That’s why I stick to the food container rule. If it’s a bottle food came in, it’s safe to use.
The exception being milk bottles. I have never found a way to get rid of the eventually rancid milk smell.
Someone told me once the milk proteins bind to the plastic and there is no way to clean it totally.
So I just pitch them.
Be careful with juice containers as well. Some can be used, some can’t. I mention that for those who may not know.
