Our microfibre works like little fingers, and as you’re wiping over a surface, it picks up up to 99.9% of all bacteria from the surface. The cloth will pick up the bacteria, and hold onto it. It does not cross contaminate, which means that it holds onto the bacteria and will not drop the bacteria on one side after you've cleaned on another surface. What makes our product unique is the fact that we have silver woven into our microfibre. The silver is a natural antibacterial agent, which means that the cloths will “self-sanitise”. It is a liquid silver that is embedded inside the fibre, and it will not leach or wash out. Many microfibre cloths that you find in the stores will say “anti-bacterial”, but they are coated in an antibacterial agent which washes out over time. Any product that has the “BacLock” sign on it, contains the silver and the cloth will self-sanitise. That means that you don't have to wash the cloth every time you've used it.
