Using just water, the results showed that e-cloths removed over 99% of bacteria, locking them away inside the cloths' fibers, where the bacteria stay until the cloths are rinsed. Further test show that, after a rinse with hot water, e-cloth reintroduced just 0.01% of bacteria back onto a sterile surface. Think about that. Wipe over 99% of bacteria off surfaces and wash it away with hot water. The cloth does not cross contaminate. All without any chemicals. And superior results for surfaces. You really should try them and see for yourself.
