The pioneers of biologically friendly cleaning supplies.

30 years ago, Dr. John Lopes and Rose Lopes founded Microcide (the company that invented Pro-San) with the simple goal of creating biologically-friendly, safe, and effective cleaning supplies. Their vision was to create a line of alternative safe and non-toxic, eco-friendly, biodegradable cleaners and disinfectants. They have maintained a focus on high quality research and product development.

After hundreds of product iterations, dozens of studies and published research articles, you see the results here with the Pro-San product line and other Microcide products.

Each product is made of food-grade and GRAS ingredients. Each product is made to the highest standards with bio-based and biodegradeable materials.

We care about your health, we care about the environment, and we care about growing an ethical, sustainable company.
