When you see mold in your bathroom ceiling, you may be tempted to scrub it off with bleach and a sponge. After all, bleach kills mold, right? Yes, bleach can kill some types of mold, but it is both the mold removal technique and the source of the mold that dictates how often you will have to address this issue. In fact, scrubbing mold off a wall or ceiling or using a pressure washer to remove it from your home's exterior are probably the worst approaches you can use to kill mold. Here is why.
You Are Adding More Moisture to an Already Wet Situation
While you may be blasting mold growth from your siding or killing the surface spores on your walls, you are adding more moisture to the area. Mold thrives in wet areas, growing and multiplying its spores through the damp materials on and in which it grows. Without a very thorough drying and rub down of the areas you just cleaned, the mold excitedly begins to regrow. It now has more wet surface areas on which to stick, so unless you intend to use a hot air source (like a hair dryer) and/or a very dry towel to wipe down these areas, avoid this approach to mold removal.
You Are Actually Spreading the Mold Spores Around
Mold reproduces by spore production. When you blast dry spores with a pressure washer, the microscopic offspring take flight to other areas that are now wet because of the pressure washer. If you try to use a wet cloth and bleach mixture, you may kill the majority of the spores, but you cannot guarantee a complete eradication. It is the equivalent to trying to get ice cream off your shirt--you just spread the scope of the problem in a wider circle and produce a bigger mess.
You Are Not Addressing the Source or Cause of the Mold
The mold that you see represents a much bigger problem, one that you cannot see. When mold shows through your ceiling or wall or starts to hang out on your home's siding, there is a lot more of it you cannot see inside the walls and/or under your roof. Removing what you can see does not remove what you cannot see, and then the mold just keeps coming back. You have to hire a mold removal specialist like Firewater Restoration Services to locate the source of the water and the materials that are rotting and remove them before attempting to repair the damage.
