There are some drawbacks to consider. The effectiveness claims, while promising, may vary based on the severity of the mold issue and the specific surfaces being cleaned. Although it suggests lasting up to a year per bottle, users may find they need to reapply it more frequently, depending on conditions.

While the product's ease of use is a significant advantage, potential users should note that its effectiveness can depend on the extent of mold or mildew damage. In cases of severe infestation, more extensive treatment may be necessary. Furthermore, while it claims to be safe on multiple surfaces, testing in a small area first is always a good practice to prevent any unexpected reactions.
