If you see mold near water pipes, waste lines, icemaker lines or plumbing fixtures, chances are the mold is feeding off a nearby leak. Let the water run while you check the pipes and surrounding area for damp spots to see if there’s mold from water leaking. Remember that water can travel in any direction—down, sideways or even up when it wicks into absorbent material like drywall—so the actual leak may be some distance from the mold. Once the leak is found, fix it. This portable work light is perfect for scoping out problems inside cabinets and other hard-to-reach spaces. Learn how to clean black spots in the bathroom here.
