Two real estate offices purchased some used dividers. Used meaning dirty with a variety of past office residue like food, drink, ink, scuff marks, and other questionable attachments.
The units required cleaning by hand so the job was attacked with Aqueous Ozone, white terry cloth rags and a bucket. The result was stain free walls, sanitized and a deodorized work space, a bucket of dirty water and still white terry cloth rags. By generating liquid ozone in the bucket the rags were cleaned as we worked.
