Cleaning Mold From Wood Trusses And Cross
In an area of high levels of mold growth or moldy dust and debris, the irregular surfaces formed by wood trusses and alsoby older wood cross bracing between floor joists prevents thorough cleaning of surfaces and creates many dust collectionpoints.
A similar construction detail where significant moldy dust reservoirs may be left in place is the upper surface of woodfurring which has been nailed across the under-side of floor joists to support ceiling tiles.
Because the surfaces formed by trusses and cross bracing can form a significant dust and debris reservoir, I always checkthese areas during a mold remediation clearance inspection. If work has been hasty or incomplete, these are among the firstareas to be under-cleaned.
Spray process cleaning, media blasting , and HEPA vacuuming are effective for these areas.

Does The Building Need To Be Sterile Is The Object To Reach A Mold Spore Count Level Of Zero
No, the building does not need to be sterile, nor should you seek a zero mold count. We have worked on cases where sterility was a necessary cleanup goal: medical facilities such as in operating rooms and treatment rooms. But in a normal office or home there is always some airborne mold along with lots of other airborne particles in building dust.
No washing, sanding, scraping, or other surface cleaning will remove all mold spores from wood where mold was previously found. It is unlikely that most construction materials, even when new, are free of mold spores, nor iszero mold a reasonable nor possible objective.

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.

How To Keep That Brand New Look
Most of the teak shower furniture sold today comes with a coating of teak oil or light stained finish already applied. The color will eventually fade over time, so you may want to reapply a coat of teak oil every few months or so. We normally discourage the use of teak oil on outdoor furniture, but the wood used in shower furniture is usually a lower grade of teak that benefits more from applying oil.
Apply a teak oil after youve cleaned the furniture and allowed it time to dry. Using a sponge or cloth rag, rub a small amount of oil onto the surface of the wood following the direction of the grain.
When the entire surface has been coated, wipe up any excess oil. Then give it about one day to dry before using again. Dont leave any oil-soaked rags crumpled up after use, as this can be a fire hazard. You should soak them in water and then dispose of them.
If you dont mind a faded gray color, then its not necessary to treat your teak shower furniture with oil. A regular cleaning to remove soap scum should be sufficient.

How To Remove Black Mold From Wood Easily
With hazards ranging from health problems such as allergies and respiratory difficulties to the unsightly appearance they cause on wood, mold is a fungus you want to get rid of as fast as possible. Black mold is a type of mold, some species of which are potently toxigenic, i.e., they produce mycotoxins that can lead to serious health issues.

Choose The Right Cleaning Solution For The Job
You will want to select a cleaning solution that will effectively kill or remove the mold on wood. To do that, you need a mold killer that will penetrate the surface of the wood. Luckily, there are lots of options.
Frequently, our customers ask us, Does vinegar kill mold? or Does bleach kill mold? The answer is yes these are both useful household items.
Mold killing solutions can include:
- Regular cleaning detergent
- Commercial fungi removal products
The best solution for how to remove mold from wood will depend on the severity of the mold damage and the mold species. For example, for small surface growths, all you need is distilled vinegar. But if you discover worse mold damage or more severe strains, such as black mold, youll probably want to go with the commercial mold killer.
WARNING: Whatever you do, make sure not to combine bleach with any solution that has ammonia in it. This mixture will cause a chemical reaction that could lead to an explosion. The toxic fumes from this can cause deadly infections or even kill you. So always play it safe. If youre not sure if something contains ammonia, do not mix it with bleach no matter what.
