What Happens If You Mix White Vinegar And Castile Soap?

Keeping your home clean is important for your health and well-being, and there are a slew of cleaning hacks and combinations you can use. However, not all of them are as effective. While white vinegar and castile soap are both used for everything from cutting through grease to homemade tile floor cleaners, you shouldn't mix them together. It doesn't create a dangerous chemical reaction like mixing some cleaners does, so don't panic if you've been using them together. However, combining white vinegar with castile soap results in a less effective cleaning solution than using them both separately.

The reason comes down to their pH. White vinegar is acidic, with a pH between 2.5 and 2.7. That's why there are some things you should never clean with vinegar, as the high acidity can damage certain materials. Castile soap is basic, with a much higher pH. Acids and bases will cancel each other out, and that extends to white vinegar and castile soap. Mixing them together causes them to neutralize each other. The resulting solution isn't harmful, but it isn't useful for cleaning, either. The chemical bonds inside the castile soap break down in the acidic vinegar, causing the soap to separate. That leaves you with a pile of oil and slime that's not particularly pleasant to work with. You can still wipe down your floors or counters with the gloop, but it won't cut through grease and grime as well as either of the ingredients.

Since mixing them isn't dangerous, you could technically continue to do it if you like the texture. However, there's a better way to clean with castile soap and white vinegar that keeps their cleaning power intact. Instead of mixing them, use them in stages. Start with vinegar so the acidity has a chance to break down any tough grime on the surface first, or swap the order to remove hard water residue. If you're starting with vinegar, make sure you know how to clean with vinegar to get the most out of it. Dilute the vinegar with equal parts water so it isn't too acidic. The castile soap needs to be diluted as well. The exact ratio depends on what you're cleaning, so check the bottle or your castile soap's manufacturer's website for specific guidance. Generally speaking, there should be less soap than water in your diluted mix.

Scrub your surface with either the castile soap or the vinegar first, giving it time to sit and work on the dirt and grime. Then, follow it up by wiping the surface down with the other. You don't need to rinse the surface between the steps, but you can if you're worried about mixing them. This should give you the best of both vinegar and castile soap, so you can be sure your surfaces are extra clean. Rinse the soap off with plain water afterwards.
