Washdown is a proprietary biotechnology cleaning brand designed for high-performance environments, inspired by biomimicry and grounded in the elements, protecting what matters most: people, the environment and materials.

Traditional cleaning products rely on harsh chemical solvents, synthetic fragrances and abrasive ingredients to break down dirt. Many release volatile organic compounds (VOCs) into the air that contribute to poor indoor air quality and are linked to respiratory irritation and long-term health risks through repeated exposure. These chemicals evaporate into the air we breathe and are also washed into our water systems, entering rivers and marine ecosystems.

Many conventional disinfectants also rely on quaternary ammonium compounds,chemicals designed to remain on surfaces to continue killing microbes. These residues remain on surfaces after cleaning, meaning they are regularly touched and can be absorbed through the skin or inhaled through indoor air. Many traditional cleaning products are also classified as toxic to aquatic life and carry environmental hazard warnings. Increasing research continues to highlight the health impacts of repeated exposure to these chemicals on human and ocean health. Asbestos was once considered safe. Smoking around children was once normal. Education changed that. Cleaning is approaching the same cultural shift. Washdown was created to challenge that system.

Originally developed within the superyacht industry, Washdown uses proprietary biotechnology that works with natural biological processes to break down contamination at the source rather than masking it with chemicals. The formulas are non-abrasive, VOC-free and designed to protect human health, preserve high-value materials, reduce environmental impact and protect
ecosystems. Beyond developing products, Washdown campaigns to raise awareness about the hidden risks of traditional cleaning systems and works to change the culture of cleaning.
