• a washer body having an upper portion and a lower portion and being rotatable between an in-use horizontal orientation and a totable vertical orientation, the washer body including:
• a wash basin formed within the upper portion and having inner sidewalls, a floor panel and at least one drain aperture defined in the floor panel;
• a cleaning fluid having microorganisms that degrade or remove oil or grease mixed with the cleaning fluid;
• and
• an internal reservoir formed within the lower portion and having a bottom panel spaced from the floor panel, outer sidewalls extending from the bottom panel to top edges of the upper portion of the wash basin, the reservoir configured to receive the cleaning fluid from the wash basin through the at least one drain aperture when the washer body is in the horizontal orientation;
• and the outer sidewalls being spaced from the inner sidewalls to form a perimeter gap portion of the internal reservoir that extends above the at least one drain aperture when the washer body is in the horizontal orientation, wherein the perimeter gap portion comprises at least 50% of a total volume of the internal reservoir.
