There are no limits to vinegar and its MANY MANY uses. One of my favorites is the surface spray. I use this for kitchen counters, surfaces, bathroom sink & bathroom toilet/tub (with baking soda scrubbed in first. I also use it to clean my mirrors! It doesnt leave streaks! Its a great all purpose cleaner.
Just mix all into an old spray bottle (hopefully that was full of chemical cleaners and now just got dumped) and presto!
If you have an extra powerful mess (like raw chicken juice) I also spray peroxide first, then the vingar mix over (just in case). The oils and the vinegar have sooo many antibacterial, antimicrobial, antiseptic, antiviral, balsamic, cicatrisant, expectorant, fungicide, insecticide, stimulant and sudorific substance properties that I am sure its fine the way it is!! But.. Just in case! The lemon is antibacterial AND it also helps with the vinegar smell.
Also, as far as the oils are concerned, young living are one of the purest options out there and if you own young living oils you usually only need about a half of the amount of the oils purchased from the store. They are pure and very strong. If you don't own any young living oils yet, let me know how I can help!
