Vinegar is 5% acetic acid, which fights against bad bacteria and other yuckies you don’t want in your home. White distilled vinegar is best to use for natural cleaning. Vinegar can’t be used on every surface (like marble and granite) and shouldn’t be mixed with castile soap. But even with its limitations, vinegar is a versatile ingredient to keep in your natural cleaning caddy. Use vinegar to make floor cleaner, all-purpose spray, window cleaner, disinfect toilet bowls, and soften laundry.
