What is liquid Castile Soap?

This is a pure soap that is made from olive oil, water & lye (caustic soda). Depending on the type of lye you can make liquid or hard soap.  

Do I need to use distilled water?

Only if you are going to make a large batch that won't be used right away, or your tap water is very hard. Not only should it be free from any contaminates but it has less hard minerals that react with soap. For a small batch that will be used within 4-6 weeks normal tap/boiled water should be fine. 

What essential oils do you recommend for cleaning?

My top oils are Eucalyptus, Lemon, Orange, Lemongrass, Lavender, Tea Tree but the choice is yours & the list is endless when it comes to blends.

Can I add Vinegar to this?

NO NO NO NO NO! You may have heard of recipes that call on mixing vinegar & dish liquid, although this to me is pointless, detergents are not pure soaps & can handle the acid/base reaction.  A pure soap like Castile will turn a milky white when you add vinegar & it will ruin both the Castile  the Vinegar.  

Is this safe for all surfaces?

This spray is safe for all surfaces but when cleaning windows & glass it may leave streaks, in this case you’re best off using the Window & Bath Spray which is basically undiluted vinegar.
