HELP 😬

I have my tongue web pierced and just now thought about my retainer from when I had braces. How do I clean the retainer to make sure I don’t get bacteria into the piercing ? I washed it with soap and water then used tooth paste on it and rinsed it really well. Then I let it soak in mouthwash that has alcohol in it. Is this good enough? Or do I have to boil it??😬
