I have noticed some white residue after fogging on some flat surfaces – what is this?
Residue is a normal result of overapplication of Concrobium Mold Control on nonabsorbent surfaces. It is the result of evaporation of the water content from the solution as it sits pooled on a surface. The residue can be easily wiped away with a cloth dampened with Concrobium Mold Control. Adjust application rates accordingly for subsequent applications.
