User Post: Have you found any eco friendly cleaning solutions in your pantry? Would you share?

The main reason why I was looking for something natural was my "dear" bathroom sink, sluggish it must be hair or something, I hoped...then I found these gems, I poured baking soda down the drain followed by good 'ol white distilled vinegar, waited a few minutes poured some hot water (not scalding) mind you.
And voila! It worked! No more sluggish drain.
After that I saw all the great stuff these two could do.

Have you found anything that helps you clean easier and is eco friendly?Do tell.
