Those in the know will never recommend this! But, if you must, it would be best to get everclear and till the bottle. Spray the contents completely out and repeat. Take the nozzle off and soak it after that. Any gaps or nooks and crannies should be cleaned out with everclear on a Q-tip. Clean every thing. Then let the whole thing soak in everclear for a day. Let it dry off and give it the smell test.
