Query: great for all kinds of projects!

This is 1 of the most well know oils out there. I bought it because my ac unit outside rattled a little from dirt and dust built up over a few years. I opened it up placed 2-3 drops on key components of the fan/motor and now its whisper quiet. This oil has millions of uses and the value well exceeds the cost. Order a bottle today and you'll probably need to use it soon after you receive it!
