First, it is extremely rare for BIOSWEEP® to damage sensitive items such as fabrics, carpets, rubber, or foam. After years of extensive use, BIOSWEEP® has never damaged electronic components.
Usually when an odor cannot be fully eliminated, it means an odor-generating source has not been fully removed. There are reasons why: porous materials are odor sponges and sometimes need to be removed. In homes, we see this most commonly in plastic sheeting, carpet pads, and filters, which can get impregnated with odor. The simplest solution for odor removal is to replace these odor-impregnated items.
