Cleaning kitchen knives with lemon juice?

I heard about cleaning my knives with lemon juice while on a walk with a friend. She had never tried it herself which got me curious to experiment to see if it would actually work.

1. I filled a cup with lemon juice. Find a cup tall enough for your knives. I didn't have enough lemon juice to completely cover my knives, but I figured for this experiment this would be enough. 

2. Soak your knives for 5 - 10 minutes. To get the best results possible I soaked mine for 10. 

3. Scrub your knives with a scouring pad. 

Results: While this did remove some rust and brightened the knives, it was not a miracle worker. I scrubbed hard to get the results that I did. I would say that it's still worth it to remove what it does, just don't expect your knives to be looking like new again.
