How To Effective Remove Mold In Your Home Or Business
There are several products that can be utilized to kill and remove mold. Some effective products that kill mold are:
- Tea tree oil
- Grapefruit seed extract
While these types of products can be effective in killing mold, they are only efficient when you recognize the first signs of mold growth and manage to prevent its development. In addition to eliminating the mold you see, you must also eliminate the source of the moisture that allowed its appearance in the first place. For many people, while doing it yourself may be an option to remove the mold it is often done incompletely providing only a temporary solution to your mold problem.
It is always best to hire a professional mold remediation company when you see mold but, if the mold in your home is not toxic and the area of mold growth is small then you can try to perform the mold remediation on your own.
Reader Question: Is It Ok To Apply A Sealer Or Wood Preservative Over Black Stains On Plywood Roof Sheathing
Last September I had a new garage roof fitted and within 7 months the plywood used inside developed black mould spots. The company that fitted the roof said it was caused by condensation. Having wiped the roof with a mild detergent I was left with black stains on the plywood. I would like to know if it would be ok to put a wood preservative on it despite the stains – don’t want it to come back.
Would appreciate your advise? –
Yes you can apply a wood preservative, leaving cosmetic black stains under the preservative.
But if you do not find and fix the cause of condensation I’d still expect future trouble. You may find stains or mold appearing on other wood or mold-friendly surfaces in the same area if indoor moisture levels are high, or if there is building insulation present that may become mold contaminated.

Removing Mold From Drywall Or Ceilings
Drywall and ceiling materials are porous, so the mold you see on the surface most likely has threaded its way below the surface, too. Spray the surface with the homemade bleach-based mold remover until damp but not dripping, and let the area air-dry.
Then, respray it, wipe away any residue with a fresh cloth, and reapply a final light round of spray. Let this dry overnight, and the spray will continue killing mold as it dries.

How Much Mold Must Be Removed
Following a properly executed mold cleanup, if there is a future mold problem in a building it is unlikely to be due to having left behind an “inoculation” of problem mold, and more likely to be due to a new building leak that was left unattended.
Good practice for the extent of and means of physical removal of moldy debris varies by material.
For drywall we remove all visibly moldy material and continue removing drywall to no less than the next adjacent stud, rafter, or joist.
For fiberglass or other porous building insulation which has been wet, we remove all suspect insulation and all insulation within 24″ of the suspect material. However if moldy and wet conditions were long-standing in a building, removal of all of the insulation may be necessary.
For building insulation that has been exposed to dusty conditions or high levels of airborne mold it is often more cost effective to simply remove the material, clean the surfaces, and re insulate than to spend that same money on testing the insulation for mold.
Generally it is less costly to remove and discard more material than to “finish” the job and then discover that it needs to be done over again because the initial work was insufficient.
Framing lumber, or roof or wall sheathing that is not rotted does not need to be replaced. Unless framing lumber has been actually damaged, such as by rot, replacing it due to mold contamination is not justified and wouldbe improper.
Removing Mold From Wallpaper
Use the natural mold remover spray on finished, painted, or wallpapered surfaces. Spray the area well, then immediately scrub it with a clean cloth or brush to remove the surface layer of mold. Then lightly respray the area, using only enough to dampen the spot you dont want it dripping. Wait 10 minutes and wipe it with a clean, fresh cloth. Let it dry overnight without rinsing the remaining acetic acid from the vinegar will work overnight to finish killing mold you cant see.

Does Bleach Really Kill Mold
Mold is terrible. It is smelly, annoying, and destructive. Not only does it stain surfaces within the house, causing your space to look very unpleasant, it can also cause damage to your structures by eating away at your building materials like walls and furniture. So it only makes sense that once you notice mold, you want to get rid of it immediately.
The idea that bleach will help completely get rid of the mold in your home is a common misconception that has been sold by big bleach marketing agencies and websites.
The primary function of bleach is to disinfect and to bleach .
Chlorine bleach can help eliminate mold on hard non-porous surfaces like sinks, bathtubs, tiles, or glass. This is because the roots of the mold do not penetrate through this surface and so it is easily wiped off.
However, when mold grows on a porous material like wood or drywall, it spreads its root deep into the material to reach more nutrients. So when you apply bleach to such a surface, you are merely changing the molds color on the surface. Bleach quickly dries off on the surface and will not reach into the deeper part of the material to the molds root. So, in a few days or weeks, the mold regains its color and grows back to become even worse than it was before you applied the bleach.
The fact is that bleach might work well on a non-porous surfaces like tiles, sinks etc., it is not worth trying due to the numerous health hazards associated with it.

Find The Moisture Source
Black mold removal is important. But first, one must identify that it is black mold. First, look at the color, followed by the smell. Black mold is black or even dark grey in color, and often smells wet and musty, as it usually grows in areas with a lot of moisture. Black mold is also usually noticeable in the home if you experience a burning or scratching sensation in your throat or lungs. Black mold is dangerous, and can greatly affect your health if left untreated, so it’s important to remove it as soon as you’re aware of it.
Before you can begin any black mold treatment, youll need to perform a black mold test and find the source. Its often the result of excess moisture in a particular area. Youre most likely to find black mold in areas of your home that you dont visit as often like the basement, but it can pop up anywhere. Here are a few common moisture sources to look for:
- Faucets and fixtures. Sink, shower and bathtub faucets and fixtures that are leaking can lead to the growth of black mold over time.
- Exposed plumbing. Damaged or leaking pipes, especially in warmer temperatures, can often create black mold in areas like basements.
- Water heaters. A small leak can create black mold in your basement or water heater closet.
How To Get Rid Of Mold
