1. Smoke Cleanse: (Commonly using sage) Using smoke from a burning sage bundle, pass it over the item or being that you would like to cleanse. Focus on your intent while sending out the negative energy. Use incantations if you like. Make sure the plant you are burning is in no way poisonous and is safe! This cannot be stressed enough!

4. Running Water: Make sure the item is unable to be harmed by water! Submerge into a running creek or river. Let it wash away all the negative energies and become charged with positive one. Rainwater can be used as well.
