these days, good for targeting bathroom grout and fiddly areas. The bleaching agent is very good at removing the black staining created by the mould on tile grout etc. and it can be picked up from most supermarkets. Very good, but not as powerful and easy as HG Mould below.
Specialist cleaning products Many specialist mould cleaning products are available if you have particularly heavy deposits of mould, one such product is HG Mould Spray that Ive used myself and recommended to landlords and tenants . Super easy and fast, but hard to find in shops or DIY chains.
Anti bacterial sprays This gets an honorable mention. The same effective mould killing property of bleach based products, but without the stain removal. It will kill the mould but may not get rid of the black staining left behind in something like tile grout unfortunately.
How Does Black Mold Get Inside A House
Mold spores find their way inside by hitchhiking on clothes, pet fur, and air currents into your home. But spores cant get comfortable without plenty of water. This is why youll usually find black mold around water-damaged areas impacted by plumbing issues like floods or leaky pipes.
Materials like drywall, carpet, or gypsum board can soak up water, creating a perfect home for a black mold colony. If you find water damage at home, its crucial to remove all the affected materials to prevent mold from growing.

Which Respirator To Use
The type of respirator used should be dependent upon the amount of mold in the area you are cleaning. For example, if there is only a small amount of mold, a respirator that only covers the nose and mouth should be sufficient. This type of respirator can be found in most stores. However, if theres a heavier amount of mold, a half or full face respirator should be used. Again, depending on the amount of mold you are having to remove, disposable clothing may be worn to prevent mold spores from landing on your clothes.

Tackling The Underlying Cause Of Mold
Molds are all around us we breathe in their spores every day. Its impossible to prevent mold from entering any property, but steps can be taken to stop mold from finding a new home in your house. Without addressing the underlying cause of why mold is growing in a particular area, it will just keep coming back.
Molds only need two things, food and damp. Its impossible to remove the food mold needs from your home, because your property is made of it. Particle board, gypsum, wooden framing, and soft furnishings can all nourish and sustain large mold colonies. What you can control, however, is damp. When mold is discovered, look for the underlying source of water.
There are three common ways that water can cause problem mold growths:
- Maintenance issues such as leaking pipes or failed window seals
- Human error, for example not drying water in shower door tracks or splashing water around a sink
- Construction-related, usually relating to ongoing condensation issues caused by poor airflow
The first two are easy to resolve. Simply repair the problem or change your habits to be more conscious of where water is splashing and pooling. If mold is growing because of the construction of your property, it may require more extensive intervention. Installing fans or vents, replacing portable heaters, or investing in a dehumidifier might be necessary to resolve the problem.

The Path Of Resistance
Initially, Mikes landlord tried to fix the problem himself, bleaching the moldy walls. We call that spray n’ pray, said Scott Armour of the Institute of Inspection Cleaning and Restoration Certification, a global industry body for remediators. They, along with the EPA, advise against bleach for a variety of reasons, namely that fumes can be dangerous and its usually ineffective.
Bleach only works for non-porous surfaces. It cant touch the mold that has burrowed into surfaces like wood or drywall . But the most important reason bleach fails is that people dont stop the molds water supply.
First thing I do is check for leaks, in the bathroom or roof or a crack in the foundation, said Greg Bukowski, who runs the Chicago-based remediation company Moldman USA. Theres always a leak. If you dont fix that, dont bother with bleach or vinegar. Then kill and remove the mold with detergent and water, then prevent its return with mold-resistant paint like Kilz .
When bleach didnt work, Mike paid for an indoor airborne mold test, which raised more questions than it answered. We had no idea how to interpret the results. I just couldnt find any information out there that isnt written by remediation guys, he said. They told him he had the dreaded black mold, and needed professional remediation.

A lot of the online marketing is aimed at frightening you with possible disease then selling you an expensive cleaning solution or paint that isnt needed.
