This product should not be confused with household vinegar. This product is concentrated (75% acetic acid) to deliver the highest possible concentration to consumers. This product is intended to be diluted prior to use. Caution must be used when opening, pouring and using any dilution of this product. This product is provided in a quart size so the consumer has a long-lasting supply at a high concentration so they may dilute as needed rather than buying multiple concentrations for different purposes. One product, one solution, many dilutions.
