About Us

Texas Roots. International Reach.

Clean & Shield is a family owned, full-service disinfecting company with over 10 years of experience. We are based in San Antonio, TX where we distribute both wholesale and retail products and also operate a division of professional disinfecting services. We also have a growing network of affiliates across the United States and Mexico that allow us to better meet the needs of our customers. Our products include hand sanitizers, sanitizing sprays, food and hospital grade surface cleaners, soaps and antiseptic to name a few.

We strongly believe prevention is the cure and that is why we use the most innovative products in the industry including our proprietary active ingredient, Zetrisil® which not only kills 99, 99% of virus and bacteria but also protects from re-contamination for up to 28 days.

Zetrisil® - Extra protection developed by My-Shield

What is Zetrisil?

Zetrisil® is a proprietary nano-based silicone compound created by My-Shield that is used solely or in conjunction with either isopropyl alcohol or conventional quaternary ammonium compounds. Zetrisil® effectively protects and/or “shields” the area any My-shield® or Germfree24® product is applied to from bacterial contamination by way of a long-lasting, cationic-charged, anti-microbial nano-silicone coating.

How does Zetrisil® work?

Our Zetrisil-based formulations are effective as a bacterial static to instant complete 99.9999% broad spectrum kill against bacteria & viruses, with the additional benefit of a persistent kill up to 28 days per application.

How is the efficacy of our products measured?

The analysis technique for determining the surface charge of nanoparticles in a solution (colloids) is called “Zeta Potential”. Nanoparticles have a surface charge measured in millivolts that attracts a thin layer of ions of opposite charge to the nanoparticle surface.

Why is Zeta Potential important for Disinfectants & Sanitizers?

The greater the positive charge disinfectants or sanitizing solutions have, the greater killing effect against negatively charged bacteria and virus, by way of opposite pole magnetic attraction.

How does Zeta Potential improve the efficacy of Disinfectants & Sanitizers?

The majority of bacteria and viruses are negatively charged nano particles.

With a positively charged disinfectant and/or sanitizer they will be attracted to each other and agglomerate the negatively-charged bacteria or virus particles around the positively-charged disinfectant or sanitizer solution therefore improving the kill time and efficacy rate per volume of liquid, disinfectant or sanitizer.

Can Zetrisil® kill bacteria and virus’s magnetically?

Yes. By way of changing the magnetic charge around the bacteria or virus cell, it can damage the cell wall membrane causing osmosis imbalance to the bacteria or virus, causing the cell wall to rupture, lyse and explode.

See it in Action

We offer disinfecting services using electrostatic sprayers and our innovative Zetrisil® formulas that kill 99% of viruses, bacteria and harmful germs on contact and continues to protect for up to 28 days.
