I am looking for some ideas on ways to clean out silicone squonk bottles. I will normally just boil them for a few minutes, and that works well as long as I didn't put too powerful of a flavor in it. For more stubborn flavors I will boil for a few minutes, then fill it with baking soda and let it set for a day or two then boil it again. This method works well, but I just wanted to see if there is any faster or more effective ways that some of you may have came across.
