It is VERY IMPORTANT for people to know that Bleach DOES NOT KILL MOLD!!! It only removes the color so to speak... it will come back in a few weeks, or less. I have seen so many problems pop up from Do it yourselfers... when it comes to MOLD. I had a friend that thought they had a little bit of mold, so they cut a 12"x 12" section out. and hit a mold pocket. What was worse, it was STACHY and they infected there whole home. Instead of spending $ 1,000 on a clean up, they ended up paying over $7,000 to scrub their whole house down.
I wish I had the time to tell all the Horror stories ... Please homeowners, DO NOT attempt to tackle this your self....

Along with the DIY suggestions for tools needed, don't forget to wear clothing or Tyvek full body suit and booties that can be disposed of immediately after the mold remediation process. Also use a heavy duty contractors trash bag for disposal of loose items, ie.. drywall, insulation, carpet and pad etc... Twist the neck of the bag and wrap it with duct tape and dispose of properly. Over protection is better than not enough. It's not worth getting sick or causing others to get sick especially kids or pets by not using the necessary precautions.

Pretty good post. I'd advise people to be careful mixing chemical to remove the mold and safety equipment is a must when doing this.
Maybe its better to hire a pro.

You may easily remove mold, but be precocious use gloves, mask and brush for cleaning. Vinegar or any other bleach product is used to clean mold. Spray vinegar on mold leave it for sometime, then scrub it with brush or cotton cloth, mold will disappear. Make sure that your house must be well ventilated so that it dry the air inside, so that mold will not form in future.

We can use vinegar or bleach for removing mold, these are Eco-friendly products so does not cause any harm to us. For this spray vinegar into mold and after sometime scrub it with cotton cloth. In future make sure that your house must be well ventilated just to pass the air, so that no moist will occur.

Unfortunately, this article is filled with incorrect information.
Bleach should only be used for hard, impervious surfaces.
Using bleach on wood or other porous surfaces can actually promote and feed mold through water penetration.
Please do thorough research before attempting DIY mold remediation.
Don't depend on any single source... even reputable sites like this can give bad advice.
Also be sure to read and understand the manufacturer's instructions for any product used.

MY HOUSE SMELLS LIKE MOLD
We have seen it many times. An owner or family goes away for a period of time, whether a few days or a few weeks. They return to their home to find that their home smells like mold. There is no apparent source of water, but the smell is noticeable, and the owner has just concerns regarding the cause.
Mold growth requires an event to have occurred. This event may be major and obvious, or something that requires a thorough exam to determine what exactly happened. If the event is substantial, like a broken pipe, hot water heater, or a/c condensate leak, the inspection is pretty quick, and the answer definitive. There may be noticeable water damage and with a dwelling closed up for a period of time, the smell of the resulting mold growth can become concentrated and very noticeable.
There are other times, however, when there is no obvious sign of water damage, but yet there is a definite smell of mold. In this case, a more thorough investigation might be required. A moisture meter is typically used to moisture map the building or infrared photography can be used to locate moist, or cooler areas of building components. All this is done to find hidden moisture and mold. Sometimes a leak under a kitchen cabinet might allow water to remain trapped under the cabinets or tile. Sometimes a leak from the outside results in moisture that is contained behind baseboards. Wood or tile flooring can conceal water, and wet carpet from a slab leak might not be obvious. Leaks in A/C ducts could cause excess condensation in ductwork and leak into attic spaces. The investigator is looking for wet material, and the source of the water that caused it to get wet. In each of these scenarios, you may never see the water, but you smell the mold.
A qualified restoration company might well find the cause of the moldy smell, but sometimes they are stumped. In this case, you might call a “Mold Assessor”. If a mold assessor is called in for the investigation, he will be looking for all of the above once again, and then probably take air samples from the suspect room or rooms, as well as an air sample from outside the dwelling for a comparative analysis. He might also take a sample from a part of the dwelling that does not have that moldy smell. The object of this inspection would be to determine if you have an elevated airborne mold condition in your home.
If an undetermined water leak is suspected, you could call a “leak detection” specialist. Some plumbing companies have the equipment and expertise to do this, but many plumbers use specialists themselves. A very small leak in a pipe is often difficult to find. Sometimes the pipes need to be charged with compressed nitrogen. When this gas leaks through a break in a pipe, the noise is detectible with the use of sound monitoring equipment. Leaks that are difficult to find are often detected using this method.
If there is even a small amount of water intrusion into a property, and if the relative humidity goes up, and exceeds 65%, and if the temperature inside the building becomes elevated, there is the potential that a serious mold condition could develop. In such a situation, mold growth could be observed growing on anything organic in the building. Once these conditions occur, the whole property is usually treated for the mold contamination, and many content and porous items may be deemed unsalvageable.
Mold can remain dormant in a building for many years, and remain inactive until it becomes wet again. If it remains dry and dormant, it will not smell. The smell of mold is the result of the off gassing of the mold, or fungi, digesting whatever it attacks.
The State of Florida now regulates the mold inspection and remediation industry. It is important to know that if you hire a “Mold Assessor” or a “Mold Remediator” to perform services, you should verify their licensing credentials.

