Salt And Lemon Juice Using salt and lemon juice is one of the ways to remove a tattoo. Instead of opting for laser tattoo removal, you can use these ingredients to remove your tattoo naturally. To use this method, mix 100 gms of salt with lemon juice and soak a cotton ball in that solution. Now rub this soaked cotton ball on your tattoo covered skin for about 30-60 minutes till the mixture is deeply absorbed by your skin. Once done, you can wash it off using warm water.
