Guys, stop with the toothbrush scratching gold or any metal nonsense.
The plastic fibers in the toothbrush are softer on the moh's scale of hardness than any metal and you cannot scratch something with an item that is softer than the metal being rubbed.
Saying it scratches even when you are using it while it is wet with a mild detergent which will act as an additional lubricant is BS.
Sorry, but I had to call you out on this one, its nonsense.