Wow, thanks so much for the tips! That is really awesome! I have been working hard on cleaning ducts. It has a been a bit of a struggle to get the mold out of the duct cleaning. But I have found a lot of place that offer advice. One that has proven trust worthy has been www.ddkductcleaning.ca Does anyone know any other method that could work for duct cleaning?

We had our deck refinished September 2011 and it looked beautiful - within a month we started to see black spots and now - June 2012 - it looks horrible! I tested a small area with bleach and it immediate looked 100% better - so I guess I have a project to do! This is what I was told:
First - do a test: take a q-tip or cotton ball dipped in fresh household chlorine bleach and apply to some of the black.
1. If the black disappears right away, you have mold on the surface of your stain. That's the best place to have it. You can kill it with a rinse with an oxygenated bleach cleaner. Allow to thoroughly dry. You will need to do regular cleaning to keep it that way. When you apply a maintenance coat of stain down the road, add in a mildewcide to the stain itself that will help prevent future surface mold and mildew.
Would you agree with this remedy? If so, How do I rinse with an oxygenated bleach cleaner. Thoughts??

RobertSteller and others, we are about to buy a house and mold results just came back as over 10000 particles indoors in the walkout basement. What should we expect the owners to do to solve this problem? I don't mind a little mold, but 10000 is above EPA recommendations and I'm afraid it's in their drywall- how do I know if it's in their drywall? I don't want to cheat the sellers, but I don't want to buy a house that's molding to death!

OK... I don't know who wrote this.. and I don't care, I am a certified remediation tech. Please use proper process to do this. Do NOT do as the article suggests. This is for someone that is not well educated.. first off the guy in the picture is not wearing proper PPE. using every day clothing and then scrubing mold means you are brining the spores into the rest of the house... so why bother trying to create a negative air with a vaccumme? please go to the hardware store and by a "tyvek" coverall and use a hepa mask not a dust mask.. organic vapour prefered" then buy yourself some nice biocide like benefect or something (made from tyme oils and safe to drink up to 1 cup) clean the surfaces, double bag it and take it though an air lock ( meaning an area with air pulled to the infected area so spours are sucked into the infected area... this is also where when your done you remove the 6$ tyvek coverall...) be smart... AND to assure you.. despote what you say.. bleach does nothing more to moulds then turn them white.. some moulds are not killed byu bleach, and some heavily infected arears require sanding and then cleaning... I had a few beer and found this.. so excuse the spelling.. and good luck..... plkease be smart.. mold in small numbers is not the issue.. but some black spots can mean that on the backside of the drywall, is covered.. all depends on the infestations.... GOOOD luck and GOD Bless...

Finally, some reasonable advice. Someone NOT treating "mold" with hysteria. Cleaning and removing mold is relatively straightforward and you have even given me some good tips. Sure, there is occasion for professional remediation, but treating every black spot like it's going to kill you is utter nonsense. Thank you for some level-headed advice.

Interesting post, I am so glad that I have visited your site. Really useful information!

Like some of the other comments, Bleach is sometimes not the correct answer for some folks that are chemically sensitive. Also Bleach can burn and cause issues that some of the newer green based chemistry will not. For those folks there are companies that are making good mold cleaners without the bleach issues and will also deal with the spores that cause the allegery issues. Companies like EcoDiscoveries and Benefeact are doing excellent work in that area. A suggestion is to google Green based mold cleaners. Bleach can be fine for a lot of folks but I feel that it needs to be mentioned that it is not the only solution to this problem.
Also make sure that you can call and talk with the makers of these products as they will help with making sure that they are used correctly and be willing to work with the DIY market.

Excellent advice on the protective measures needed to remove the mold, however the idea of using Bleach as the removal chemical on drywall or structural materials is frowned upon in the industry. Bleach is effective in cleaning mold and other organic contamination on hard, non-porous surfaces, but does not effectively clean the surface of wood, carpet, and sheet rock.
Although bleach will kill the mold spores, it will not remove them. Dead mold particles still create allergy problems, and still still cause a failing score on an IAQ test. The dead mold particles must be removed with some type of encapsulation method like a Hydrogen Peroxide based cleaner or manual removal with media blasting equipment. This is the ONLY way to safely and correctly remove the problem.

Robert Stellar, how would you recommend removing mold from a hardwood floor (small amount recently developed).
May 11, 10:49 PM [GMT -5]
I am a field editor as well as a certfied microbial investigator and certfield microbial remediator. The article suggest do it yourself however in my daily practice I see the disaster peple produce because they read article like this. Often mould is hidden and people get serious health problems because they open walls.
People should not be encouraged to mess with mould.
I am happy to assist with proper tips
