So I found a Lenox vase that my grandmother gave me years ago. It had some kind of strange film inside and I thought I'd just throw it into the dishwasher and clean it.
After the first time through the dishwasher, it came out just as dirty so I put it through a second time.
As you can see - still dirty.
So I thought I'd try something for fun. I poured Heinz distilled white vinegar in the vase and let it sit all day.
Look how wonderfully it came out!
Something so simple and easy - how wonderful!
