Tonight I decided to put a few method's of tarnish cleaning to the test.
1) K's toothpaste idea.
2) The ketchup idea I've heard of.
3) straight up baking soda and water paste.
Hands down K's method is 100% the best one! It was the only method that removed all tarnish and the ketchup method smells AWFUL. And my dog rooted through my laundry and dug out the hand towel with ketchup chewed it up. Score one for Bacchus.
The picture includes all three tests. The bottom image is the ketchup, middle is the baking soda water paste, and the top is K's toothpaste method.
