Mrs. Meyer's Clean Day All Purpose Cleaner, Lemon Verbena, 32 Ounce Bottle

Q: What proportions of water to concentrate to use when refilling multi-surface spray bottle?

According to Mrs. Meyers website: "The instructions says dilution rate of 1/4 cup concentrate to 1 gallon water. Well, 1/4 cup is 12 teaspoon and 1 gallon is 128 oz. Therefore for the 16 oz Multi-Surface Everyday Cleaner, you'll need 1.5 teaspoon to 16 oz spray bottle at this dilution rate." Only 1.5 teaspoon! Great value.

Q: Is this antibacterial?

Any use of soap with water to clean is antibacterial because it does remove all dirt that harbors bacteria but this does not include the chemicals found in products like Purel/sanitizer products. If you want to make it a better cleaner to also sanitize you can mix in bleach to the solution mix. I do this when I mix the bottle used to clean my bathroom (a mixture of bleach, this concentrate, and water). Adding bleach does make it an antibacterial mixture/cleaner.
