There are a few options available to you to sanitize containers.
1. Dip the containers into Hydrogen Peroxide and allow to dry. Once the containers are dry, you can fill them.
2. Dip the containers into a solution of bleach and water (1 tablespoon bleach per 1 gallon water). You will have to rinse the containers in water before they can be used, because the bleach will interfere with your product's color and scent.
3. Use a No Rinse Sanitizer like Star-San Sanitizer or other such products. This may not work if you have really hard water. You can find products like this a local home brewing supply store or online.
I hope this helps!
