Nope - not talking about making salad dressing.
I just thought I woul share a little tip for getting white rings off wood furniture. I found a website that listed a who bunch of tricks to getting those nasty white water rings off wood furniture because I had 2 on my dining room table. Many of the tips seemed too abrasive or I did not have the ingredients for or it took quite a bit of time. So, I went with what I had and it worked perfectly.
Just mix small amounts of equal parts of olive oil (I suppose you could use any oil) and white vinegar. Rub into wood with a cloth. Rub off excess oil residue and Ta Da! The white ring is gone and all it took was 30 seconds of your time.
I was impressed.
